Socket Weld Raised Face Flanges contain a shoulder on the inside of the flange that acts as a guide to set the depth at which the pipe is welded to the flange. They are typically used on smaller sizes of high-pressure pipes. These flanges are attached by inserting the pipe into the socket end & applying a fillet weld around the top. Raised Face Socket Weld Flanges allow for a smooth bore & better flow of the fluid or gas inside of the pipe. In addition, the gap at the end of the pipe prevents stress failure. These flanges can be used in various applications, from chemicals to power generation. It also offers excellent strength and resistance to leaks.
Socket Weld Pipe Flanges are typically provided with a raised face, flat face, or RTJ facing. Duplex Steel Socket weld raised face flanges are fabricated by inserting the pipe end into the flange until it bottoms out against the shoulder, & then retracting the pipe before welding it in place. Flat Face Socket Weld Flanges are generally made from stainless steel and come in various pressure ratings. There are many benefits to socket weld flanges, including that they are easily welded and durable. Like slip-on flanges, socket weld flanges are commonly used for small-diameter pipes. Therefore, they are ideal for applications that require small spaces.
Super Duplex Steel Socket Weld Flanges were originally used to reduce cracking due to thermal stresses in stainless steel superheaters. In these flanges, the lighter the pipe is, the larger the bore, conversely, the heavier the pipe is, and the smaller the bore, they are normally used for high pressure, cold or hot temperature. Nickel Alloy Socket Weld Raised Face Flanges are well suited for equipment handling hydrochloric acid in all concentrations and temperatures.
