PP-R Pipe

DETAILS

Potable water pipe networks for cold and warm water installations i.e.in residential buildings, hospitals, hotels, office and school buildings, shipbuilding
Pipe networks for rainwater utilization systems Pipe networks for compressed-air plants Pipe networks for swimming pool facilities
Pipe networks for solar plants
Pipe networks in agriculture and horticulture Heating pipes for residential house
Pipe networks for industry, transport of aggressive fluids(acids, leys, etc.) Transport of liquid foods

Polygon-pipe system is made of vestolen p9421 that is one of the best PP-R material over the world ,the material is supplied in granules precolored, special heat resistance is only one of the features of this material
,its physical and chemical properties are well suited to the transfer of potable water and in the heating field depending on pressure, it is passable to uses polygon-pipes for constant temperatures up to 70’Cwith service life of more than 50years. peak temperatures of 100 ‘C arising from short disruptions are unproblematic
Before processing, the granule undergoes specific tests in our laboratories to verify its suitability for use

To plot the hydrostatic pressure performance graph(table 1) independently of dimensions, the hoop stress (A)is calculated according to the formula
A=p(de-e)/2e P=internal pressure
DE=the external pipe diameter of pipe(mm) E=the wall thickness of the pipe(mm)
With all water carrying pipes, resistance to internal pressure is an important factor, with affects long life characteristics. To therefore assure the optimum in long life performance, straight and curved polygon-pipes have been subjected to extensive hydrostatic pressure testing at a variety of different temperatures the results.
