Advantages of HDPE Piping Systems
1: Long life – PE pipes are inert and hence, non-aging when operated within their design criteria. PE pipes have been installed for many years and have minimum life expectancy of 50 years when used in accordance with the relevant standards.
2: UV and weather resistance – Because of the black pigments used, black polyethylene is very weather-resistant. Even longer exposure to direct sunlight, wind and rain hardly causes any damage to the material.
3: Chemical resistance – PE is unaffected by both internal and external chemical attacks by a wide range of acids, alkalis, ground water salts and other environmental factors. Polyethylene shows a good resistance against a broad range of media.
4: Flexibility – In contrast to traditional piping materials, PE pipes are relatively flexible. This inherent flexibility can be used to time and labour saving advantage in handling and installation, particularly in designing underground piping layouts.
5: Exceptionally smooth bore – PE does not suffer from increased surfaces roughness or internal corrosion and provides a smooth bore for the life of the piping system. Internal corrosion also causes a reduced life of steel systems which further inhabit flow.
6: Impact strength – PE has excellent impact resistance which unlike many other polymers is retained at sub-zero temperatures.
7: Environmentally compatible – PE is an environmentally compatible hydrocarbon.
8: 5 difference types of sizes – 25MM x 100M , 32MM x 100M , 40MM x 100M , 50MM x 100M , 63MM x 100M
