  Application:

  Smls Steel Pipe is a kind of economic section steel, which plays an important role in the national economy. It is widely used in petroleum, chemical industry, boiler, power station, ship, machinery manufacturing, automobile, aviation, aerospace, energy, geology, construction and military industry.

  classification:

  ① According to the section shape: round section pipe, special section pipe

  ② By material: carbon steel pipe, alloy steel pipe, stainless steel pipe, composite pipe

  ③ According to the connection mode: threaded pipe, welded pipe

  ④ According to production mode: hot rolling (extrusion, jacking, expanding) pipe, cold rolling (drawing) pipe

  ⑤ According to usage: boiler pipe, oil well pipe, pipeline pipe, structural pipe, fertilizer pipe

  Production process of Smls Steel Pipe

  ① Main production process (main inspection process) of hot rolled Smls Steel Pipe:

  Tube blank preparation and inspection → tube blank heating → piercing → tube rolling → raw tube reheating → sizing (reducing) → heat treatment → finished tube straightening → finishing → inspection (nondestructive, physical and chemical, bench inspection) → warehousing

  ② Main production process of cold rolled (drawn) Smls Steel Pipe

  Blank preparation → pickling and lubrication → cold rolling (drawing) → heat treatment → straightening → finishing → inspection
