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.

Moreover, PSL 2 flanges demanded traceability until all the examinations have been cleared by the specification. Industries that use the API Flanges Dimensions include petroleum, petrochemical along with the natural gas industry as well as the drilling and manufacture equipment for offshore piping systems. Dinesh Industries is API 6a Type 6bx Flanges Manufacturer. Generally, the api 6a flanges material used to produce them include carbon steel, alloy steel, stainless steel, duplex and super duplex stainless steel grades as well as Inconel and Hastelloy.
