SSAW Spiral Steel Pipe — The Core Product
Spiral submerged-arc welded (SSAW) pipe is our flagship product, accounting for 60% of mill capacity. The spiral forming process delivers consistent weld quality across the full diameter range from 219mm to 3048mm.
Manufacturing Standards
- SY/T 5037-2023 — spiral welded pipe for water supply, gas and piling
- GB/T 9711-2023 — steel pipe for pipeline transportation (PSL1/PSL2)
- API 5L — line pipe to American Petroleum Institute specification
In-House Anti-Corrosion Coating
Every pipe can be coated before it leaves the yard — 3PE anti-corrosion, epoxy, or plastic coating for potable water service. No third-party coating, no extra lead time.
Quality Control
100% of welds are UT or RT tested; hydrostatic testing to standard pressure; mill test certificates issued with every batch. Third-party SGS/BV inspection welcome before loading.
