API 6A Flanges

The American Petroleum Institute or as shortened as API has developed specification api 15k flanges 6A, which is further categorised into two product specification levels i.e PSL 1 and PSL 2. While PSL 1 is a standard for quality, the api 6a flanges produced under PSL 2 has a very stringent testing method and adherence policy.  For instance the api 10000 psi flanges PSL 2 needs to conform to the following parameters i.e. qualification, temperature, design, specification,  process, hydrostatic test, and also inspection. Leading Manufacturer and Supplier of API class 10000 Blind Flange in India
