The company has focused on the research, development and production of high pressure, high and low temperature bolts and nuts for 13 years. Committed to coating technology for various harsh environments and media, we produce coating products to meet the anti-corrosion, acid and alkali resistance requirements of bolt fasteners, making them widely used in highly corrosive and harsh environments such as pressure vessels, high and intermediate pressure pump valves, petroleum drilling and production equipment, petrochemical devices, petrochemical pipeline containers, oil well production, and seawater/water injection sewage pipelines.
