Product description

Highlights at a glance

  • Hot rolled heavy wall alloy seamless pipe with API, ISO & CE certificates, dense grain structure, high compression resistance, stable performance under ultra-high pressure and high temperature working conditions.
  • High-temperature hot rolled integrated forming, fully seamless structure without weld seam, thoroughly avoid leakage risk for heavy pressure fluid transportation and pressure vessel accessories.
  • Extra thick wall design provides powerful load capacity, strong resistance to external extrusion and impact, ideal tubing for underground pipelines and heavy engineering equipment.
  • Wide range of heavy wall and large diameter specifications, hard to be manufactured by cold drawing, meet customized demands of heavy-duty machinery and petrochemical equipment.
  • Support customized heat treatment such as tempering and normalizing, balance hardness and toughness, effectively prevent pipe rupture under alternating temperature and pressure cycles.
  • Premium alloy steel billets as raw material, spectral composition inspection before production, eliminate internal defects including cracks, slag inclusion to raise finished product yield.
  • Comply with EN, ASTM, GB, DIN international standards, complete mill test report supplied, support third-party inspection and smooth customs clearance for global export orders.
  • Uniform wall thickness after hot rolling, avoid partial stress concentration, improve overall structural safety when enduring internal pressure and external heavy load simultaneously.
  • Every batch carries out ultrasonic nondestructive testing to detect tiny internal flaws, guarantee safe long-term service in high-risk pressure equipment systems.
  • Factory direct supply without intermediate merchants, stable production capacity, flexible production scheduling to guarantee on-time delivery of bulk heavy wall pipe export orders.
