Sandwich tube - modern chimney design

Until now, some citizens use brickwork as a chimney structure, which requires frequent repairs and regular cleaning (about 1-2 times a year). But not everyone knows that there are designs that can be installed in one day without additional workflow and special tools.

Innovation in the construction industry is a sandwich tube, which is used as a standard rectilinear two-circuit modular (1 or 0.5 m) element of chimney systems with different chimney diameters. The main purpose of this pipe is the fire-safe removal of flue gases from heat-generating apparatus to the atmosphere.

The sandwich tube consists of two stainless pipes of different diameters, as well as a thermal insulation made of cotton wool from basalt.

An effective heat-insulating layer in this pipe provides the solution of such important problems as excessive heating of the outer wall and the formation of condensate, which is accompanied by deposits of soot on the chimney walls. A pipe sandwich has a simple installation, as a result of which every person can implement it. The specified production is carried out in parts with a length of no more than 1 m. In the assembly set of the chimney sandwich there are corners, adapters, cones of the required diameters, tees with thread, fungi, revisions and so on.

A small complication in the installation process can occur in the connecting places, but the manufacturers have provided a solution to this problem by making details that facilitate the work. The sandwich tube has panels that are very aesthetic and easy to care for: they do not need to be cleaned, dyed, etc. This system is thought through to the smallest detail, and in addition, it has a long service life, which, if properly installed, can be a minimum of 15 years. The chimney sandwich during installation requires a lot of necessary elements provided by the manufacturer, such as a weather vane, spark arrestor, deflector, unloading platform, clamps for fastenings. In addition, the presence of a solution, heat-resistant sealant, metal rats, that is, ready pipe joints through the roof, can be useful. Virtually any pipe sandwich can be mounted from an existing set of finished parts. The compactness, quality and light weight of these materials makes it easy to install a chimney system and turns this process into pleasure only if the correct assembly of the structure is carried out, which includes several rules:

- Installation of sandwich pipes should include two principles:

• "By condensate" - if the system does not require the presence of a tee;

• "By smoke" - if a tee is used to ensure the withdrawal of the condensate liquid.

- In addition to the existing sufficient thermal protection of these pipes, it is recommended to install additional protection when they are withdrawn in fire-hazardous areas: a wooden wall, a beam, a ceiling, a roof.

- It is strictly forbidden to install a sandwich pipe directly above the combustion unit.
