Element T-03 is a composite material for factory application of polyethylene coating of pipes with improved physical and mechanical properties, increased resistance to cracking, impact and ultraviolet radiation, produced according to TU 20.16.10–002-88028259-2024
Element T-03 is designed to apply an anti-corrosion coating to large-diameter steel pipes by extrusion. Element T-03 is characterized by resistance to thermal-oxidative aging during processing and operation, as well as to photo-oxidative aging during operation. It is used for large-diameter pipes and operating temperatures up to +80 degrees Celsius.
