Socket Weld Alloy Steel Flange SW Wear Resistant F1 For Petroleum
A socket weld alloy steel flange is a type of flange that is designed to be welded onto a pipe with a socket connection. These flanges are typically used in high-pressure applications where corrosion resistance and strength are crucial. Socket weld flanges are connected to the pipe by inserting the pipe into the socket end and then applying fillet weld around the joint area.
Alloy steel flanges are made from a variety of alloy steel materials that provide enhanced properties such as high strength, corrosion resistance, and heat resistance. These flanges are commonly used in industries such as oil and gas, chemical processing, and power generation where high temperatures and pressures are present.

Flange Type: Socket Weld (SW)
Socket Weld flange
Socket Weld flanges were initially developed for use on small-size high pressure piping. Their static strength is equal to Slip On flanges, but their fatigue strength 50% greater than double-welded Slip On flanges.
The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.
ASME B31.1 1998 127.3 Preparation for Welding (E) Socket Weld Assembly says..In assembly of the joint before welding, the pipe or tube shall be inserted into the socket to the maximum depth and then withdrawn approximately 1/16" (1.6 mm) away from contact between the end of the pipe and the shoulder of the socket.
