Among tubular metal, implemented by JSC "PTC-Ekaterinburg" a wide assortment of profile pipes, this group includes pipes made of carbon and low alloy steel.
Profile pipe – a pipe with a cross section different from circular. Are made oval as well as square and rectangular pipes.
Main material — carbon and low-alloy steel (typically st3sp or 09G2C)
All products meet applicable standards: GOST 8645-68 and GOST 8639-82, GOST 30245-2003.
Profile pipe is made by cold or hot deformation. Each of these technologies defines the qualities and characteristics of a pipe to enable its use in a particular area.
That is the first piece — the "strip" to bend and weld the round tube design of the cross section, then round pipe enters the forming rolls special where she is given the desired cross-section. After that, all the pipes, according to GOST, are non-destructive testing of the weld optionally thermally processed to remove the internal mechanical stress. This leads to their strength, lightness, efficiency, damage resistance, ease of use. Cross-section produced in Russia shaped tubes are 10×10 mm up to 500x400 mm. wall Thickness range from 1 mm to 22 mm. pipe Length from 6.0 to 18.0 m
In the form section there are the following types of pipes:
Sizes and parameters, the method of production and grade of steel are determined by the requirements of strength, lightness, project and purpose.
