A professional supplier of pipeline fittings, including steel backing rings, PVC pipes, fittings, and valves. Products are widely used in water supply, chemicals, water treatment, oil & gas, environmental protection, pharmaceuticals, and mining industries. The company follows a strict quality-first and customer-oriented approach, operating under ISO9001 standards with advanced production facilities, standardized workshops, and comprehensive testing systems to ensure high-quality and cost-effective products for global customers.

A full range of pipeline fittings is available for one-stop procurement, including flanges, steel backing rings, PVC pipe nipples, equal and reducing tees, ball valves, couplings, reducers, end caps, and 45°/90° elbows, covering sizes from DN63 to DN1200 and standards such as SDR11 and SDR17. Steel backing rings are essential components used to connect pipes and equipment, typically working with PVC pipe nipples to ensure secure, leak-free, and stable pipeline connections, especially in medium- and high-pressure systems.

Function

The core function of steel backing rings is to achieve precise sealing through bolt tightening, effectively preventing leakage of gases, liquids, and other fluids. The sealing mechanism relies on pre-drilled holes in the flange, where bolts are inserted and tightened to ensure a tight connection between two flanges. The addition of a sealing gasket further enhances sealing performance, allowing the pipeline system to remain secure and reliable even under high-pressure and complex working conditions, preventing resource loss and safety risks.

Another key advantage is easy operation. No complex tools are required—tightening or loosening bolts allows for quick installation or disassembly of pipelines, making it especially suitable for emergency maintenance. This simple and efficient process significantly reduces construction and repair time, lowers maintenance difficulty and labor costs, and improves overall engineering efficiency.
