ASTM A213 T91, T12, T11 alloy pipe is a ferritic and austenitic alloy steel seamless steel pipe used in boilers, superheaters and heat exchangers.

Welded steel pipes are made by rolling steel plates or steel strips into tube shapes and welding them through a welding process. According to its weld form, it can be divided into straight seam welded pipe and spiral seam welded pipe.

S355J2H is a low-alloy structural steel pipe with excellent mechanical properties and reasonable chemical composition. It is often used to manufacture pressure vessels, transmission pipelines and various engineering machinery.

A209 alloy pipe is an American standard alloy steel pipe. It not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness, high and stable long-lasting plasticity and thermal strength properties.
