This type of steel products include cold-rolled and cold-deformed pipes of General purpose carbon and alloy steel (10, 20, 35, 40, 09G2S, 40X, 30KHGSA etc.) made on the outside diameter, wall thickness and length.

Depending on the quality indicators are divided into the following groups:

• B - with standard chemical composition of steel grades according to GOST 1050, GOST 14959, GOST 4543, GOST 19281;
• V - with standard mechanical properties that are controlled thermally treated samples and the chemical composition of steel grades according to GOST 1050, GOST 14959, GOST 4543, GOST 19281. Norms of mechanical properties shall conform to the requirements of the relevant standards for steel;
• D - without standardization of mechanical properties and chemical composition, but with the standard hydraulic test pressure;
• E - after special heat treatment. Steel grade, heat treatment regime and norms of mechanical properties are set by the documentation, duly approved.

The samples are thermally processed.
Without thermal treatment of produced pipe in which the ratio of outer diameter to wall thickness is 50 or more.

As these products work well on the bend, they are widely used for making furniture and lighting accessories.
