PEX Pipe Plumbing

The main task of technical insulation

In this article, the head of design and technical direction of the company
“Evro thermo” Dmitr Smilets talks about what functions and tasks
can perform the technical insulation.

Among the main objectives are the following:
# Effective reduction in heat loss. Application of high-quality insulation, with proven heat engineering parameters can significantly reduce heat loss in heating and hot water.
# Prevent condensation or freezing. This problem is most acute in the cooling system and cold water. A correctly designed, with reasonably calculated thickness, insulation eliminates condensation on the surface of the system, ensures the absence of frostbite on systems with operating temperatures below 0 ° C.
# Ensure the desired temperature at the surface of the insulation. In the working areas of the premises and served to the surface of insulation to maintain temperature for a safe location of people and creating favorable conditions for human life.
# Reducing noise from the utilities. The use of insulation can significantly reduce the noise from ventilation systems, water supply and sanitation, which is important for both residential and commercial construction.

If you talk about the other functions of technical insulation, then they are:
# Extension of the operation of engineering systems;
# Extra protection against corrosion;
# Prevent freezing of water in the PEX pipe system.
Please keep in mind that whatever the specific task is not executed technical insulation, it will always reduce loss of heat or cold, reducing energy costs.
Also, when choosing technical insulation should be aware that only properly selected material type, designed by experts wall thickness and quality installation will ensure the implementation of isolation of all functions.

PEX Pipe Plumbing

PEX Pipe Plumbing consists of several, or rather of the five (!) Layers: the internal (PEX) and external (PE) layers, the aluminum layer between them and connecting the layers of glue. Despite its multi-layer, pipe Plumbing are flexible, while retaining its shape. Coefficient of linear thermal expansion of pipe Plumbing is comparable to the coefficient of expansion of copper pipe.

To produce PEX  fitting Plumbing applied polymer new generation – Polyphenylsulphone (PPSU). This material has high impact and heat resistance, experts compare it with metal. But unlike metal Polyphenylsulphone absolutely not subject to corrosion.

The cost of metal pipes FUTURE K -1, depending on the diameter range from 1,9 to 8,4 Euro per meter.

Based on the data in the table, we can say that at 90 ° C and metal-tube pipe cross-linked PEX are more resistant to high pressures.
