Interpipe has begun producing big-diameter seamless pipes according to GOST and EN standards. The pipes have been developed at Interpipe NTRP, where the previous maximum mill range was limited to 377mm.
In October 2012 the experimental pipes of 426 mm in diameter with 10 mm wall thickness were produced for Belorussian consumers. In January 2013 there has been one more break-through, a new dimension size of 406.4 mm in diameter with wall thickness of 50 and 68 mm made according to GOST standard for the 32XA steel grade. These were developed for Polish consumers. And finally in the 3rd quarter of 2013 Interpipe produced and delivered to German consumers pipes of 406.4 mm in diameter with 10 – 70 mm wall thickness in accordance with European standards EN 10210-1,2 and EN 10297-1 in steel grades S355J2H/E355.
Ivan Mazanka, Regional Sales Director for Europe at Interpipe, said: "The big diameter seamless pipes are currently in high demand globally; however, the number of suppliers for these products is limited. For this reason manufacturing of pipes 406.4 mm and 426 mm in diameter according to euro-standards is a very good opportunity for us to meet these needs by delivering high quality products in accordance with our European customers’ requirements.
