Seamless steel pipe is a steel pipe without weld, made of round steel perforation. According to the production method, the seamless steel pipe is divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold-drawn seamless steel pipe, extruded seamless steel pipe, etc. The maximum size of seamless steel pipe can be 900mm, the minimum size is 4mm. According to the different use, the wall thickness of seamless steel pipe is not the same. Seamless steel pipe is mainly used in petroleum geological drilling pipe, petrochemical cracking pipe, boiler pipe, bearing pipe and high-precision structural steel pipe for automobiles, tractors and aviation.


Production Process of Seamless Steel Pipe: Hot Roll Draw and Cold Roll Draw

  • Hot-Rolled Seamless Steel Pipe Production Process: Tube preparation and inspection, Tube Heating, Perforation, Rolling, Tube Reheating, Sizing, Reducing, Heat Treatment, Finished Pipe Straightening, Finishing, Inspection, etc. The Outer Diameter of the Hot-Rolled Seamless Steel Pipe> 32mm, Wall Thickness is between 2.5-200mm.
  • Cold-Rolled (Drawing) Seamless Steel Pipe Production Process: Billet Preparation, Pickling Lubrication, Cold Rolling (Drawing), Heat Treatment, Straightening, Finishing, Inspection, etc. The production process of Cold-Rolled Seamless Steel Pipe is relatively complex, Outer Diameter can be 6mm,Wall Thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, the wall thickness is less than 0.25mm.
  • Cold Rolling has Higher Dimensional Accuracy than Hot Rolling

Feature:

  • Excellent mechanical properties: seamless steel pipe overall strength, toughness and impact resistance is excellent, can withstand high pressure, such as oil pipeline, high-pressure boiler pipeline, long-term stable operation in high-pressure environment, not easy to break and damage.
  • High accuracy: Accurate tolerance control of outer diameter and wall thickness. Ensure consistency of steel pipes in the same batch
  • Corrosion resistance: After the steel pipe material itself and the subsequent anti-corrosion treatment, the corrosion rate is slow and the service life is long when it comes into contact with corrosive media such as acid, alkali and salt water in the field of chemical industry and Marine engineering

Standard:

ASTM A269, ASTM A213, ASTM A789, ASTM A334, ASTM A179, ASTM A192, ASTM A790, ASTM A335, ASTM A199, ASTM A210, ASTM A312, ASTM B-111,ASTM B167


Application:

  • Oil and Gas industry: oil and gas Wells (subject to high pressure and high temperature environments)
  • Chemical industry transport chemical raw materials and chemical products (good corrosion resistance)
  • Manufacturing machine parts and auto parts (withstand high strength and high pressure environments)
  • Construction industry Structure and bridge construction, withstand weight and stress 5.Oil drill pipe, car drive shaft, bicycle frame and construction
