The gas pipeline "Power of Siberia" is exploitated with anticorrosion coating of METACLAY JSC.

Yesterday, 02.12.2019, the 1st stage of the Power of Siberia gas trunkline was launched by means of a teleconference bridge with Russian President Vladimir Putin and Chinese President Xi Jinping. The 2200 km long section connected the Chayanda field in Yakutia with China on the border with Blagoveshchensk. The design capacity of the gas pipeline is 38 billion cubic meters per year.

This is a significant date for the staff of METACLAY JSC, as the steel pipes of the Power of Siberia are insulated with polyethylene anticorrosive coating of its production. Firstly, a three-layer coating system made of METALEN PE-1 (polyethylene) and METALEN APE-1 (adhesive) components was used for the gas main pipeline, and then - a monolayer based on METALEN PE-21 material, which innovatively combines polyethylene and adhesive and due to this saves time and means of installation for PJSC "Gazprom". Monolayer coating as an alternative to three-layer coating was launched into production by METACLAY JSC for the first time in the world. The effectiveness of this coating has been confirmed by Gazprom's STO system as well as by tests at pipe plants. METACLAY" monolayer coating provides shock resistance, reliable protection against moisture and resistance to temperature changes from +80 to -80 degrees Celsius. The advantages of the monolayer coating have made it the main polymeric anticorrosive material for isolation of the gas main pipeline.

The suppliers of steel pipes with materials METALEN PE-21, METALEN PE-1, METALEN APE-1 for the construction of the Power of Siberia gas pipeline were partners of METACLAY JSC: Chelyabinsk Tube Rolling Plant JSC, Izhora Pipe Plant JSC (Severstal), Vyksa Metallurgical Plant JSC (OMK).

Along with polymeric anticorrosive coating, another METACLAY product was also used for the gas pipeline. - LITOMET electro-isolating spoons to reduce the effect of stray currents, prevent galvanic and crevice corrosion from both mechanical and damage.

METACLAY is proud of its participation in the strategic federal project to build the Power of Siberia. This tremendous experience and responsibility has allowed us to acquire expertise and resources to develop and commercialize materials and technologies for the pipe industry.
