Pipe Flanges

Changmao Valve Group

Product overview

Changmao lists several flange constructions and material choices; individual size, facing and standard must follow the selected flange rather than a range-wide assumption.

Specify the mating pipe or equipment connection, flange dimensions, material and service conditions. Ask for the proposed flange designation and drawing so its drilling, facing and attachment can be checked against the actual joint. Request the current catalogue or drawing for this item, and confirm the offered configuration and supporting documents with the company before specifying an order.
