: Precision is verified using tools such as outside micrometers to ensure adherence to strict tolerance limits.
The is a legacy Soviet-era standard that specifies the dimensions and technical requirements for seamless cold-formed steel tubes . While it has largely been superseded by or used in conjunction with GOST 8734-75 (which defines dimensions) and GOST 8733-74 (which defines technical requirements), it remains a critical reference for specialized industrial components and inspection guidelines.

: Typically covers tubes with an outer diameter (OD) from 1 mm to 200 mm and wall thicknesses from 0.2 mm to 22 mm .
: Cold-forming (drawing or rolling) from a solid cylindrical bar, which ensures higher dimensional accuracy and a superior surface finish compared to hot-formed alternatives.
: Common steel grades include Grade 20 (Steel 20), which offers a yield strength of approximately 245 MPa and a tensile strength of 412 MPa.
