Blind Flanges

Commonly referred as blanking flanges, Blind pipe flanges are widely used in high pressure applications. Blind flanges are generally used to seal the end of a piping system to prevent flow of liquids or gases. The use of blind flanges allows ease of access to a piping system once it has been closed. Our blind flanges are available with raised or RTJ faces and also with female threads. Blind flanges can be supplied with or without hub as per the customer requirements. We offer blind plate flanges manufactured at our facility to companies in various industries including shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants and turnkey projects among others.
