Heavy Duty Stainless Steel CHA Type Pipe Coupling Flexible Connector for Cast Iron PVC Drainage Pipe Repair Clamp

Product Overview

This heavy-duty CHA-type flexible pipe coupling is a professional pipeline connecting and repairing fitting, widely used in residential, commercial and municipal drainage engineering. The whole sleeve is rolled from thick stainless steel, equipped with corrugated NBR rubber inner gasket and double high-strength hex locking bolts. It realizes flexible sealing connection without welding, glue or flange, effectively absorbing pipe thermal expansion, vibration and foundation settlement to avoid pipeline cracking and water leakage.

 Key Features

1. Stainless Steel Heavy Body
   201/304 stainless steel thickened cylinder, anti-rust, acid & alkali resistance, suitable for underground wet pipeline environment.
2. Multi-Layer Corrugated NBR Rubber Liner
   Elastic buffer design, compensate pipe displacement, isolate vibration, excellent sealing performance against sewage and wastewater.
3. Double Hexagon Bolt Locking System
   Uniform pressure distribution, tight fit without gap, easy manual tightening, stable long-term sealing effect.
4. Wide Compatibility
   Fit cast iron pipe, PVC-U, HDPE drainage pipe with matching outer diameter, one coupling for multiple pipe types.
5. Fast Installation & Emergency Repair
   No fire operation, no adhesive, direct sleeve on pipe joint or crack for quick leak fixing, greatly save construction time and labor cost.
