| High Light | Stainless Steel ERW Welded Pipe ，ERW Welded Pipe Schedule 5S ，ERW Welded Pipe Schedule 40S | ||
The Stainless Steel ERW (Electric Resistance Welded) Pipe is manufactured by cold-forming stainless steel coils into a cylindrical shape and welding the longitudinal seam using high-frequency electric resistance welding technology. This process produces a pipe with a narrow, uniform weld seam that is virtually indistinguishable from the base metal after proper heat treatment. ERW pipes offer an excellent balance of corrosion resistance, dimensional accuracy, and cost-effectiveness, making them a popular choice for a wide range of industrial and commercial applications.

| Step | Description |
|---|---|
| 1. Coil Unwinding | Stainless steel coil is unwound and leveled |
| 2. Forming | Coil is gradually cold-formed into a cylindrical shape |
| 3. Welding | High-frequency electric current heats edges; pressure forges weld |
| 4. Seam Annealing | Weld seam is post-weld heat treated to relieve stress |
| 5. Sizing | Pipe passes through sizing rollers to achieve final dimensions |
| 6. Cutting | Pipe is cut to specified lengths |
| 7. Heat Treatment | Full annealing restores corrosion resistance |
| 8. Testing | Hydrostatic and eddy current testing performed |
| Parameter | Tolerance |
|---|---|
| Outer diameter (OD) | ±0.4 mm for OD ≤ 48.3 mm; ±0.8% for larger |
| Wall thickness | ±12.5% |
| Length (fixed) | +0 / -3 mm |
| Straightness | 0.2% of total length |
| Ovality | Within OD tolerance |
