MULTILAYER REINFORCED POLYMERIC PIPE AND SYSTEM OF PIPES FOR WATER TRANSPORTATION

摘要

The invention relates to the design of a multilayer reinforced polymeric pipe for water, in particular, hot water in systems of centralized heat and hot water supply and can be used in pipes for transporting liquid and gaseous mediums to which the pipe material is stable in operation conditions. A multilayer reinforced polymeric pipe comprises a polymeric base layer, at least one barrier layer, at least one reinforcing layer, an adhesive layer and a protective layer. The adhesive layer is made from a material which does not adhere to the material of the reinforcing layer and forms channels for the free movement of the fibers of the reinforcing layer. The main polymeric base layer is made from cross-linked or a heat-resistant polymer, preferably polyethylene or polybutene. The reinforcing layer is made in the form of a mesh and made of high-strength and high-modular polymeric fibers, preferably aramid, polyester, or polyethylene fibers. The barrier layer is made of polar and nonpolar polymers. The protective layer is made of polyethylene of medium density. The thickness of the protective layer is at least 3 mm. A system of pipes for water, preferably hot water of centralized heat and hot water supply consisting of two or more multilayer reinforced polymeric pipes. The technical result consists in allowing the axial displacement of the reinforcing fibers inside the pipe structure under the effect of cyclic changes in temperature and mechanical load while maintaining the mesh structure and preventing damage to the polymeric layers of the pipe which surround the reinforcing layer.
