Quick-detachable constructions Tees PIPEWOOL

TECHNICAL CONDITIONS 23.99.19-004-61278130-2017

   The quick-detachable design (QDC) on the tee is a ready-made and modern solution for protecting 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.

   The quick-detachable design on the tee serves as a protection on the branch of the pipeline (tee) with a diameter of 60 to 1000 mm. They are made of galvanized steel, stainless steel and aluminum sheets with a thickness of up to 0.50 – 1.0 mm. Special stiffeners, longitudinal and end overlays, technological locks prevent moisture from entering the casing. It is performed as standard at 90°, 45° (other options are possible).

Types of execution of a tee – equal-pass, unequal-pass, with an axis offset.


3. Equal-pass at an angle
4.Transition at an angle
5.No offset
6.With offset

   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.
