OREANDA-NEWS. TMK, one of the world’s leading producers of tubular products for the oil and gas industry, has shipped a batch of vacuum insulated tubing (VIT) to Gazprom Dobycha Yamburg, which develops the Yamburgskoye and Zapolyarnoye oil and gas condensate fields in the Yamal-Nenets Autonomous Area.

The shipment included 2,849 linear meters of low-temperature N80-grade 89 mm VIT with 6.45 mm walls and 60 mm VIT with 4.83 mm walls complete with ТМК UP™ FMT premium threaded connections. The tubes were produced at TMK’s Sinarsky Pipe Plant. This type and size of VIT has never been supplied to Gazprom Dobycha Yamburg before.

TMK was the first Russian company to launch VIT production in 2011. VIT is a complex assembly: a smaller diameter tube is enclosed within a larger diameter tube. The space in between them is filled with multilayer insulation to reduce heat loss and the air is evacuated. The tubing is designed for use at oil and gas fields in the permafrost zone as the upper section of a tubing string; it prevents thawing of frozen soil around the well.

ТМК UP™ FMT tubing connections ensure high tightness in adverse conditions (extreme bending, compressive and tensile loads, torque, aggressive environments). In 2015, TMK’s share in the premium threaded connections segment of the Russian market reached 73%.
