Basically there are three types of High Temperature Steel Pipe:
High Temperature Carbon Steel pipe
High Temperature Alloy Steel pipe
High Temperature Stainless Steel tube
High Temperature Carbon Steel tube
High Temperature service tube are typically knows as heat exchanger tube, which operates at 400 degree Celsius to 1100 degree Celsius.
Steel GradeThere are various grades of steel to manufacture steel pipe for high temperatures service, such as ASTM A106,A179, A192, A210
Parameters of Steel Pipe for High heat Service
