Properties of HDPE Drain Pipes

HDPE Drain pipes and fittings has extraordinary chemical and impact resistance, as well as a high flexibility level amongst other highly regarded properties:

Resistance to high temperatures – HDPE guarantees resistance to temperatures of up to 100°C and is therefore suitable for carrying waste water from washing-machines and dishwashers.

Elasticity –HDPE is suitable for use in buildings exposed to vibrations in earthquake prone areas and across expansion joints.

Resistance to UV rays – Thanks to the addition of a percentage of carbon black, HDPE can be installed in the open air without deterioration due to UV exposure.

Ease of jointing using welding – HDPE joints are welded (both butt and electrofusion welding), ensuring a completely airtight pipe system.

Low weight – HDPE is lightweight, making it easy to transport and handle.

HDPE cannot be glued – Owing to its high resistance to chemical agents, HDPE cannot be glued.

Resistance to low temperatures – The elasticity of HDPE makes pipe systems resistant to failure even when frozen.

Impact resistance – Thanks to its high elasticity, HDPE is resistant to impact to -40°C; meaning there is no problem carrying out installation at low temperatures.

Absence of clogging – The smooth surfaces of HDPE allow a perfect downflow of every kind of waste water and self-cleaning of the pipe systems.

Behaviour in presence of fire – HDPE does not emit any toxic gas during combustion.

HDPE fittings: rubber rings –Even if the rubber rings in the push-fit sockets and expansion sockets are slightly wet by waste waters, they are resistant to all the chemical agents. They are made of an elastomeric material which guarantees tightness and durability, even under extreme conditions.
