: Retailers like Tianjin Boer King Steel and Haihao Group stock seamless tubes meeting these specifications.
: 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.
This standard covers cold-drawn or cold-rolled seamless tubes designed for high-pressure resistance and structural integrity. gost 8737 75
: Seamless pipes can be identified by inspecting the cross-section; they must show a complete circle with no joint traces or weld seams on the inner or outer walls. Procurement and Availability
: Typically covers tubes with an outer diameter (OD) from 1 mm to 200 mm and wall thicknesses from 0.2 mm to 22 mm . : Retailers like Tianjin Boer King Steel and
: Common steel grades include Grade 20 (Steel 20), which offers a yield strength of approximately 245 MPa and a tensile strength of 412 MPa.
: Precision is verified using tools such as outside micrometers to ensure adherence to strict tolerance limits. : Seamless pipes can be identified by inspecting
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 While it has largely been superseded by or used in conjunction with GOST 8734-75 (which defines dimensions) and GOST 8733-74 (which defines technical requirements), it remains a critical reference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.
