GOST 10704-91 Welded Steel Tube
Electric-welded straight-seam steel tube to Russian standard GOST 10704-91 in carbon and low-alloy grades. We supply small and medium outside diameters with Russian-language documents and mill test certificates on every lot, for delivery to Russia and the CIS or to your forwarding agent in China.
Price: quoted per specification and confirmed at the time of order, because steel prices follow the raw-material market.

Need precision instead of general-purpose tube?
GOST 10704-91 covers general-purpose welded pipe. When the part needs a close outside-diameter or wall tolerance, we weld the strip and then cold draw it to EN 10305-2 or DIN 2393; the certificate can carry both the GOST and the precision standard.
Quality and packing
Each lot is tested for chemical composition, mechanical properties, dimensions and surface, with flattening tests on request. Straight lengths are bundled and strapped; coil delivery is available for small OD. Ends are protected and the bundle marked per the purchase order.
Request a quotation: send the OD, wall, grade, length and destination through our contact page. We reply within one working day.
