In the steel pipe industry, ERW (Electric Resistance Welded) high-frequency welded pipes and seamless steel pipes are two common product types. They have some obvious differences in production technology, performance characteristics and scope of application.Of course, ERW (resistance welding) high-f

Large-diameter square pipes can be manufactured using direct forming technology (DFT), where the pipes are formed directly, or through the tube mill of converting round pipes to square pipes (FFX). Additionally, in some cases, they can be produced by pushing round pipes into square ones using a Turk

As a versatile equipment for producing high-frequency welded pipes, tube mills are capable of manufacturing various types of steel pipes, including square pipes, round pipes, and profiles. They are also suitable for processing a variety of materials such as carbon steel, stainless steel, galvanized
