The PVC enclosed type flange is a card type connection, makes the pipeline construction to be simpler and faster, and save the installation space greatly. Because the compound board and the PVC flange use, the entire pipeline processes the mechanization, causes the length of pipe and the flange surface verticality, the parallelism can guarantee, the same size pipeline has the good interchangeability, after causes the installment the overall pipe network internal stress to become very much small, thus enhanced the overall pipeline gas tightness, improved the pipeline overall quality greatly.

Our PVC flanges are made of non-recycled material may reach the B1 fire-resistance. PVC flanges are widely used in HVAC industry for the conjunction of Phenolic aluminum Foil Compound Air duct system, XPS-aluminum foil compound air duct system and fiber glass aluminum foil compound air duct system etc. The product has an artistic appearance, easy to application, environment friendly, flame-resistant and with competitive price. Our PVC flanges achieve the air duct system extremely low leakage and prolong the service life.
