API 6A Flanges
Dimensions of API 6a Blind Flanges and API 6B Flanges
API 6A flanges are ring type joint flanges that are made under the API 6A standards. R.C. Metal Corporation is a manufacturer and supplier of the API 6a Blind Flanges and other types. The 6A flanges have different specifications based on the pressure capacities. The blind flanges are used to close a pipeline. The API 6B Flanges have a pressure capacity of 2000psi and are of the lowest pressure capacity in this range of flanges. There are other grades such as the API 6bx flanges which has 2000psi pressure capacity as well but the design varies. The API 6A 10000 psi flanges is a high pressure rating flanges that is used in high pressure applications. The pressure capacities range from 2000psi through 20000psi.
API 6A Flanges
The API 5l Grade B Flanges can be made up of high alloys due to their higher pressure capacities. They have the advantage of tolerating high torque of the bolts when tightened with bolts and nuts. The API 6bx weld neck flanges has a welded neck in addition to add to the strength of the connection. The flange is sometimes connected with a API Companion Flanges that supports the installation of the 6A flanges. The material used for the different types of the 6A flanges range highly.
