Replace Damaged Pipe Sections Quickly
The Double Socket Repair Coupling is made for replacing short damaged pipe sections. When a pipe section has rust holes or cracks, you cut out the bad part. Then you install new pipe in its place. Traditional methods need multiple fittings and precise measurement. Our coupling has two sockets integrated into one housing. The distance between the sockets matches the removed section length. You just insert both pipe ends and tighten.
The socket spacing is custom-made based on your damaged section length. The two sockets connect the old pipe ends and the new pipe section in one step. There are fewer connection points. This means fewer potential leak points. The one-piece design improves overall reliability. The coupling allows some flexibility for the repaired section. This helps with thermal expansion and minor pipe movement.
We have a full production line from casting to final packaging. We can custom-make products based on your requirements. Our quality team tests every product for strength and seal performance. We provide test reports with each shipment. We accept third-party inspections.

Solved a Community Water Leak
A residential community had a DN150 cast iron pipe section that was badly corroded. The bad section was about half a meter long. The maintenance team measured the section and ordered our Double Socket Repair Coupling. The socket spacing matched the removed section length exactly. They cut out the bad pipe and installed the coupling. The whole job took much less time than traditional methods. No extra pipe measurement or positioning was needed.
We offer a 10-year warranty. The housing is QT450 ductile iron with uniform wall thickness. The epoxy coating resists corrosion for buried service. Tell us the removed section length and pipe diameter. We will custom make the coupling for you.
