JIS Certified SSAW Weathering Steel Spiral Welded Pipe

JIS Certified SSAW Weathering Steel Spiral Welded Pipe｜Rigorous Standards for Century-Durable Engineering Pipes

JIS Authoritative Certification + Weathering Steel Material + SSAW Spiral Welding Technology, triple guarantee to provide high corrosion resistance, high strength, high stability pipe solutions for harsh environments such as outdoor, marine, municipal, energy, etc., suitable for high-end engineering markets in Japan and globally.

★  JIS Standard Endorsement, Globally Recognized Quality

Strictly comply with Japanese industrial standards such as JIS G3125 SPA-H, with full-process control from chemical composition, mechanical properties to dimensional tolerances. Passed ultrasonic/ray non-destructive testing to ensure stable performance and strong interchangeability of each pipe, easily meeting access requirements for high-end projects in Japan, Southeast Asia and internationally.

★  Weathering Steel Material, Maintenance-Free Long Service Life

Adopt SPA-H weathering steel, which naturally forms a dense oxide protective film on the surface. Its atmospheric corrosion resistance, salt spray resistance and aging resistance far exceed ordinary carbon steel. No frequent coating maintenance is required in outdoor/marine environments, greatly reducing life-cycle costs and extending service life by 3-5 times.

★  SSAW Spiral Welding, Large Diameter & High Strength

Adopt double-sided submerged arc spiral welding process, capable of producing large-diameter steel pipes with outer diameter 219-3000mm. The spiral weld structure enhances overall rigidity and deformation resistance, with excellent pressure bearing, bending resistance and impact resistance, suitable for heavy-duty scenarios such as bridge pile foundations, port terminals, oil and gas transmission, wind power foundations.

★  Complete Specifications & Customizable, Adapt to Diverse Scenarios

Stock 6m/12m standard lengths, support custom length, bevel, anti-corrosion coating (3PE/FBE/epoxy zinc-rich), meet all-scenario requirements of fluid transportation, structural support, pile pipes, municipal pipe networks, etc., adapt to international standards such as EN, ASTM, API, one-stop solution to project procurement problems.

★  Source Factory, Double Guarantee of Cost-Effectiveness & Delivery

Own production line, strict cost control, highly competitive price; spot stock + rapid production scheduling, regular orders delivered in 15-21 days, support small-batch trial orders and large-batch stable supply, provide technical support and after-sales guarantee throughout the process.
