51 steel pipe network to release the latest knowledge of thin-walled seamless steel tubes thin-walled seamless steel pipe is made of steel ingots or solid billets made of perforated, and then hot-rolled, cold-rolled or cold dial made of material is divided into ordinary tube, alloy tube . Divided into structural seamless steel tubes according to the purpose; seamless steel tubes for transportation; seamless steel tubes for boilers; high-pressure seamless steel tubes for boilers; high-pressure seamless steel tubes for fertilizer equipment; seamless steel tubes for geological bricks exploration; Seamless steel pipe; seamless steel pipe for oil cracking; seamless steel pipe for shipbuilding; cold-drawn cold-rolled precision seamless steel pipe; The material is divided into 10 #, 20 #, 35 #, 45 # 16Mn, 27SiMn, 12Cr1MoV, 10CrMo910, 15CrMo, 35CrMo and so on.
Structural Stainless Steel Seamless Steel Tube (GB/T14975-1994) is a hot rolled stainless steel used for corrosion resistant pipes and structural parts and parts widely used in the chemical, petroleum, textile, medical, food, and machinery industries. Expanded) and cold drawn (rolled) seamless steel tubes.
Stainless steel seamless pipe for fluid transportation (GB/T14976-1994) is a hot rolled (extruded, expanded) and cold drawn (rolled) seamless steel pipe made of stainless steel for conveying fluid.
Shaped seamless steel tubes are the general term for seamless steel tubes of other cross-sectional shapes than circular tubes. According to the different shapes and sizes of steel pipe sections, they can be divided into equal-wall thickness special-shaped seamless steel pipes (code D), unequal wall thickness profiled seamless steel pipes (codenamed BD) and variable-diameter special-shaped seamless steel pipes (coded as BJ). Shaped seamless steel tubes are widely used in various structural parts, tools and mechanical parts. Compared with round tubes, shaped tubes generally have larger moments of inertia and section modulus, and have greater resistance to bending and torsion, which can greatly reduce the structural weight and save steel.
Steel pipe specification: outside diameter * wall thickness (mm)
Steel pipe weight calculation formula: [(outer diameter - wall thickness) * wall thickness] * 0.02466 = kg/meter (weight per meter)
