Pipe is produced of galvanized and non-galvanized strip of own production. The price for batches from 20 tones is agreed individually. Steel grades used for square shaped pipe production are regulated with GOST According to technical requirements of normative documents pipe is produced:.

The company has developed and implemented an integrated management system IMS , confirmed by the compliance certificate. Weld seam test of shaped steel pipes is carried out at electric magnaflux plant UMDM. Plant operation principle is based on creating of static magnetic field in tested objet and transformation of the field changes leakage into electric signal — defect signal.

Defect detector works in continuously-automated operating mode and while pipe moves it carries out non-destructive control testing of weld discontinuity, it also registers defects and informs the operator about the quality of weld seam, its deseaming and geometry.

Immediate receiving of information shows the welder correctness or incorrectness of pipe forming operation and welding of shaped pipes. Not presented dimensions of square shaped pipe can be agreed individually.

Dimension tolerances are regulated by par. Mechanical properties of square shaped pipe are regulated with GOST Depending on the application pipe is produced of the following groups:. Packing interval — 0,5 m from package end and further on at the distance of at least 1,5 m. Packing is carried out by import equipment Signode, providing ideal tension and package safety. Product transportation is possible without using bolsters. While transporting recently produced pipes, one shall take into account that all shaped pipes are thoroughly oiled.

Shaped steel pipe is one of the steel product types used as a construction material. The assortment of produced pipes includes profiles of different shapes, but the most popular are square pipe and rectangular pipe.

Plasticity properties of the steel used in pipe production, allows to produce folded shaped pipes. Special mills and equipment — pipe benders — are used for bending. Galvanized shaped steel pipe is a product manufactured of cold-rolled galvanized steel. Main application of shaped pipes is steel products manufacturing. Shaped pipes are used for building of different constructions: farms, gates, greenhouses, sheds etc. Besides they can be also used for making such objects as: bench, stairs, summerhouse, wicket, fence and so on.

Main application of shaped pipes is connected with sustainable resistance to lateral loads. Planes situating perpendicularly to the pressure direction can provide higher resistance to pressure. This property makes profiled pipes more convenient in comparison with flexible round pipes. In case if the pressure direction is already known the strength characteristics of the pipe can be strengthened in advance by using rectangular section instead of square one.

Generally it turns out that when using these pipe types in building structures specific consumption of steel materials can be reduced as well as costs. Another advantage is more stable attachment of various building materials to a smooth plane.

Types and steel grades. Dimentions and properties. Types Square shaped pipe produced by the company in zinkcoated and noncoated types. Integrated Management System The company has developed and implemented an integrated management system IMS , confirmed by the compliance certificate.

Weld seam test Weld seam test of shaped steel pipes is carried out at electric magnaflux plant UMDM. Package length: 6; 11,7 and 12m other dimensions can be agreed individually. Description Shaped steel pipe is one of the steel product types used as a construction material.

Application field Main application of shaped pipes is steel products manufacturing. Advantages Main application of shaped pipes is connected with sustainable resistance to lateral loads. Closed profile.
