Quick-detachable constructions Elbows PIPEWOOL

TECHNICAL CONDITIONS 23.99.19-004-61278130-2017

Quick-detachable design (QDC) on the branch – a ready-made and modern solution for the protection of pipeline networks from external influences. QDC is a prefabricated structure made of a heat-insulating layer with a protective coating of sheet steel. Special stiffeners, longitudinal and end overlays, technological locks prevent moisture from entering the casing, and bandages with buckles or locks reliably ensure the integrity of the structure from external influences.

Truncated or beveled branch-is used in hard-to-reach or cramped conditions of dehumidification, as a rule, these are the places where the branches intersect with the pipeline and any building structures and equipment. Any segment or several segments on any side can be truncated, as well as with alternating segments and sides.

Tap of the transition section-used in places of rotation, where the technological transition of the pipe from one section to another is necessary.

Double vertical and horizontal tap-used in tight conditions, in which the pipes in the places of rotation are located too close to each other and okozhushivanie must be made entirely on two pipes.

Quick-detachable structures QDC is characterized by efficient performance, withstands high operating temperatures, effectively retains heat, is strong and durable. Easy to cut and other processing, easy to install.

   Mineral wool thermal insulation of QDC is not affected by chemical elements (alkalis, acids), as well as ultra-violet and electro-magnetic radiation, is easy to install and very technologically advanced in processing (easily cut even with household tools), is durable and retains its working properties throughout the entire service life.

   The anti-vandal shell of the QDC made of thin-sheet steel is resistant to mechanical loads, anti-corrosion, low thermal conductivity, moisture resistance, non-combustibility.
   Due to the fact that the galvanized casing of the QDC consists of several segments and has snap-on grooves, it is easy to install in the shortest possible time. In addition, this collapsible design provides free access to the pipeline and allows for quick repair work. Installation does not require special skills, since basalt insulation is easily cut into the desired segments. Galvanized steel has remarkable performance characteristics – it is resistant to mechanical loads, is not subject to corrosion, allows you to quickly get free access to the pipe, carry out work related to the operation of the pipeline.
