FOREWORD

ASME B16.9 is the American S,tandard 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 SP43 which was first published in 1950. In anticipation, the original 1950 edition of MSS SP43 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 SP43, the shapes and proportions of B16.9 were reused for the belled end fitting bodies to the maximum extent possible.

In 1992 first work on belled end fittings for this standard included socket proportions, socket to fitting body transition geometry, fitting thickness, and 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.

In keeping with recent 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 this Standard Practice in cooperation with fitting manufacturers.

This Standard Practice establishes dimensional uniformity for light wall belled end socket welding fitting designs qualified by burst and fatigue testing for both Military Service and Commercial Code Practice.

BELLED END SOCKET WELDING FITTINGS, STAINLESS STEEL AND COPPER NICKEL

1. SCOPE

l. 1 This Standard covers 1 /4 through NPS 12 stainless steel and copper-nickel belled end socket welding fittings, including dimensions, tolerances, materials, socket end details, heat treating and marking requirements for use with the following pipe standards:

a) ASME B36.19 (Sch SS and 10s)

b) ASTM B 466

c) ASTM B 467

d) MIL-T-16420 (Class 50 and Class 200 tube)

2. REFERENCES

2.1 Standards and specifications adopted by reference in this standard are shown in Annex A, for convenience of identifying edition number, date and source of supply.

3. SPECIAL CONSIDERATIONS

3.1 Tees fabricated by welding a branch to an outlet extruded from the run are allowable and shall be designed and manufactured in accordance with ASME B31 Codes for Pressure Piping as pipe fabrications. Thermometer well tees shown herein are pipe fabrications with envelopes dimensionally standardized by this Standard Practice. Refer to Section 12 for Fabrication Alternatives.

3.2 Partial Compliance Fittings may be made to special dimensions - such as unlisted reducing tees, sizes - such as NPS 31/2, shapes - such as a street end tee,. tolerances, or of wrought materials other than those covered by this Standard Practice by agreement between the manufacturer and the purchaser. 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 Paragraph 19.4).

3.3 Laterals, wyes, mitered elbows, and tees of notch and point or saddle weld constructions are not covered by this standard.

4. DEFINITIONS

4.1 Belled End Socket Welding Fittings are a family of relatively thin wall wrought fittings which extend the advantages of socket welded joints through the common sizes of thin walled pipes. In this Standard Practice, "wrought" is used to denote fittings formed from tubular or flat starting materials as opposed to those that are either forged or cast to their final shape or machined from forgings or castings.

4.2 CUNI is a nota;ion representing copper nickel alloy.

4.3 Electro-Etch is an electrochemical marking process which consists of an electrical power unit that delivers current to a marking head. The marking head is covered with a pad that has 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.

4.4 Controlled Dot Peen is a mechanical process using a carbide stylus to create a controlled depth dot matrix impression in the metal being marked.

4.5 Manufacturer's Heat Identification Number traces the starting material to a heat number or a lot number.

4.6 Definition reference for symbols, abbrevia- tions and other definitions may be found in MSS SP-96.

5. CLASSIFICATIONS

5.1 Fittings shall be one of three classes: MP, MARINE or CR. The classes are specified in Table 1 for ready reference. 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. Class MARINE shall only apply to copper nickel fittings. Class CR shall only apply to stainless steel fittings.

5.2 Class MP or MARINE or CR shall be specified by the purchaser. If the purchaser does not define a MP subclass, any may be supplied by the manufacturer. Class CR fittings shall not be substituted for fittings marked MP, but Class MP may be substituted for Class CR.

7. FITTING DESIGN

7.1 The designs of MP Class fittings are qualified simultaneously with the qualifications of manufacturing methods for each fitting design and those qualifications shall be by proof test (see Paragraph 8).

8. FITTING DESIGN AND MANUFACTURING METHOD PROOF TESTING

8.1 The validity of each unique manufacturing method used to make each type of MP and MARINE Class fitting shall be affirmed by pressure testing in accordance with applicable sections herein.

8.2 Unique manufacturing methods are deter- mined by the following attributes:

6. PRESSURE RATINGS

6.1 The allowable pressure ratings for MP Class fittings designed in accordance with this Standard Practice shall be 87%% of those calculated for straight seamless pipe of minimum wall thickness and stress value in accordance with the rules established in the applicable sections of ASME B31, Codes for Pressure Piping. The pipe wall thickness, schedule or class and material type shall be that with which the fittings have been ordered to be used; their identity on the fittings is in lieu of pressure rating markings.

6.2 The allowable pressure ratings for MARINE class fittings shall be the same as those for MIL-T-16420 Class 200 tube.

6.3 The allowable pressure ratings for CR class fittings shall be the same as those listed for CR class fittings in MSS SP43 for materials listed therein.

6.4 The pipe fitting manufacturer certifies that his pipe fitting complies with this Standard Prac- tice when his name or trademark is marked on the body of the fitting.

a) Fittings formed from tubular sections are unique from those formed directly from flat material, irrespective of whether such sections are seamless or welded construction.

b) Fittings formed employing one fabrication weld are unique from those employing two fabrication welds.

c) Fittings formed from a greater or lessér number of pieces are unique.

8.3 Retesting shall be required for any change in manufacturing method which directly affects the tested component in a way which could reasonably be concluded to reduce either pressure containment or fatigue performance. Examples include a localized reduction in fitting thickness or a localized decrease in surface curvature radius.

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

8.5 For each fitting type and unique method of manufacture, the pressure test of one NPS size

2




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 a straight tee qualify reducing tees. Tests performed on eccentric reducers qualify concentric reducers. Tests performed on short couplings qualify long couplings and vice versa.

8.6 Pressure test results shall be kept on file by the fitting manufacturer and shall be made available to the purchaser upon request.

8.7 Preparatory to pressure testing, straight pieces of pipe shall be welded on to the end of each fitting and these pieces shall be capped. The pipe pieces shall be no shorter than twice the pipe outside diameter. The pipe shall be of the same material as the fitting.

8.8 Hydrostatic pressure shall be applied until the fitting or pipe ruptures. The test pressure prior to rupture shall be at least equal to 105% of the minimum manufacturing proof test pressure defined as follows:

P = 2St/D, where:

S = Actual material tensile strength deter- mined from a specimen representative of the test fitting in the same stress relieving heat treat condition,

t Minimum allowable pipe wall thickness,

D = Specified outside pipe diameter, and

P = Minimum manufacturing proof test pressure.

9. PRODUCTION TESTING

9,l Hydrostatic testing of fittings is not required in this standard; however, each fitting ' of either class MP or MARINE shall be capable of withstanding without failure, leakage or impairment of serviceability, a test pressure equal to that prescribed for the specified matching pipe of equivalent material and minimum wall thickness. Class CR fittings shall be capable of withstanding

10.

11.

a hydrostatic test pressure equal to one and one- half times the pressure ratings listed in MSS SP-43 for class CR fittings.

SIZES

10.1 The sizes of fittings, excepting only short radius elbows and thermometer well tees shall be from NPS 1/4 through NPS 12. Short radius elbows shall be from NPS 1 through NPS 12. Thermometer well tees shall have a body size of no larger than NPS 2.

10.2 All combinations of reducing tees listed in ASME B16.9 are available from manufacturers, however the following sizing standard is established in the Tables herein and is encouraged in practice:

a) For reducing run tees: Use a standard tee with street reducer.

b) For reducing branch tees in sizes NPS 2 and smaller: Use straight size tees and a street reducer.

c) For reducing branch tees in sizes larger than NPS 2 Use straight size or half size reducing branch tees with street reducers to create all other combinations.

MATERIALS

11.1 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 A 240, ASTM A 312, or ASTM A 358.

11.2 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 Military Specification MIL-T-16420, or ASTM Designation B 466 or B 467. Sheet starting material shall conform to MIL-C-15726 or ASTM Designation B 122.
