Boiler Tube EN10216-2 P265GH Carbon Steel U TUBE For Boiler
EN10216-2 P265GH U tube is a type of seamless carbon steel tube that conforms to the European standard EN10216-2. This tube is made from P265GH steel, which is a non-alloy quality steel used for high-temperature service applications. The "U" shape of the tube allows for easy installation and connection in various piping systems. This type of tube is commonly used in power plants, boilers, and other industrial applications where high temperatures and pressure are present.
