Tube of Thermoplastic material for conduction of water, with external protection to the action of weathering

摘要

A tube is suitable for being used in Fluid Network, urban facilities in general, at home, both domestic and industrial. Belongs to the type that combines the use of an internal layer with low roughness Index, with an intermediate layer of Greater thickness, termofusionable formed with a plastic material, such as polyethylene.This is because the intermediate Layer termofusionable, is covered by an outer cover of plastic material such as polyethylene Treatment barrier to the action of UV Light, black color, with a thickness of between 20% and 30% of the total thickness of the tube.In this case the Middle wall is a polyethylene Green color that has a thickness of between 30% and 60% of the total thickness of the tube, while the Inner wall is a polyethylene, polypropylene homopolymer or a Pure high molecular weight, and has a thickness of between 2% 6 % of the total thickness of the tube.
