Polyethylene

Polyethylene pipes hdpe has excellent corrosion and chemical resistance. Over time, the properties of polyethylene pipe is only getting better (the smoothness of the inner surface and an inner diameter of the pipe). Low thermal conductivity of polyethylene pipe for reducing heat loss and reduces the formation of condensation on the outer surface of plastic pipes. Reduce the probability of failure during freezing liquid pipeline, as with the tube does not collapse, but increases in diameter, acquiring former size during thawing of the liquid. Polyethylene pipe has a small weight, which facilitates assembly, especially in cramped conditions. Polyethylene pipes are 5-7 times lighter than steel, so that small movements of the installation does not require the lifting mechanisms and one vehicle can carry 5-7 times more than polyethylene tubes than steel.

Significant reduction in risk of water hammer due to the relatively low modulus of elasticity. Reliability of welds in joints throughout the life of pipelines. Ease of welding. Butt welding much cheaper, easier and takes less time. The possibility of multiple rewiring at low cost. Lower labor costs during installation., Polyethylene pipe – is a reliable shield against microorganisms and bacteria, its inner layer does not give any water contaminants. And as one of the most important factors is the low cost
