GOST 10704-91

JSC "Uraltekhmarket" offers Pipe rolling, appropriately GOST 10704-91.

According to GOST 28548-90 "welded pipe" is a product made of strips or sheet metal by molding and subsequent welding.

Alloy additives in the steel, increase the strength characteristics of pipes.


Electrically welded tube is one of the most common materials used in construction of buildings, structures, pipelines, advertising structures, as well as in the regeneration of playgrounds, metal furniture, etc. of Course, in each case, the welded tubes of different types, sizes and made of various steel grades.

Assortment complies with GOST 10704-91 (239 kb) .

Electrically welded tube is one of the most common materials used in construction of buildings, structures, pipelines, advertising structures, as well as in the regeneration of playgrounds, metal furniture, etc. of Course, in each case, the welded tubes of different types, sizes and made of various steel grades.

The range of longitudinal electric-welded pipes GOST 10704-91 determines. This standard specifies the requirements for pipes made from the point of view of their dimensions and permissible variations.

The outer diameter: 12, 14, 16, 18, 19, 20, 21,3, 22, 24, 25, 26, 28, 30, 32, 33, 33,7, 36, 38, 40, 42, 45, 48, 51, 54, 57, 60, 63,5, 76, 89, 102, 108, 114, 133, 140, 152, 159, 180, 219, 273.

Wall thickness: 1, 1.2, 1.4, 1.5, 1.6, 1.8, 2, 2.2, 2.5, 2.8, 3, 3.2, 3.5, 3.8, 4, 4.5, 5,5; 6, 7 ,8 ,9.

Limit deviation:


diameter
D 12 - 30 mm: ± 0,3 mm
D 32 - 51 mm: ± 0.4 mm
D 57 - 108 mm: ± 0,8 mm

Welded steel pipes are usually made of low alloy or carbon steel using welding. The use of such steel provides the products not only strength and durability but also flexibility. The workpiece for welded pipe is a molded strip. The seam in the pipe can be spiral or longitudinal. Welded joint has been heat treated. Weld quality is monitored with the help of non-destructive testing ultrasonic inspection.

This technology allows to obtain tubes with different shape of section: round, rectangular, square, etc.

Electric-welded longitudinal steel pipes have a single longitudinal seam parallel to the axis of the pipe itself.

Technical requirements for pipe in this category reglamentary GOST 10705-80.

Thin-walled pipes GOST 10704 91 with the surface of high quality is produced from cold rolled steel. It allows to improve their mechanical properties and to obtain a smooth surface. Thin-walled welded pipe 10704 is light in weight and used for mounting light structures: fences and fences, frames, partitions, furniture, air-conditioning and ventilation systems, etc.

In the construction and erection of structures often used shaped tubes with rectangular or square cross-section. Their strength and efficiency allow them to replace the slabs, beams, channel, etc.

Thick-walled pipe GOST 10704 used in trunk heat networks, such pipes transporterowych oil, gas, petroleum products, etc.
