2. Characteristics of API 5L GRB pipeline seamless steel pipe
API 5L GRB pipeline seamless steel pipe has the characteristics of high strength, high toughness, good weldability and corrosion resistance. The steel used has undergone special smelting and rolling processes, which greatly improves the mechanical properties of the steel pipe. At the same time, the inner and outer walls of the steel pipe are precisely processed and treated to ensure its good corrosion resistance and service life.
3. Production process of API 5L GRB seamless steel pipe
The production process of API 5L GRB seamless steel pipe mainly includes steelmaking, rolling, heat treatment, steel pipe forming, steel pipe processing and other steps. Among them, steelmaking is the basis for producing steel pipes. By controlling the composition and smelting process of steel, the quality and performance of steel are guaranteed. Rolling is to form the refined steel through a rolling mill to obtain the initial form of the steel pipe. Heat treatment is to improve the organizational structure and performance of the steel pipe by heating, heat preservation and cooling the steel pipe. Steel pipe forming is to further process and treat the rolled steel pipe to obtain the required steel pipe size and shape. Finally, steel pipe processing is to cut, bevel, rust remove and other treatments on the steel pipe to make it meet the use requirements.
