MULTILAYER REINFORCED POLYMER PIPE AND PIPE SYSTEM FOR WATER TRANSPORTATION Russian patent published in 2012 - IPC F16L9/12 

FIELD: construction.

SUBSTANCE: multilayer reinforced polymer pipe comprising the main layer, at least one reinforcement layer, an adhesive layer and a protective layer, besides, the adhesive layer is made of a material without adhesion to the reinforcement layer material, and forms channels for reversible displacement of reinforcement layer threads. The pipe system for water transportation, preferably, hot water in networks of centralised heat supply and water supply, comprising two or more multilayer reinforced polymer pipes.

EFFECT: elimination of damage of polymer pipe layers, surrounding a reinforcement layer, due to provision of the possibility of axial displacement of reinforcement threads inside a pipe structure under impact of cyclic variations of temperature and mechanical loads.
