Thick-walled seamless pipes are produced through cold drawing and hot rolling, with materials categorized as ordinary pipes and alloy pipes. They are classified by application into structural seamless steel pipes; transport seamless steel pipes; boiler seamless steel pipes; high-pressure boiler seamless steel pipes; high-pressure seamless steel pipes for fertilizer equipment; seamless steel pipes for geological brick exploration; seamless steel pipes for oil brick exploration; oil cracking seamless steel pipes; ship seamless steel pipes; cold-drawn and cold-rolled precision seamless steel pipes; various alloy pipes.

Thick-walled Seamless Steel Pipe Categories - Hot-rolled Thick-walled Seamless Pipe, Cold-rolled Thick-walled Seamless Pipe, Cold Drawn Thick-walled Seamless Pipe, Extruded Thick-walled Seamless Pipe, Jacking Pipe.

Steel pipe weight calculation formula: [(outer diameter - wall thickness) * wall thickness] * 0.02466 = kg/m (weight per meter).

Wall thickness seamless steel pipe theoretical weight calculation formula: (Outer diameter - Wall thickness) × Wall thickness × 0.02491 = KG/M (weight per meter).

Alloy steel thick-walled seamless tube theoretical weight calculation formula: (Outer Diameter - Wall Thickness) × Wall Thickness × 0.02486 = KG/M (weight per meter).
