GOST 9941-81 is a standard that specifies the requirements for seamless steel tubes in Russia. This standard is used to ensure that the tubes meet specific criteria regarding their dimensions, tolerances, and technical requirements.

Seamless tubes, as described by GOST 9941-81, are typically used in high-pressure applications, such as in the oil and gas industry, power plants, and various industrial machinery where strength and durability are critical.
