How Do Socket Weld Flanges Work?

Socket Weld Flanges feature an internal recessed socket designed to accommodate the end of a pipe.

During installation, the pipe is inserted into the socket and positioned with the specified expansion gap between the pipe end and socket shoulder. This clearance is important to avoid excessive stress during welding and operation.

The flange is then attached to the pipe using an external fillet weld performed according to an approved welding procedure.

After welding and required inspection, the flange is connected to a compatible mating flange using suitable gaskets, studs, and nuts.

The socket arrangement supports accurate pipe positioning and provides a strong mechanical connection for suitable industrial services.

However, the socket joint contains an internal crevice, which can make it less suitable for certain highly corrosive, hygienic, or crevice-sensitive applications. For severe cyclic loading or other critical conditions, alternative welded connections may be required by the governing piping code.

Frequently Asked Questions About Socket Weld Flanges

What is a Socket Weld Flange?

A Socket Weld Flange is an industrial pipe flange featuring an internal socket into which a pipe is inserted and attached using an external fillet weld.

What are the advantages of Socket Weld Flanges?

Socket Weld Flanges provide convenient pipe positioning, compact construction, and strong welded connections for suitable small-diameter piping applications.

What is the difference between Socket Weld and Slip-On Flanges?

Socket Weld Flanges have an internal shoulder that positions the pipe and typically require an external fillet weld. Slip-On Flanges slide over the pipe and are normally attached using internal and external fillet welds.

Are Socket Weld Flanges suitable for high-pressure applications?

Yes. Socket Weld Flanges can be suitable for high-pressure service when the flange pressure class, material grade, pipe size, weld design, and governing piping code permit their use.

What is the difference between Socket Weld and Weld Neck Flanges?

Socket Weld Flanges use a recessed socket and fillet welding, while Weld Neck Flanges feature a tapered hub and use a butt-welded connection. Weld Neck Flanges are often preferred for more demanding cyclic or fatigue-sensitive services.

Which materials are used for Socket Weld Flanges?

Common materials include ASTM A105 carbon steel, ASTM A182 stainless steel and alloy steel, ASTM A350 low-temperature carbon steel, and selected corrosion-resistant alloys.

Which standards apply to Socket Weld Flanges?

ASME B16.5 covers applicable Socket Weld Flange dimensions, materials, pressure-temperature ratings, and tolerances. Welding and installation requirements are governed by the applicable piping code and project specifications.
