Dimensions

The charts below list the dimensions, drilling and approximate weights of our Class 150 and Class 300 raised face socket weld flanges, 1/2" to 4". Full Class 150 and Class 300 charts for every raised face and lap joint flange type are on our stainless steel flanges page.

Dimensions in inches; weights are approximate, in pounds each. A dash means no value is listed.

* Includes the 1/16" raised face, as on our data sheet; current ASME B16.5 tables list these dimensions 1/16" smaller.

‡ ASME B16.5 sets socket depth only for sizes up to 3"; above that it is up to the manufacturer.

B1 is the standard bore; ask us about other bores. Call us for stud and machine bolt lengths.

Additional Info

Stainless steel raised face socket weld flanges take the end of the pipe in a socket. The raised face is engineered to concentrate more pressure to a smaller area on the flange, which provides an increased containment capability at higher pressures. The flange needs to be welded to the pipe. Socket weld flanges were originally designed for smaller, high pressure pipe.

Frequently Asked Questions

What sizes of raised face socket weld flanges do you carry?

The product table on this page lists 304 and 316 stainless steel raised face socket weld flanges from 1/2" to 4" in Class 150 and Class 300. For other sizes, classes or alloys, call (800) 282-9694 or send us a message.

What are the dimensions of a 1" Class 150 socket weld flange?

A 1" Class 150 raised face socket weld flange is 4.25" OD and 0.56" thick (including the 1/16" raised face), with a 0.50" deep socket, a minimum socket bore of 1.36", a 1.05" bore B1, and four 1/2" bolts on a 3.12" bolt circle. It weighs about 2 lb.

How deep is the socket?

It depends on the size: from 0.38" at 1/2" to 0.81" at 3". ASME B16.5 sets socket depth only for sizes up to 3"; above that it is up to the manufacturer. For 3-1/2" and 4", our Class 150 chart lists 0.88" and 0.94" from our data sheet (marked ‡); our Class 300 data sheet lists none.

What specifications do your socket weld flanges meet?

Our ANSI flanges meet the ASTM-ASME A182 material specification and the ASA B16.5 dimensional specification.
