Physical properties of material:
Speific mass 0.9 ÷ 1.0 gr/cm3
Interuptional rigidity 50-60 MPa
Vicat melting temperature min 79°C
Thermal conductivity0,54 KJ/mh/°C
Linear coefficient of thermal strech 0,08 mm/m/°C
Water absorbtion 4 mg/cm2
Chemical resistance of material:
Peštan drainage PVC pipes pipes are resistant to salt water, alcohol, acids, alcaline, sulphates, aggressive gasses and all types of detargentes. On the other hand, they cannot
Be used for drainage of water with huge level of benzene, petrol, acetone.
You can see the complete table of chemical resistance in Download section.
Conecting the pipes:
Peštan PVC pipes and fittings for drainage are connected by the muffs and waterproofness of joints is being accomplished over tight rings made of EPDM rubber (EN 681) and are implemented in the muffs.
Perforation of the pipes:
Peštan PVC drainage system pipes are perforated in the following manner:
Pipe Ø110 is cut – perforated in 3 rows
Pipe Ø125 is cut – perforated in 3 rows
Pipe Ø160 is cut – perforated in 3 rows
Pipe Ø200 is cut – perforated in 4 rows
Pipe Ø250 is cut – perforated in 5 rows
Pipe Ø315 is cut – perforated in 6 rows
Also it should be highlighted that PVC drainage system pipes are perforated at 2/3 of the pipe diameter.
One of the characteristics Peštan PVC drainage system pipes is that the perforations in 2 adjacent rows do not match.
