Pipe producers ask "Gazprom" to reconsider the purchase prices for the pipes.
Last year's collapse of the rouble forced pipe producers ask "Gazprom" to revise the prices of their products.
Since May 2012 "Gazprom" pays for the pipes according to the formula price. But due to a sharp change in the market the system had failed, four employees of different pipe manufacturers told "the Vedomosti". Producers had to begin negotiations with "Gazprom" to raise prices on the pipes, they state. At the same time the shipment of products does not stop.
