Seamless cold-deformed steel pipe is designed for pipelines, structures, parts of machines, automotive, aircraft engineering, shipbuilding, chemical, and mechanical engineering industries, cryogenic engineering, fuel and energy plants and other technical purposes. They are also widely used in the shipbuilding industry.
Electric-welded longitudinal cold-deformed pipe exposed to cold deformation after welding.
The range of cold-deformed pipes complies with GOST 8734-78.
Depending on the ratio of pipe diameter (D) to wall thickness (s), cold-deformed pipes are divided into:
Thick-walled cold-deformed steel pipes are manufactured with heat treatment. Thin-walled cold-deformed steel pipes are manufactured without heat treatment. D/s ratio of these cold-rolled pipes is equal to 50 and more.
Thin-walled cold-deformed pipes as per GOST 8734-78 are widely used in the furniture industry.
According to the length, cold-deformed pipes as per GOST 8734-78 are divided into:
According to quality standards, thick- and thin-walled cold-deformed pipes as per GOST 8734-78 are divided into B, C, E, F groups:
WE WILL DELIVER NEW COLD-DEFORMED PIPES AS PER GOST 8734-78 AT PRICES WHICH ARE LOWER THAN MANUFACTURER PRICES.
