The bellows-sealed compensator of axial (KSO) – appointment. SKU 1 in PPU-PE with UEC are intended for installation in pipelines at beskanalny laying on straight sections of pipelines in isolation PPU between the BUT motionless support in item PPU e. with UEC. Change of temperature condition of a thermal network leads to temperature expansion or compression of material of pipes and to increase or reduction of length of the pipeline clamped between motionless support. It leads to growth of tension in material of pipes which sizes can reach destructive values. In order to avoid emergence of such tension also establish SKU. Corrugations of bellow valves, it is elastic being deformed, perceive changes of length of sites of the pipeline within the axial course. SKU are delivered in uncompressed, zero situation at which their course on compression is equal to the course on stretching, the size of the course depends on diameter of the pipeline and manufacturing firm of the bellow valve.
For elevated laying of pipelines in isolation PPU the bellows-sealed compensator is isolated similar to pipes and other shaped elements of this type of laying - a steel galvanized cover (OTs) for protection of the bellow valve, a steel casing and rigid heat-insulating polyurethane foam (PPU) against mechanical damages, solar radiation and an atmospheric precipitation. The enterprise of a pipe in SPb can apply to PPU isolation on bellows-sealed compensators (KSO, SKU) with the UEC system conductors laid in product thermal insulation. One acts as the main unit of this compensation product - or two section bellow valve which is made from stainless steel or the titan. http://sis-truba.ru/, ph.
