PVC expansion joint, also known as PVC expansion joint, is used for PVC pipe system accessories, can deal with the pipe due to temperature changes caused by expansion, made of adaptable materials, with good sealing and expansion, to ensure stable pipeline connection. Directly from the manufacturer, support wholesale, consult contact 13339996652. Specifications and models are diverse, common calibers are 50mm, 75mm, 110mm, etc., adapt to the corresponding specifications of PVC pipe, expansion and contraction according to the use of the scene design, interface size and pipe matching, easy installation, no complex tools can complete the assembly. Wide range of use scenarios, suitable for building drainage risers, long-distance PVC pipe laying, pipe connections in large temperature environments, etc., play a role in compensating the amount of expansion and contraction in the pipeline system, avoid pipeline deformation due to thermal expansion and contraction or interface leakage, ensure stable pipeline operation and reduce maintenance costs.
