LABORATORY SIMULATION OF FAILURE MECHANISMS IN PIPES MADE OF FLEXIBLE AND RIGID POLYMER-REINFORCED MATERIALS AND USED IN THE OIL AND GAS INDUSTRY

To meet the growing needs of operating organizations for reliable and uninterrupted transportation of hydrocarbon raw materials, composite pipes made of polymer materials are increasingly used. Polymer-reinforced pipes, rigid and flexible, are also used in many industries to transport bottom water, oil, and gas since they are resistant to corrosion and lighter than metal pipes. Polymer pipes with various reinforcement systems have mechanical properties that provide flexibility, strength, durability, and economic benefit in operation compared to pipes made of other materials. This paper considers using laboratory equipment to simulate the conditions of failure of rigid and flexible polymer-reinforced pipes under maximum internal pressure in order to assess their performance and predict their service life under specified operating conditions.
