Wearing material is intended for protection of isolation coating for pepelines with diameter ranging from 478 to 1420 mm. Inclusively from mechanical damage during installation and exploitation cast-iron and reinforced concrete densifiers of annular type. And also for anchor stretchers and also for quick fixes of pipe whip. The material constructed in climatic modification UHL as per GOST15150. WM is designed for exploitation at macro-climatic area with a moderate cold climate at temperatures from 60 below zero to 40 above zero. Life cycle as long as pipeline.
