Product Description

GOST 8732-78 10th 09G2S 15X Hot Deformed Seamless Pipe  

Hot-rolled steel seamless pipes are the most common format successfully used in all national economic sectors. These products are known for the greatest reliability, especially for laying communications for various purposes. Most often, a seamless hot-deformed steel pipe GOST 8732-78 is used in the construction of monolithic-frame structures, where reliability is above all under such impressive loads.

Standardization hot rolling seamless tubes 8732 are produced from steel billets of the main grades:

• 10th, 20th, 35th and 45th standard;
• 35V;
• 40G and 45G;
• 15X and 40X;
• 9X1;
• 20PV;
• 30KhGSA;
• 17G1S,
• 09G2S;
• 10-20DDD.
