Socket Weld and Threaded Fittings

High Pressure Fittings - General This subsection summarises requirements for high pressure (HP) socket weld and threaded fittings as defined in ASME/ANSI B16.11-1991 and BS 3799:1974. Dimensions are reproduced in pages 7-6 to 7-25, including coverage of Outlet fittings that are also used in high pressure applications.

Specifications The specifications applicable to high pressure socket weld and threaded fittings are as follows:

❍ ❍

ASME/ANSI B16.11-1991 - Forged fittings, socket-welding and threaded. BS 3799:1974 - Steel pipe fittings, screwed and socket-welding for the petroleum industry. This specification is substantially the same as B16.11.

A summary of the fittings, sizes and pressure ratings (class designations) covered by B16.11 and BS 3799 is provided in the tables below. The first table also shows the pipe weights defined as compatible with the various classes of fitting.

Notes 1 Class designations correspond to the maximum cold working pressure of fittings in pounds force per square inch. 2 The wall thicknesses quoted are not restrictive but do correlate for calculation of pressure ratings. Thicker or thinner pipe may be used, but when thinner pipe is used its strength should govern the pressure rating. 3 Bore dimensions for Class 3000 lb socket welding fittings correspond to Schedule 40 pipe. 4 Bore dimensions for Class 6000 lb socket welding fittings correspond to Schedule 160 pipe.

Manufacture ❍



ASME/ANSI B16.11-1991. ASME/ANSI stainless steel socket weld or threaded fittings are most commonly manufactured from material conforming to ASTM A182 (see page 4-6). BS 3799:1974. Manufacturing requirements are substantially the same as for B16.11. Stainless steel grades specified are as indicated in the pressure/temperature ratings table on page 7-4.





Marking should include (in priority order): - Manufacturers name or trademark - Material identification (in accordance with A 182, - Class or pressure ratings (e.g. 3000 lb) - Size Markings may be omitted (least priority first from above list) if fitting size or shape imposes limits. Outlets. Socket weld and threaded outlets comply with B16.11 requirements, although B16.11 does not specifically cover outlets.

Pressure Ratings ❍ ❍

General. The Class designation (e.g. 3000 lb) of the high pressure fittings indicates the maximum cold working pressure. ASME/ANSI B16.11 Fittings. ASME/ANSI B16.11 specifies the allowable pressure/ temperature rating to be that of seamless pipe of the equivalent material and wall thickness.
