What is EFW Pipe?
The EFW Pipes are made of various grades of stainless steel and they are manufactured through the electric welding procedure. The process involves passing high voltage electricity onto the material, which helps to heat and melt it. These pipes are available in seamless, heavily cold-worked welded, and straight-seam welded variants. These pipes are mostly used for applications taking place in high temperature and corrosive environments. Different surface finishes can be customized on these pipes, like black finish or galvanization, depending on the requirements.
What is Electro Fusion Seam Welded Steel pipe (EFSW)?
The Electro Fusion Seam Welded Steel pipe (EFSW) is basically manufactured by the process of fusion welding. The whole procedure depends on the melting of the material which helps to join the plate of a similar melting point and composition. It is popularly known as continuous welding; this is because the material is made from coiled steel that has required thickness and weight, along with the needed diameter. These pipes are basically made from rolling the plates and then the seams are welded. After this, a scarfing procedure is conducted on the pipes to give them a good surface finish. Depending on the requirements, different grades of stainless steel can be used for manufacturing the pipes.
Features of Stainless Steel EFW Pipe?
The Stainless Steel EFW Pipe is made using the electric fusion welding procedure which eliminates the necessity of other welding materials for manufacturing the pipe through the welding procedure. One of the best things about the Stainless Steel EFW Pipe is that as there are no other materials involved, the sizes of these pipes can range between 6” to 100” in diameter. Different grades of stainless steel can be used for manufacturing pipes using this procedure.
Being resistant to corrosion, these pipes are used in industries like petrochemical, textile, food processing, and many more. Different schedules of these pipes can tolerate different pressure levels.
