Technical Specifications

China ASME B16.5 Welding Neck Flanges:

Dimension B corresponds to the pipe inside diameter.Values quoted assume 40S/Standard wall thickness.
Weights are based on manufacturer’s data and are approximate.
Flat face flanges may be provided at full thickness,C,or with raised face removed (the latter is nonstandard).
