Carbon Steel Socket Weld Flanges Stainless Steel Forged Flange b16.5

A socket weld flange is a type of pipe flange that attaches to a pipe via a welded-in socket. The term “socket weld” refers to the method of attaching the two components, as well as the type of connection between them. Socket welds are typically used for smaller-diameter pipes and high-pressure applications.


Socket weld flanges are a type of pipe flange that is attached to a piping system by inserting a pipe into a recessed area of the flange. This allows for a smooth transition between the flange and the pipe and provides greater structural integrity to the piping system. Socket weld flanges are typically used in high-pressure applications, such as the transportation of oil and gas. Carbon steel is a common material for socket weld flanges, as it is strong and durable. However, carbon steel can corrode in certain environments, so it is important to choose the right material for the application. Stainless steel or nickel alloys are often used in corrosive environments. When selecting a socket weld flange, it is important to consider the size and pressure rating of the flange, as well as the materials compatible with the fluid being transported.
