| High Light | ERW Welded Boiler Tube ，A178-A Resistance Welded Pipe ，Low Pressure Boiler Economical | ||
The A178-A ERW boiler tube is a cost-effective electric resistance welded carbon steel tube manufactured to ASTM A178/A178M Grade A specifications. With full body normalizing after welding, it provides uniform mechanical properties ideal for low to medium pressure boiler applications where seamless tube economics are prohibitive.
| Standard | ASTM A178/A178M Grade A |
| Chemistry | C: 0.18 max, Mn: 0.27-0.63, S: 0.035 max, P: 0.035 max |
| OD Range | 12.7mm - 127.0mm |
| WT Range | 1.2mm - 8.0mm |
| Tensile Strength | ≥ 325 MPa |
| Yield Strength | ≥ 180 MPa |
| Max Working Pressure | Up to 350 psi (24 bar), application dependent |
Low-pressure steam boilers, hot water boilers, economizer sections, fire-tube boiler tubes, waste heat recovery units under 350 psi design pressure, and general heat exchanger tube bundles where seamless-grade tube cost is not justified by operating conditions.
