EN 10216-1 P235 Steel Pipe
EN 10216-1 P235 steel pipe is a European standard specification for seamless steel tubes for pressure purposes, specifically focusing on non-alloy and alloy fine grain steels. EN 10216-1 P235 steel pipe is generally made from low carbon steel grades such as P195, P235 and P265 which are known for their weldability and toughness. These pipes are produced through a seamless manufacturing process without any welding. This method ensures that the pipes have a uniform structure and are suitable for high pressure applications.
