ERW vs LSAW vs SSAW: Quick Comparison Table
The table below summarizes how ERW, LSAW and SSAW differ across the factors that matter most when specifying pipe for a project — welding process, size range, pressure rating, cost and the standards each type typically meets. Use it as a quick reference, then check the sections and detailed guides below for the reasoning behind each figure.
| ERW | LSAW | SSAW | |
| Full name | Electric Resistance Welded Pipe | Longitudinal Submerged Arc Welded Pipe | Spiral Submerged Arc Welded Pipe |
| Weld shape | Straight seam | Straight seam | Spiral seam |
| Welding process | High-frequency induction/contact welding | Double-sided submerged arc welding (UOE/JCOE/HME) | Submerged arc welding, spiral forming |
| Raw material | Hot-rolled steel coil | Single medium/thick steel plate | Steel coil |
| Typical diameter | Small–medium | Large | Small–large (flexible) |
| Typical wall thickness | Thin | Thick | Medium |
| Dimensional accuracy | High | High | Moderate |
| Pressure resistance | Medium–high | High | Low–medium |
| Cost | Low | Higher | Lowest |
| Typical use | Urban gas, oil/product transport, structural | Long-distance oil & gas trunk lines, offshore, high-pressure | Water pipelines, piling, low-pressure/non-critical lines |
| Common standard | API 5L, ASTM A53 | API 5L PSL2, DNV | API 5L PSL1 |
How to Choose the Right Pipe Type
Need a large diameter, thick wall for high-pressure or long-distance oil/gas trunk lines → LSAW is the safer choice, and often the only compliant option for Class 1/2 pipeline areas.
Working with small-to-medium diameter, thinner-wall pipe for gas distribution or moderate-pressure service → ERW offers strong dimensional accuracy at a lower cost.
Prioritizing budget and need a wide range of diameters produced from the same coil → SSAW is the most economical, but limited to lower-pressure or non-critical applications (Class 3/4 areas).
Still unsure? Match your project's operating pressure, pipe diameter, and governing standard (e.g. API 5L PSL1 vs PSL2) against the comparison table above, or see the detailed pairwise comparisons below.
