Steel pipe VGP DN 40x4.0 mm

Steel pipe VGP DN 40x4.0 mm is used for laying water and gas pipelines.

The standards and requirements that VGP pipes must comply with in terms of technical characteristics are detailed in GOST 3262-75.

A feature that distinguishes the VGP pipe is the presence of a reinforced electric weld. This allows higher internal pipe pressure to be tolerated. Also, the pipe according to GOST 3262 is highly resistant to corrosion.

     Substances transported through VGP pipes have different chemical composition, which affects the service life of a pipeline made of steel water and gas pipes. Due to the operation of VGP steel pipes in aggressive conditions (sunlight, precipitation, temperature and pressure drops, explosive substances), the welds of the water and gas pipe are checked for tightness and wear resistance using the X-ray method.

Pipes according to the accuracy class are divided into pipes of ordinary and increased accuracy. The chemical composition and mechanical characteristics of pipes of ordinary accuracy are not standardized, but at the same time they are successfully used for wiring communications to buildings and household buildings. But industrial pipelines are laid from high-precision pipes: with a check of the chemical composition and mechanical characteristics of steel tubular products. Galvanized pipes VGP also belong to pipes of increased accuracy. Welded seams of pipes of increased accuracy must be of a reinforced type to ensure the strength and reliability of industrial pipelines.

Conditional passage (hereinafter referred to as UE). The capacity of the VGP pipe depends on it. Usually, the UE parameters do not coincide with the size of the internal section of the steel pipe, since the former directly depends on the wall width. Parameters and values ​​of UE are regulated and controlled by GOST 28338-89.

     Welded water and gas pipes, due to their qualities, are used:

Ø for laying water supply systems, both industrial and domestic mains;

Ø for heating supply;

Ø for the construction of gas pipelines for various purposes;

Ø for the manufacture of various metal structures: scaffolding, fences and other types of fences, and so on;

Ø for the manufacture of small architectural forms: stairs, urns, benches and so on;

Ø for the manufacture of furniture frames;

Ø for the construction of frames of small buildings: verandas, greenhouses and so on.
