Useful Information Carbon Steel Flanges

Flanges are commonly used to connect valves into pipework making it easier for removal and maintenance. There are many common flange standards and flanges within the same standard can either be flat (commonly cast iron, ductile iron) or raised face (commonly cast steel and stainless steel). Below is a reference table for critical flange dimensions to help identify what standard you have.
