Socket Weld Alloy Steel Flange SW Wear Resistant F1 F5 F9 F11 F12
Alloy steel flanges are flanges manufactured from alloy steel materials, which are composed of multiple elements, including iron and carbon, as well as other alloying elements such as chromium, nickel, molybdenum, and vanadium. These alloys impart specific properties to the flanges, such as enhanced strength, corrosion resistance, and high-temperature capabilities.
Alloy steel flanges are available in various material grades, each with its own composition and properties. Common alloy steel grades used for flanges include ASTM A182 F5, F9, F11, F22, and F91. These grades offer different levels of strength, toughness, and resistance to corrosion and high temperatures.

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assembly of the joint before welding, the pipe or tube shall be inserted into the socket to the maximum depth and then withdrawn approximately 1/16" (1.6 mm) away from contact between the end of the pipe and the shoulder of the socket.
