Hot-rolled carbon steel pipe is a basic material widely used in construction, machinery manufacturing, petrochemical and other industries. It uses carbon steel as the main raw material and is formed by hot rolling process. It has good mechanical properties and processing characteristics and is suitable
Cold-rolled carbon steel pipe is a carbon steel pipe product produced by cold rolling process. It has high precision and surface quality and is suitable for precision machinery, automobile manufacturing, construction and furniture industries. Compared with hot-rolled steel pipe, cold-rolled steel pipe has higher dimensional
Carbon steel pipes are widely used in the fields of oil, natural gas, chemical industry, electric power, etc., and are often in harsh environments such as humidity, corrosive gases, groundwater, etc. In such an environment, carbon steel pipes are susceptible to corrosion, which shortens their
Seamless pipe is an important pipe widely used in various industrial and engineering fields. Its excellent performance makes it outstanding in pressure bearing and corrosion resistance. The diameter and wall thickness of seamless pipe are important parameters that determine its application range and applicable scenarios.
Honed tube is a high-precision steel tube used in hydraulic and pneumatic systems. It is widely used in oil cylinders and cylinders of various mechanical equipment. Due to its high finish and precise dimensional control on the inner surface, the honed tube plays an important
Welded pipe, also known as welded steel pipe, is a type of steel pipe that is formed by bending steel plates or steel strips into shapes and then connecting them into pipes through welding processes. It is a type of steel pipe widely used in
