SP-119

FOREWORD ASME B16.9 is the American Standard for steel butt-welding fittings and although not so stated, it is implied that its scope deals primarily with standard (Schedule 40) wall and heavier as it was developed for carbon steel and those grades of alloy steel piping that are selected for pressure and temperature considerations. In 1949 ASME approved standard B36.19 for Stainless Steel Pipe in which Schedule 10S was established. Schedule 5S pipe was recognized in the 1952 publication of B36.19. The companion fittings for Schedule 10S pipe used B16.9 shapes and proportions and were standardized by MSS SP-43, which was first published in 1950. In anticipation, the original 1950 edition of MSS SP-43 also standardized Schedule 5S fittings. Since 1950 the use of lighter than standard wall stainless steel piping in new construction has become predominant. The reasons for this evolution include the rapid expansion of the process industries in the fields of chemicals, plastics, textiles, paper, etc. Coincident with the greater utilization of light wall pipe and of more capable metal forming machinery, the need to reduce pipe assembly fabrication times brought about by world market competition led to the development of belled end socket welding fittings. As with the development of MSS SP-43, the shapes and proportions for B16.9 were reused for the belled end fitting bodies to the maximum extent possible.

In keeping with trends wherein military procurement activities have been using more commercial material standards and because of recognized fabrication economies related to the use of these fittings, the U.S. Navy sponsored the writing of the 1996 edition of this Standard Practice in cooperation with fitting manufacturers. This Standard Practice established dimensional uniformity for light wall belled end socket welding fitting designs qualified by burst and fatigue testing for Military Service and qualified by burst testing for Commercial Code Practice. The most significant changes in the 2003 revision included the following: 1) A new definition for allowable pressure ratings for MP fittings (Section 6), which adopts the B16.9 format rating the fitting the same as the connecting pipe of the same schedule; 2) The addition of titanium and aluminum fitting materials; and 3) The addition of the Supplementary Requirements (Section 18, now 17), which supports Navy special requirements. The most significant changes in this 2010 revision include the following: 1) The extension of the SCOPE to include heavier wall fittings; 2) The relocation of the CR fitting requirements from the body of the Standard Practice to that of a Supplementary Requirement; 3) The addition of all the combinations of reducing fittings included in B16.9; and, 4) The addition of a reference line on the socket end to enable inspectors to measure the installation weld length – as a Supplementary Requirement. The title of this 2010 revised Standard Practice has also been amended. ii Copyright MSS Provided by IHS under license with MSS No reproduction or networking permitted without license from IHS

In 1992 first work on belled end fittings for this Standard Practice included defining socket proportions, socket to fitting body transition geometry, fitting thickness, and determining the ability of U.S. industry to support manufacturing. Some of this work only standardized service proven relationships used in belled end fittings made for the pulp and paper industry without standards for over 20 years. In 1994 the U.S. Navy funded burst and fatigue testing prototype fittings in the first of a two-phase program. The second phase was for an increased thickness fitting and was never done. In 1995 mid-way through testing, the Navy directed that these belled end fittings be used on ship systems in new construction followed shortly thereafter by direction to use them on the repair of ship systems. The quality and configuration control of these fittings was done by an interim document, the requirements of which, with some improvements, are contained herein.

FACTORY-MADE WROUGHT BELLED END PIPE FITTINGS FOR SOCKET-WELDING

1. SCOPE 1.1 General This Standard Practice covers the design and manufacturing requirements for factory-made wrought belled end pipe fittings for socket-welding formed from either tubular sections or flat material. Included are the overall dimensions, tolerances, materials, socket end details, heat treatment, marking and other requirements for belled end fittings in sizes NPS 1/2 through 12. The requirements for these belled end fittings are stipulated into each of two pressure service classes:

1.4 Service Conditions This Standard Practice does not cover the criteria for selection of fitting type or fitting materials suitable for a particular fluid type or service. 1.5 Installation Welding This Standard Practice does not cover installation-welding requirements. Installation welding shall be done in accordance with the applicable piping system into which the fittings are installed. Pipe joint weld geometry suggestions contained in Section 13 reflect the proportions used in the fatigue tests conducted on pipe pieces used to qualify these fittings for Navy service.

1.1.1 Class MP for stainless steel fittings for use with ASTM A312 pipe; for titanium fittings for use with ASTM B861 or B862 pipe; and aluminum fittings for use with ASTM B241 pipe.

2. REFERENCES 2.1 General Standards and specifications adopted by reference in this Standard Practice are shown in Annex A, for the convenience of identifying edition number, date and source of supply.

1.1.2 Class MARINE for copper nickel fittings for use with Military Specification MIL-T-16240 pipe or ASTM B466 or B467 pipe. 1.2 Partial Compliance Fittings This Standard Practice may be used to specify Partial Compliance (PC) fittings by agreement between the manufacturer and purchaser. Special considerations include, but are not limited to: dimensions; such as unlisted reducing tee outlet size combinations, or end shapes; such as a street end tee, or custom tolerances. When such fittings meet all other stipulations of this Standard Practice, they shall be considered as being in Partial Compliance herewith, provided they are appropriately marked (see Section 16).

3. DEFINITIONS 3.1 General Wrought Belled End Fittings for Socket Welding add the advantages of socket welding joints to ASME B16.9 shape butt-welding fittings. In this Standard Practice, "wrought" is used to denote fittings formed from tubular or flat starting materials as opposed to those, which are either forged or cast to their final shape or machined from forgings or castings. 3.2 CuNi CuNi is a notation representing copper-nickel alloy. The two most common alloys are 90/10 and 70/30. The most commonly used pipe specification is MIL-T16420.

1.3 Fitting Shapes and Types Not Covered This Standard Practice does not cover the design or construction of laterals, wyes, mitered elbows, tees of notch and point or saddle weld types, sweep elbows, sweep tees or any other fitting not described herein by sketch and table.

4.3 Subclass Substitution If the purchaser does not define a MP subclass, the manufacturer may supply any MP subclass.

been saturated with any one of several electrolytes formulated for marking various metals. When the marking head touches the fitting, the current and electrolyte flow through a stencil resulting in the replacement of metallic ions with a metal oxide forming an etched mark.

5. PRESSURE RATINGS 5.1 Class MP Ratings The allowable pressure ratings for Class MP fittings designed in accordance with this Standard Practice may be calculated as for straight seamless pipe of equivalent material (as shown by comparison of composition and mechanical properties in the respective material specifications) in accordance with the rules established in the applicable section(s) of the ASME B31 Code for Pressure Piping. For the calculation, applicable data for the NPS, wall thickness class or schedule number and material equivalent to that of the fitting material shall be used. NPS, wall thickness class or schedule number and the material identity on the fittings are in lieu of pressure rating markings.

3.4 Controlled Dot Peen Controlled dot peen is a mechanical process using a carbide stylus to create a controlled depth dot matrix impression in the metal being marked. 3.5 Heat Identification Number The manufacturer's heat identification number traces the starting material to a heat number or a lot number. 3.6 Symbols Reference The definition reference for symbols and abbreviations is MSS SP-96. 3.7 Factory-made Factory-made means production facilities, manufacturing methods (using tools, dies, jigs and fixtures), and inspection procedures to a quality control system of a standard line of socket weld fittings.

5.2 Class MARINE Ratings The allowable pressure rating for Class MARINE fittings shall be the same as those for the MIL-T16420 Class tube with which it identifies. 5.3 Rating Certification The pipe fitting manufacturer certifies that its pipe fittings comply with this Standard Practice when its name or trademark is marked on the body of the fitting.

4. CLASSIFICATIONS 4.1 General Fittings in full compliance of this Standard Practice shall be one of two classes: MP or MARINE. The classes are specified in Table 1 for ready reference and comparison. Fittings of Class MP shall be further subdivided into four subclasses; specifically: MP-S, MP-W, MP-WX, and MP-WU, each reflecting unique manufacturing processes and inspection requirements.

6. FITTING DESIGN 6.1 Design Qualification The pressure retaining designs of Class MP or MARINE fittings are qualified simultaneously with the qualifications of manufacturing methods for each fitting design and those qualifications shall be by proof test (see Section 7).

4.2 Special Class Fittings Class CR fittings are described in the SR (Supplementary Requirements) section of this Standard Practice. CR Class fittings shall have the same exterior dimensions as MP and MARINE fittings, but thickness, manufacturing methods and quality control inspection requirements shall be as agreed between the manufacturer and a purchaser.

6.2 Minimum Thickness The minimum wall thickness of each fitting shall be the same as the minimum wall of the pipe or tube with which it identifies. In addition, in order to meet proof test and/or manufacturing process requirements, some portions of formed fittings will be thicker than the minimum wall thickness.

STANDARD PRACTICE c)

6.3 Class MP Fittings made from Other Fittings Class MP fittings may be fabricated from ASME B16.9 fittings wrought to class WP per ASTM A403 on to which tangent ends have been butt welded. The tangent ends may be either street or bell and belling may be done either before or after attachment.

7.2 Re-testing Re-testing shall be required for any change in manufacturing method, which directly affects the tested component in a way which could reasonably be concluded to change pressure containment performance. Examples include a localized reduction in fitting thickness or a localized decrease in surface curvature radius. 7.3 Concurrent Fitting Qualifications of Different Sizes and Types For each fitting type and unique method of manufacture, the proof test of one NPS size qualifies fitting sizes from one half to twice the NPS size tested. Further, tests performed on 90° long radius elbows qualify 45° elbows. Tests performed on straight tees qualify reducing tees. Tests performed on eccentric reducers qualify concentric reducers. In addition, tests performed on belled end fittings qualify street end fittings of the same geometry and manufacturing methods.

6.5 Class MARINE Extruded Tees Class MARINE thermometer well tees and other tees utilizing extruded branch connections shall be fabricated in accordance with NAVSEA S9074-AR-GIB-010/278 requirements for extruded outlets. The nominal pipe size of thermometer well tee fittings shall not exceed NPS 2. 7. MANUFACTURING METHOD PROOF TESTING 7.1 Requirement to Test The validity of each unique manufacturing method used to make each type of Class MP and MARINE fitting shall be affirmed by pressure testing in accordance with applicable sections herein, except that the strength of straight couplings and concentric reducing couplings may be proven by calculations.

7.4 Concurrent Fitting Qualifications of Different Materials For those fittings differing only in material alloy, wherein the geometry, manufacturing methods, and size are the same and the yield/tensile strength ratios are proportional, the pressure retaining capacity of the fitting will be directly proportional to the tensile properties of the various material alloys. Accordingly, the successful proof test of a 90/10 alloy CuNi fitting will qualify a 70/30 alloy CuNi fitting and vice versa and the successful test of a Type 304 stainless steel fitting will qualify Types 316 and 321 stainless steel fittings, and vice versa. In those metal alloys wherein the yield/tensile strength ratios are not proportional, for instance: aluminum and titanium alloy fittings, each alloy must be tested.

7.1.1 Unique manufacturing methods are determined by any one of the following attributes: Fittings formed from tubular sections are unique from those formed directly from flat material.

b)

Fittings formed employing one fabrication weld are unique from those employing either zero or two fabrication welds.

Fittings formed from a greater or lesser number of pieces are unique.

7.1.2 Fitting types include long radius elbows, short radius elbows, tees, reducing tees, concentric reducers, eccentric reducers, and caps.

6.4 Class MP Extruded Tees Class MP thermometer well tees and other Class MP tees utilizing extruded branch connections shall be fabricated in accordance with the applicable section of ASME B31 Code for Pressure Piping, under requirements for extruded outlets. The nominal pipe size of thermometer well tee fittings shall not exceed NPS 2.

P = Minimum manufacturing proof-test pressure.

7.5 Concurrent Fitting Qualifications made from Seamless or Welded Starting Materials The successful proof test of a fitting made from pipe or tube starting material, which starting material has a longitudinal weld made by the pipe or tube manufacturer, shall qualify the same fitting (same manufacturing methods and same minimum schedule or pressure class) made from seamless starting material and vice versa.

7.9 Maximum Test Pressure Small fittings are inherently robust and can be difficult to proof test within the capabilities of normally available laboratory equipment. Accordingly, the proof test is considered successful if the assembly withstands a pressure of 10,000 psig. 7.10 Record Keeping Pressure test results shall be kept on file by the fitting manufacturer and shall be made available to the purchaser upon request. Certified results of test specimen tensile testing and material heat or lot number shall be included in the test result documentation.

7.6 Concurrent Fitting Qualifications of Different Thicknesses Successfully performed proof tests may be used to qualify other fittings, which differ only in material thickness, within the range of t/D quotients from one half to three times that of the tested fitting. The t and D values are defined in the Testing Procedure paragraph, herein.

8. PRODUCTION TESTING 8.1 Tests of each Fitting Hydrostatic testing of production fittings is not required by this Standard Practice; however, each fitting of either Class MP or MARINE shall be capable of withstanding without failure, leakage or impairment of service-ability, a test pressure equal to that prescribed for the specified matching pipe of equivalent material and minimum wall thickness.

7.7 Test Pipe Piece Design Preparatory to proof testing, straight pieces of pipe shall be welded on to the end of each fitting and these pieces shall be capped. The length of the pipe pieces between fitting and cap welds shall be a minimum of one pipe outside diameter. The pipe shall be of the same material and at least as strong as the fitting. The test shall be performed on unrestrained fittings.

9. MATERIALS 9.1 Stainless Steel Fittings Stainless steel fittings shall be made from tubular or flat starting material, or a combination of both, the chemical composition and mechanical properties of which conform to ASTM A240, ASTM A312, or ASTM A358.

7.8 Testing Procedure Hydrostatic pressure shall be applied until the fitting or pipe ruptures. The actual test pressure prior to rupture must at least equal the computed proof-test pressure. Alternatively, the test is successful if the assembly withstands, without rupture, 105 percent of the computed proof-test pressure, defined as follows:

9.2 Copper-Nickel Fittings Copper-nickel fittings shall be made from tubular or flat starting material, or a combination of both. Tubular starting material shall conform to the chemical composition and mechanical properties of MIL-T-16420, or ASTM B466 or B467. Sheet starting material shall conform to Military Specification MIL-C-15726 or ASTM B122.

10.3.4 When required (see Table 1), welds shall be liquid dye-penetrant examined in accordance with Appendix 8 of Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code. 10.3.5 All welds in Class MARINE fittings shall be inspected to the requirements of NAVSEA S9074-AR-GIB-010/278 for Class P-2 piping.

10. WELDING AND WELD INSPECTIONS 10.1 Welds and Welder Qualifications Welders, welding operators, and welding procedures shall be qualified under the provisions of Section IX of the ASME Boiler and Pressure Vessel Code, for fabrication welds used in the manufacture of all classes of fittings except MARINE (see Table 1). Pipe welds in starting material made without the addition of filler metal do not require such qualification. For MARINE class fittings, welding procedures and welder performance qualifications shall be per NAVSEA S9074AQ-GIB-010/248.

10.4 Weld Repair Weld repair is permitted only to longitudinal welds joining half shells or circumferential welds joining tangents to fittings. Repaired fittings shall be re-examined and re-heat treated. No other repairs by welding are permitted. 11. FITTING TOLERANCES, DIMENSIONS AND LAY-OUT DISTANCES 11.1 Dimensional Tolerances Socket depth, inside diameter and fitting overall tolerances are specified in Table 2.

10.2 Weld Design and Crowns Welds shall be made with a full penetration butt joint. The crowns of the welds shall rise no more than 1 /16 inch above the fitting surface on the inside or on the outside. Permanent backing strips shall not be used. Fittings fabricated from half shells that are longitudinally welded shall have the interior crowns of the longitudinal welds removed for a distance of the socket and the transition prior to the belling operation. 10.3 Weld Inspection Requirements 10.3.1 Fitting weld inspection requirements and starting material weld inspection requirements are specified in Table 1. 10.3.2 When required (see Table 1), welds shall be radiographically examined throughout their entire length in accordance with Paragraph UW-51 of Section VIII, Division 1 of the ASME Boiler and Pressure Vessel Code.

11.4 Fitting Dimensions, General Fabrication Dimensions for fittings are specified in Tables 4 through 18.

13.1 For Installation Guidance, only During Navy sponsored and controlled fitting qualification testing, optimum fitting to pipe joint fatigue performance was attained when the height of the joint fillet was equal to the fitting socket-face thickness () and extended 1.75 times that distance along the length of the pipe as shown in Figure 1. The slope of the weld face, when measured from the pipe surface, should be approximately 30 degrees. In addition, pipe cut-lengths were positioned 1 /16 to 1/8 inch from the bottom of the socket to allow for expansion when welding.

11.5 Layout Data The distances shown in the fitting sketches from the center of fittings to a pipe piece (see Tables 4 through 18) are pipe fabrication assembly dimensions, which are provided for use in system layout drawings. Accordingly, these distances are not assigned fitting manufacturing tolerances. 12. SOCKET AND COUPLING END FACES 12.1 End Face Finish The socket-end and coupling-end faces shall be flat and perpendicular to the socket and coupling axes. The socket-end and end face wall thickness serves as a guide for pipe joint fillet weld height.

as allowed in Section 15.1. Heat treating shall be performed at 1300 +/- 50°F (704 +/- 28°C) for one hour at temperature per inch of thickness.

discontinuities, surface checks (fish scale), or mechanical marks shall not encroach upon the minimum wall thickness and shall be removed by machining or grinding to sound metal and the repaired areas shall be well faired. When the removal of a surface discontinuity reduces the wall thickness below the minimum wall limits for the pipe Class or schedule with which the fitting identifies, the fitting shall be rejected.

15.4 Titanium Fittings All titanium fittings shall be stress relieved, except as allowed in Section 15.1. The heat treatment shall consist of holding the fitting at a minimum temperature of 1100°F for not less than 1/2 hour per inch of thickness. The minimum time at temperature is 15 minutes.

14.2 Surface Corrosion Stainless steel surfaces shall be free of scale, cleaned and passivated. Copper-nickel surfaces shall be free of black oxide. Titanium and aluminum surfaces shall be cleaned and free of discoloration (see ASTM B600).

15.5 Aluminum Fittings All aluminum fittings shall be stress relieved in accordance with ASTM B918 after forming, to meet the grade specified. 16. MARKING

15. STRESS RELIEVING TREATMENT 15.1 General Each fitting shall be stress relieved after completion of all welding or body-forming operations, except that the forming of socket ends may be performed either prior to or after final stress relieving. In addition, Class 200 and thinner and Schedule 10 and thinner pipe couplings formed from annealed pipe do not require stress relieving.

16.1 General All fittings shall be permanently marked by electro-etching, controlled dot peen, or engraving pencil. Any electrolyte used shall not contain harmful amounts of chlorides, metals, or metallic salts, such as zinc or copper, which would cause corrosive attack on heating. No metal impression stamps shall be used.

15.2 Stainless Steel Fittings All stainless steel fittings shall be furnished stress relieved except as allowed in Section 15.1.

17.5 Supplementary Requirement-4: Substitutions The Class 200 copper-nickel “NAVY” fitting defined by NAVSEA drawing 802-5959353 was the precursor design upon which the “MARINE” fitting in this Standard Practice was based. The two fittings are functionally identical for every shape. Form exceptions include the tangent end on standard radius street end elbows, and the overall lengths of eccentric and concentric reducers, each of which is slightly longer in the MARINE fitting design. In addition, the wall thickness of NAVY short radius elbows has been revised downward for the MARINE fitting in order to suit the revision of ASME B16.28 wall thickness requirements, after which the NAVY and MARINE short radius elbow designs were originally patterned. Essentially, the MARINE fitting is a NAVY fitting, which has been updated to include developments, corrections and current quality control requirements. Accordingly, those who would otherwise specify NAVY fittings are encouraged to substitute the MARINE fittings in order to standardize fitting designs and reduce the redundant inventories of functionally identical fittings.

Note: The minimum wall thicknesses of other classes and schedules are calculated similarly.

17.4 Supplementary Requirement-3: Corrosion Resistant, “CR”, Fittings 17.4.1 CR fittings are fittings of unspecified pressure class, which are supplied for low fluid pressure services. Examples include gravity drainage, tank sounding tube, tank vent, tank overflow, mechanical conduit and other applications where pressure containment is not a primary design consideration. --`,`,`,`,,``,`````,`,`,,``,,,,,-`-`,,`,,`,`,,`---

MINIMUM WALL THICKNESS DATA TABLE NOTES (a) This ready-reference data table is provided for the most often manufactured fitting Class and schedule. For other Classes and schedules, see General Note 2, below. (b) Minimum wall thickness for aluminum pipe NPS 1/2 and NPS 3/4 pipe is 0.071 inches. (c) MIL-T-16420 lists 0.151 for alloy 706 (90/10) and 0.148 for alloy 715 (70/30). GENERAL NOTES: 1) Street end outside diameter tolerances shall be the same as the pipe with which the fitting identifies. 2) Fitting minimum wall thicknesses are the same as for the pipe or tube with which they identify. (For guidance: Generally, the nominal and minimum wall thicknesses are the same in a tube-formatted specification, while minimum walls are 871/2% of nominal walls in a pipe formatted specification. MIL-T-16420 is a tube-formatted copper nickel material specification for both tube and pipe sizes although, it is most commonly used to specify pipe sizes. Consequently, each nominal and minimum wall thickness in that specification, MIL-T-16420, is the same for each tube size and for each pipe size.) 3) CR fittings wall thickness requirements are not specified.
