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.

Frequently Asked Questions (FAQ)
What pipe materials are compatible with the CHA-type flexible coupling?
The coupling is highly compatible with cast iron pipes, PVC-U, and HDPE drainage pipes, provided they have matching outer diameters. It serves as a universal connector across different pipe materials.
Does installing this coupling require welding or special adhesives?
No, it does not require welding, glue, flanges, or any hot-work operations. The installation is performed by directly sleeving the coupling onto the joint or crack and tightening the dual hexagon locking bolts.
How does the coupling handle pipe thermal expansion and ground settlement?
It features a multi-layer corrugated NBR rubber liner that provides an elastic buffer. This design compensates for pipe displacement, isolates vibration, and absorbs thermal expansion or foundation settlement to prevent pipeline cracking.
Can I order customized sizes or add our company logo?
Yes, we offer custom services including customized diameters, wider cylinder heights, and custom logo printing to meet specific project specifications.
What is the typical lead time and shipping method for orders?
The standard lead time for bulk orders is 5-10 working days. We support international shipping via sea, air, and express delivery, and offer small sample orders for quality testing.
