Low-Temperature Carbon Steel Ventilation Valve

In the petrochemical industry, WCC (ASTM A216 Grade WCC) has become the core material for transporting oil, gas and steam media due to its characteristic of adapting to working conditions ranging from -29℃ to +425℃. In the manufacturing of valves for crude oil transportation pipelines, WCC can withstand a working pressure of 4-10MPa and a medium temperature of 350℃. Its uniform organizational structure can prevent local wear caused by medium erosion. After precise processing of the valve sealing surface, the leakage rate is controlled at ≤1×10⁻⁶MPa·m³/s, meeting the strict sealing requirements of the petrochemical industry. In the steam system of the oil refinery, the high-pressure pump casing made of WCC material can withstand a saturated steam pressure of 425℃ for a long time. The impact resistance endowed by manganese element can cope with the mechanical shock caused by steam pressure fluctuations and prevent the pump casing from cracking. Meanwhile, WCC has certain corrosion resis…
