Plumber jargon, WGP - Water and Gas Pipe Second type of arc-welded tubes, GOST 3262-75. Unlike the tubes in accordance with GOST 10704/10705, these tubes are classified not by the actual OD, but by DN rated dia. That is why they are specified by their DN (rated diameter). One more difference: WGP tubes are manufactured in three wall thickness versions only: light, normal and heavy.
