Russia's largest oil and gas pipe producer TMK has announced that it has begun shipments of longitudinal welded large diameter (LD) pipes to Russia's biggest gas company Gazprom for the construction of the 1,100 km Bovanenkovo-Ukhta gas pipeline, which is a part of the company's Yamal Megaproject.
Accordingly, during the month of March 2009, TMK is to deliver 5,000 mt of longitudinal welded pipes of K60 grade with 1,420 mm in diameter and 26.4 mm wall thickness, and with internal and external anticorrosion coatings.
The pipes are to be produced by TMK's subsidiary Volzhsky Pipe Plant (VTZ) at its newly commissioned LD longitudinal welded pipe mill, which is able to produce longitudinal welded pipes with diameters between 530 mm and 1,420 mm, wall thickness of up to 42 mm, and up to X100 strength groups, which correspond to Gazprom's and Transneft's standards for new pipelines such as Nord Stream, Eastern Siberia-Pacific and others.
