Repair Clamp for Cast Iron Pipe

The Cast Iron Pipe Repair Clamp (Banding Type) is made for small cast iron branch lines and service connections. Many city networks have small-diameter cast iron pipes feeding homes and businesses. These pipes rust through more easily because they have thinner walls. Our clamp gives you a quick, low-cost way to fix them.
 

For Small-Diameter Cast Iron Branch Lines

 

 

The Cast Iron Pipe Repair Clamp (Banding Type) is made for small cast iron branch lines and service connections. Many city networks have small-diameter cast iron pipes feeding homes and businesses. These pipes rust through more easily because they have thinner walls. Our clamp gives you a quick, low-cost way to fix them.

 

The clamp is a split-ring design. It is precision-cast from QT450 ductile iron. Inside, there is an EPDM sealing pad that is molded into the housing. Slide the clamp onto the pipe from the side. Align the ends and tighten the bolt. The sealing pad presses against the cast iron surface. Cast iron pipe surfaces are rough. Our sealing pad is thicker to fill surface irregularities. The housing wall is thin but strong enough for small pipes.

 

We are located in Nan'an City, Fujian Province. We benefit from the local casting and machining supply chain. We have our own R&D team and several patents. Our annual sales exceed 80 million RMB. Our quality team performs incoming inspection, in-process inspection, and final inspection on every batch.

Used in Old Community Networks

 

 

An old residential community in a northeastern city had many DN50 and DN80 cast iron branch pipes with pinhole leaks. Replacing these pipes would have required indoor work and caused disruption. The maintenance team used our Cast Iron Pipe Repair Clamp (Banding Type) for in-situ repairs. They fixed over 80 leaks. Each repair took about 20 minutes. This avoided major renovation work and resident complaints.

 

We offer a 10-year warranty. Each clamp is hydro-tested at 2.4 MPa before shipping. The epoxy coating resists corrosion in buried and wet conditions. Sizes match standard cast iron pipe ODs exactly.
