Pipes of heating systems are intended in order to supply and remove the required amount of coolant from the diverted devices. For heating systems, various types of pipes are used. Basically, heating pipes are made of materials such as copper, steel or polymers.
All materials for heat -insulating pipes have its advantages and disadvantages. In many Russian apartments, steel pipes are installed, which are subject to corrosion, however, such pipes have inexpensive cost. Many industrial areas cannot do without steel pipes. And in order to effectively reduce thermal losses in heating pipes, heat -insulating materials are used.
Steel pipes in thermal insulation are often used as pipes for heating the outer laying of pipelines. For such purposes, steel pipes that have an average size are usually used. The design of the heating pipe in the insulation PPU is created using a technology called “pipe into a pipe”, while such a pipe can be used up to 25 years, taking into account the temperature of the coolant to 140 ° C.
Heating pipes in the insulation PPU are made from a steel pipe, the heat -insulating layer of polyurethane foam, as well as from a protective polyethylene shell or galvanized steel. In order to isolate welded joints, heat -assembly couplings are used. Heating pipes in the insulation PPU are made using a special control system for moisturizing the heat -insulating layer, which can determine the damaged places of the protective membrane. It should be noted that heating pipes in the PPU isolation have the form of a single structure.
