No-Weld Connections for Steel Pipes
The Steel Pipe Universal Connector is for quick steel pipe connections. Steel pipes are used in industrial water, fire protection, and heating systems. Traditional steel pipe connections use welding or flanges. Welding takes time and needs certified workers. Flanges need many bolts and gaskets. Our connector uses mechanical locking only. No welding, no flanges. The installation is fast and simple.
The connector bore and seal design match steel pipe ODs exactly. Steel pipes often have weld seams, zinc coatings, or anti-corrosion layers. Our gasket hardness is chosen carefully. It seals well against steel surfaces. But it does not damage coatings. The connector allows some axial movement and angular deflection. This gives steel pipe systems flexibility and reduces stress points.
Our factory is 3,500 square meters. We have a full production line from casting to assembly. We hold ISO 9001 certification. Our quality process includes raw material inspection, in-process checks, and final testing. We have calipers, thread gauges, hardness testers, and hydrostatic test machines. Our annual sales exceed 80 million RMB. Our products serve a wide market.

Used in a Large Commercial Complex
A large commercial complex needed fire protection pipe installation. The building had limited space. Welding was not allowed. The contractor used our Steel Pipe Universal Connector. They completed all steel pipe connections mechanically. The system passed the fire inspection. It held 1.4 MPa for two hours with no leakage.
We offer a 10-year warranty. The epoxy coating is hard and scratch-resistant. It looks good for exposed installations. The bolts have anti-loosening washers for vibration resistance. The product comes with installation instructions. Any pipe worker can learn it quickly.
