Threaded Flanges

Our range of threaded flanges and NPT flanges are manufactured as per international quality standards and is available in various dimensions. Our threaded flanges are used with their main advantage being that they can be used for extraordinary circumstances and in highly volatile areas where welding is hazardous. Our NPT threaded flanges can attached to the pipe without welding. These are low maintenance threaded flanges made from high quality raw material, that are available at fair prices. We ensure timely delivery of the products within stipulated time frame.
