Exploring for and extracting oil, gas and hydrocarbons is becoming increasingly difficult and dangerous. These challenges include workplaces that are more exposed than ever to high temperatures and hazardous chemicals, so cutting-edge materials knowledge combined with process technology solutions is essential.

Diwei Seal products for the petroleum and natural gas industry can ensure better sealing performance in the harsh environment of high pressure, intensive chemical corrosion. Years of cumulative research results have led to the development of a variety of specialized materials and designs for seal and bearing applications in this particular industry.

Diwei FFKM Perfluoroelastomers has better solvent resistance. Considering the use requirements of pressure and wear resistance, we designed and developed a variety of high-performance rubber products for petroleum exploitation. Diwei G175GFL is specially designed to meet the challenges of the harsher operating environments in the world.

In order to operate efficiently, the rubber sealing system we provide must be resistant to chemicals in harsh environments, including acid gases and extreme temperatures. Our standard and specialized sealing solutions include subsea, surface, downstream system lines, etc. Typical applications include wellhead couplings, load rotary valves, couplings, safety valve rubber/metal blowout seals, sampled low friction cylinder seals, etc. It also provides high molded oversized O-rings for large sized pipe joints, large water pumps and power engines.
