One-Minute Overview

Forged stainless steel socket weld flange rated 1 inch, 150LB, with a raised face.
Socket weld joint suits small bore pipe in high temperature, high pressure duty.
Good sealing and easy installation and disassembly speed up tie-ins and repairs.
Specified for lines that carry flammable or explosive gas and liquid.

The socket weld flange takes a 1 inch pipe inserted into its socket and joined by a fillet weld, which keeps the bore smooth and the joint strong. Forged stainless steel, a 150LB class and a raised face to ANSI B16.5 make it a standard fit for small bore process lines where leaks are not an option.

Name: Socket Weld Flange
Type: SW
Size: 1"
Pressure: 150LB
Material: Stainless Steel
Flange Face: RF
Standard: ANSI B16.5
Process Method: Forged
Usage: High temperature, high pressure, flammable or explosive gas or liquid occasions

Socket weld flanges earn their place wherever small lines run hot, tight or dangerous. The pipe seats in the socket before the fillet weld is made, so alignment is quick and the weld itself is external and easy to inspect. In refineries, gas processing and chemical plants, that adds up to less rework on tie-ins and a joint that crews can take apart for maintenance with standard bolting.

Selection is mostly about matching the line: confirm the 1 inch size and 150LB class against the pipe schedule and the adjoining flanges, then pick the gasket the medium demands. Installation follows the usual routine — insert the pipe, leave the small expansion gap the weld procedure calls for, complete the fillet weld, then bolt up the flanged side in a star pattern. Compared with a threaded joint, the socket weld route avoids leak paths through threads, which is exactly what flammable or explosive service asks for.

FAQ

Q1. Why socket weld rather than slip on or threaded here?

For a 1 inch line at 150LB carrying flammable or explosive media, the socket weld joint removes the thread leak path and gives a smooth internal bore. The fillet weld is external and inspectable, and the flanged side still opens for maintenance. Slip on works too, but socket weld is the tighter answer for small bore, high energy lines.

Q2. How does the pipe actually attach — is there a secret handshake?

No secret, just a socket. Slide the 1 inch pipe into the socket, set the small gap your weld procedure wants for expansion, and complete the fillet weld at the hub. The flange itself then bolts to its pair with the standard 150LB pattern, gasket in between, tightened evenly in a star pattern like any other flange joint.

Q3. Can I install it with a hammer and good intentions?

Keep the hammer in the toolbox. This is a pressure part on a line that may carry flammable or explosive media, so the weld must follow your qualified procedure and the bolting must be even and correct. Do that, and the flange rewards you with easy installation, easy disassembly and a seal that stays put.

Q4. What is the minimum quantity I can order?

Standard flange insulation gasket kits start at one set, and standard gaskets, studs, washers and sleeves start at one piece. Parts made to your drawing or to a non-standard bolt pattern are quoted one by one, because the minimum really depends on the material and the tooling involved.
