What Is API 6A Flange
Since they are used in high pressure and high temperature systems, the Carbon Steel API 6A 5000 Flange is common in this range. The compact flanges come in two pieces and are tightened together with bolts and nuts to get maximum grip and tightness at connections. Since these are used in the highly sensitive offshore industries, these are very highly corrosion resistant and strong. The API 6a Blind Flange is used to terminate the end of piping in the offshore oil and gas industries. The API 6a Weld Neck Flange Dimensions allow the weld neck flanges to be installed in with high stress pipe systems with high accuracy. Our Api 6a 6b And 6bx Flanges Sizes vary according to the customer needs and we supply all sizes of flanges. Please contact us with your requirements or inquiries.

Difference Between Api 6a Blind And Api 6a Bx Flange
The API 6a is a specification by the American Petroleum Institute. The blind flanges are used to terminate a connection completely and are not connected to more pipes. The bx flanges are ring type joint flanges which are connected to two pipes. The bx flanges do not stop the flow of fluid either liquid or gas whereas the blind flanges do stop the flow. The ring type joint flanges are easy to install and have a high efficiency of sealing the connections in a line. The blind flanges are used to terminate the flow or pipeline.
