5. Remarks
-
Welding Preparation: Valve ends are machined with bevels according to ASME B16.25 or customer drawings. Installation must be performed by qualified welders following the approved welding procedure.
-
High-Temperature Strength: WC6 material offers excellent high-temperature creep resistance and hydrogen attack resistance, making it suitable for high-pressure steam and petroleum pipelines.
-
Seal Surface: The sealing surfaces are typically hardfaced with Cobalt-based alloy (Stellite) to ensure a long service life under high-temperature and high-pressure conditions.
Note: The information above is compiled based on general industry standards and technical data from various manufacturers. For specific projects, especially those with demanding conditions, it is recommended to consult the valve manufacturer for detailed drawings, torque values, and CV values.
