Description
VUS pipes are the most modern technology of enhanced protection. It is based on the use of a dense layer of extruded polyethylene, which allows to achieve a more significant protective effect compared to traditional technologies. First of all, extruded polyethylene protects the pipe surface from corrosion, thereby extending its service life. It also protects the pipe from chemical and mechanical influences, significantly reduces heat loss, and provides high resistance to moisture.

The VUS coating is characterized by high adhesion to the pipe surface. Due to this, even when used in difficult conditions and under high loads, the integrity of the coating is preserved, it does not peel off the surface. VUS pipes can be used for up to 50-60 years, ensuring uninterrupted operation of the pipeline and without the need for repair.

Scope of application of VUS pipes

VUS pipes are widely used in the laying of main and field gas pipelines. They are used for the installation of oil pipelines. They can also be used for the construction of traditional water supply systems. Such pipes are equally suitable for both underground and above-ground installation. Another feature is the possibility of using them for underwater installation. They can be used in a wide temperature range: from -20 to +60 degrees Celsius. They are also not subject to the negative impact of temperature changes, which is extremely important when using such pipes in the Russian climate.

The flat-slot extrusion method is most often used to manufacture VUS pipes. It consists of the following. First, the pipe is heated, after which an adhesive layer with high adhesive properties is applied to its surface using an extruder. A polyethylene coating is applied over the adhesive layer, the thickness of which depends on the intended purpose of the pipe, the conditions in which it will be used, etc.
