PRAWTECH sp. z oo. announces that a contract concerning the funding of a project ”Opracowanie Planu Rozwoju Eksportu dla firmy PRAWTECH sp. z o.o.” was signed between MARR Kraków and PRAWTECH sp. z o.o.
EXTENDED RANGE OF PRODUCTION
We would like to inform our Clients that we extended the assortment offer with stabilized pipes of diameter 75mm. Diameter 90mm will be available in the next few weeks.
ATTENTION!! STABI PIPES OF OUR PRODUCTION ARE FULLY AVAILABLE!
We are pleased to inform our Clients that we extended our offer with stabilized pipes (PPR-ALU-PPR) of 16-63mm produced in our factory. The application of these pipes in installations enables to limit the occurrence of excessive thermal elongation of plastic pipes.
Under the influence of temperature changes of a medium flowing inside the installation, pipes shrink or elongate. It refers to all the pipes made of different materials, and so it does to polypropylene pipes. Wires made of plastic are more liable to this effect than metal pipes. To reduce the factor of linear thermal elongation, a special type of PP-R pipes has been developed; it is the combination of the good aspects of plastic and metal products. They are so-called stabilized pipes.
STABI pipe consists of 5 layers: a pipe conducting the medium, stabilizing aluminum filler, covering external layer and two adhesive layers which join the whole construction. Thanks to this fact the factor of thermal elongation dropped 4 times.
The factor of linear extension λ of polypropylene pipes type 3 is:
● 0,150 mm/m*K - for one-layer pipes
● 0,035 mm/m*K - for stabilized pipes (with aluminum filler)
The good points of the system are:
- Modern system of pipes and fittings of polypropylene PP-R specially designed to assembly reliable, inexpensive and durable internal water supply and heating systems
- They can be used in new and renovated buildings
- Elements of the system are physiologically and microbiologically neutral
- Very high chemical resistance, completely corrosion free
