Large Diameter SSAW Steel Pipes: Heavy-Duty Solutions for Global Infrastructure
40 Years of Industrial Heritage Precision Spiral Welding Diameters up to
3000mm+
When it comes to large-scale infrastructure—be it cross-country water
transmission, offshore piling, or high-pressure energy sectors—the integrity
of the piping is non-negotiable. At JSFITTINGS, we leverage four decades of
manufacturing expertise to produce Large Diameter SSAW (Spiral Submerged Arc
Welded) steel pipes that bridge the gap between cost-efficiency and
uncompromising structural strength.
Compliance & International Standards
Our Large Diameter SSAW pipes are engineered and tested to meet the world’s
most stringent regulatory requirements. We provide full MTC (Mill Test
Certificates) with every shipment.
Energy Sector: API 5L (PSL1 & PSL2) – Ensuring safety in oil, gas, and
hydrocarbon transport.
Structural & Piling: ASTM A252 & EN 10219 – Optimized for load-bearing
capacity in bridge and marine foundations.
Water Supply: AWWA C200 & DIN 2460 – Certified for municipal water pipelines
and irrigation systems.

Why SSAW for Large Diameter Projects?
Large diameter pipes can be produced via LSAW or SSAW. However, the Spiral
advantage offers distinct benefits for project managers:
Versatility in Sizing: We can produce a wide variety of large diameters from a
single width of steel strip, allowing for faster production cycles.
Increased Rigidity: The spiral weld seam acts as a structural reinforcement,
providing superior resistance against internal pressure and external crushing
loads.
Cost-Efficiency: For diameters exceeding 800mm, SSAW typically offers a more
economical solution without sacrificing the mechanical properties required for
heavy-duty use.

Industry Applications
Our ssaw steel pipes serve as the “arteries” of industrial development across
various sectors:

Marine & Foundation Piling: High-strength steel casing for bridges, piers, and
skyscrapers.
Low-Pressure Fluid Transport: Reliable main lines for municipal water, sewage,
and drainage.
Hydroelectric Power: Penstocks and cooling water circulation systems.
Dredging Operations: High-diameter pipes for sand and slurry transport in
coastal reclamation.
The 40-Year Advantage: Why Engineers Trust JSFITTINGS.
