GRP Flange Manufacturers
D Chel oil and gas is one of the most leading GRP (Glass Reinforced Polyester) Flanges Manufacturers in India. GRP Flanges have a high and consistent quality is achieved and guaranteed by combining advanced manufacturing techniques such as Resin Transfer Moulding (RTM), Vacuum Injection (VI), and Compression Moulding (hot pressing) with Precision Tape Winding and CNC machining. We have available types of flanges, such as collar bushes, stub flanges, backing rings, fixed flanges and blind flanges according to different standards, including EN 1092-1 (formerly DIN 2501), ASA, ANSI, AWWA, and others. The GRP Flanges are available in a variety of styles and diameters, ranging from 15 mm to 2,500 mm, with pressure levels up to and including 70 bar (1,000 psi). We are also known as the Leading Manufacturers of GRP Fitting, and so on.
