Multi-layer plastic tube for water conveyance

摘要

The multilayer tube (T) made of plastic material for chlorinated water conveyance under pressure, comprises an external layer (C1) having a sufficient thickness and an internal layer (C3) such as a barrier layer connected to the external layer by an intermediate layer (C2) of a binder. The thickness of the inner layer is less than 1 mm so that the tube is rollable for an average diameter of one meter. The thickness of the intermediate layer is less than 0.2 mm. The peeling force of the inner layer is greater than 20 N/cm. The tube is obtained by co-extrusion of the three layers.
