| Pipe Type / Primary Manufacturing Method | Key Characteristics & Typical Applications | Key Applicable Standards & Specifications |
|---|---|---|
| SEAMLESS STEEL PIPE (Hot-Finished / Cold-Drawn) |
Process: Pierced billet, no weld seam. Uniform structure, higher pressure rating. Applications: High-pressure/temperature systems, critical process lines, instrumentation, hydraulic systems, OCTG, mechanical tubing. Key Feature: Homogeneous circumference, better for bending/swaging. |
Dimensional & Material:
|
| WELDED STEEL PIPE - ERW (Electric Resistance Welded) |
Process: Formed strip, weld by electric resistance. Weld seam is heat-treated. Applications: Medium-pressure fluid transport, structural applications, fencing, lower-pressure process lines, oil & gas gathering lines. Key Feature: Cost-effective, good dimensional consistency. |
Dimensional & Material:
|
| WELDED STEEL PIPE - SAW (Submerged Arc Welded) |
Process: Longitudinal (LSAW) or Spiral (HSAW/SSAW). Uses granular flux. Applications: Large diameter pipelines (oil/gas/water transmission), piling, structural columns, wind turbine towers. Key Feature: Large diameters (>24"), high strength, for major projects. |
Dimensional & Material:
|
| WELDED STEEL PIPE - HFW (High Frequency Welded) |
Process: Similar to ERW but uses high-frequency current. Finer weld, better quality. Applications: Precision mechanical tubing, automotive components, furniture, medium-pressure hydraulic lines, API line pipe. Key Feature: Clean weld, good for further processing (galvanizing, bending). |
Dimensional & Material:
|
| WELDED STEEL PIPE - CW (Continuous Welded - Furnace Butt Weld) |
Process: Older method, heated strip ends pressed together. Applications: Low-pressure plumbing, heating, fencing, low-criticality fluid conveyance. Key Feature: Lowest cost, not for high pressure or bending. |
