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.
Buying Guide: How to Request a Quote
For large diameter steel pipe projects, the more detail provided, the more
accurate our technical assessment. Please include:
Dimensions: Precise OD and Wall Thickness.
Application: Is it for piling (ASTM A252) or fluid transport (API 5L)?
Environment: Will the pipe be buried or underwater? (This determines the
coating type).
Delivery Site: Large pipes involve complex logistics; please specify the
destination port for a landed cost estimate.

Minimum Order: 5 tons
