FRP GRP Flanges Manufacturers, Suppliers, Stockists in India.

D Chel Oil & Gas is one of the leading Manufacturers, Suppliers & Exporters of  FRP GRP Flanges in India FRP GRP Flanges (Perfluoroalkoxy) offers stress resistance and is used when more demanding mechanical characteristics are required. FRP GRP Flanges is the product of choice for applications involving extreme chemical resistance combined with high-temperature exposure. FRP GRP Flanges are preferred when additional clarity, flexibility, and a higher continuous service temperature are required. FRP GRP Flanges provides stiffness and long flex-life (up to 500º F) and has all the general properties of PTFE.

Our Flanges are of Type II construction, Mat plus alternating layers if 1 1/2 oz Mat and 24 oz are Woven per ASME RTP-1 table 2A2. This makes our flanges 1.7 times stronger in the critical flange and hub area than a typical Type I (all Mat) flange. We are also known as the Leading Manufacturers of FRP Sheets.
