    摘要: The invention relates to the design of a multilayer reinforced polymeric pipe for water, namely, hot water in central heating and water supply systems, and may be used in pipes for transportation of liquid and gaseous media to which the pipe material is resistant in operation conditions. The 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 base polymeric layer of the proposed pipe is made of cross-linked or heat-resistant polymer, preferably polyethylene or polybutene. The reinforcing layer may be made in the form of a mesh. The reinforcing layer is 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. Thickness of the protective layer is at least 3 mm. A system of pipes for transportation of water, preferably hot water in central heating and water supply networks, 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.
