ERW Steel Pipe DN350 ASTM A106 GR.C For Power Plant Water Systems

Engineered for the rigorous demands of power plant hydronics, Huayang's DN350 ASTM A106 Grade C pipes feature an elevated carbon profile (up to 0.35%) that significantly boosts mechanical strength over standard Grade B variants. This metallurgical advantage is vital for large-diameter water systems subject to high-pressure surges and thermal cycling. Each 355.6mm unit is produced via high-frequency ERW technology, followed by full-body heat treatment to normalize the weld zone and eliminate residual stresses. As a key supplier to the energy sector, Huayang subjects these pipes to stringent hydrostatic testing and ultrasonic flaw detection, ensuring a flawless internal surface that prevents cavitation and scale buildup. Our A106 Grade C conduits provide a robust, long-term solution for boiler feed lines and condenser cooling loops, meeting the highest safety benchmarks in modern power infrastructure.
