A106B A53 S45C A333GR.6 thick wall steel pipe quality assurance
The production process of thick-walled seamless steel pipes can be divided into four basic methods: cold drawing, cold rolling, hot rolling, and thermal expansion. Uses are divided into seamless steel pipes for structure; seamless steel pipes for transportation; seamless steel pipes for boilers; high-pressure seamless steel pipes for boilers; high-pressure seamless steel pipes for fertilizer equipment; seamless steel pipes for geological drilling; seamless steel pipes for oil drilling; Seamless steel pipes for petroleum cracking; seamless steel pipes for ships; cold-drawn cold-rolled precision seamless steel pipes; various alloy pipes. Seamless steel pipes are expressed in terms of outer diameter and wall thickness. Thick-walled seamless steel pipes are mainly used for machining, coal mines, hydraulic steel, and many other purposes.
Hot-rolled thick-walled seamless steel pipes, cold-rolled thick-walled seamless steel pipes, cold-drawn thick-walled seamless steel pipes, extruded thick-walled seamless steel pipes, and stainless steel seamless steel pipes for pipe jacking structures (GB/T14975-2002) are used for Seamless steel pipes of general structure and mechanical structure are widely used in the hot-rolled (extruded, expanded) and cold-rolled (extruded, expanded) and cold-rolled stainless steel of corrosion-resistant pipes and structural parts and parts in the chemical, petroleum, textile, medical, food, machinery and other industries. Drawing (rolling) seamless steel tubes.
Stainless steel seamless steel pipes for fluid transportation (GB/T14976-2002) are general seamless steel pipes used to transport water, oil, gas and other fluids. They are usually hot-rolled (extruded, expanded) and cold drawn (rolled) made of stainless steel. ) Seamless steel pipe.
Shaped seamless steel pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. According to the different shape and size of the steel pipe section, it can be divided into equal wall thickness special-shaped seamless steel pipe (code D), unequal wall thickness special-shaped seamless steel pipe (code BD), variable diameter special-shaped seamless steel pipe (code BJ). Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have larger moments of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce structural weight and save steel.
Seamless steel pipe for structure (GB/T8162-2008) is a seamless steel pipe used for general structure and mechanical structure.
