Qualitative project – a basis for future engineering system of any home, regardless of whether it is constructed or reconstructed. On what materials and techniques are now being laid in the projects of construction and reconstruction of engineering networks, says chief specialist research part of PEX pipe vs Copper pipe.
- It would be wrong to think that PEX tubing – an innovation in our construction market. Plastic plumbing tubing our institute has designed before the adjustment. The first on the USA market then came Polish producers of PEX tubing, then Swedish, German, Finnish, finally there were domestic manufacturers. Now manufacturers became so numerous that the emergence of new materials it is difficult to track.
Therefore, to say exactly what materials and what country today is preferred, it is impossible. First, because we, as designers, do not focus on a specific brand, and based on technical characteristics of the tubing and its purpose. Secondly, it is necessary to take into account the opinion of the customer, which is now free to complete the project, based on their financial capabilities.
In designing in-house wiring of new residential buildings for hot and cold water, we use PEX tubing for heating – metal, for plumbing – polyethylene tubing low pressure, sometimes at the request of the customer – the cast iron. This also applies to those houses that are used for reconstruction. A fundamental principle in the selection of materials for engineering systems is primarily the ratio of price – quality.
The highest priority should be to the certificates: PEX tubing have different characteristics, including the ultimate pressure and working temperature. In most cases, this figure does not exceed 65-75 ° C. Therefore, for heating, which allowed the maximum coolant temperature to 115 ° C and can not be excluded, hydraulic shocks, the use of PEX tubing inappropriate.
