ASME B36.10M

API 5L B steel pipe is a long steel strip with a hollow cross-section and no seams around it. It is made of carbon steel. Carbon steel is an iron-carbon alloy with iron as the matrix and carbon as the main added element. Carbon steel pipe has high strength and can withstand certain pressure and tension.

API 5L galvanized pipe is a pipe with a layer of zinc on the surface of the steel pipe. The presence of the zinc layer gives the galvanized pipe good corrosion resistance. The chemical properties of zinc are more active than iron. In a corrosive environment, zinc will oxidize before iron, thereby protecting the steel pipe matrix from corrosion.

A106 seamless steel pipe is a seamless steel pipe produced in accordance with the American Society for Testing and Materials (ASTM) standard A106. This standard specifies the material, size, manufacturing process, mechanical properties and other requirements of steel pipes, aiming to ensure the quality and reliability of steel pipes in various industrial applications.
