Mastics

Mastics are designed for pipe coating when re-insulating pipes during gas pipeline routing. The mastics are for pipes of a diameter up to 1420 mm, inclusive; operating temperature: up to 35 . Mastics have high operational, physical and mechanical performance properties.

The quality and conformity of all the materials have been qualified with top oil-and- gas R&D institutions, such as Scientific-Research Institute of Natural Gases and Gas Technologies GAZPROM VNIIGAZ, Scientific and Research Institute for Oil and Oil Products Transportation (NII TNN) , Russian National Scientific Research Institute for the Construction and Operation of Fuel and Power Sector Pipelines and Facilities (VNIIST). The materials are on the Insulation Materials List of OJSC Gazprom.
