HDPE corrugated pipe: Inside diameter:200/225/300/400/500/600/700/800mm Ring stiffness:SN4/SN8 Non-pressure pipe
Buried HDPE corrugated pipe
FEATURES:
--Can be heat fused together to form a joint that is as strong or stronger than the pipe itself and is leak free.
--Produced in straight lengths up to 15meters(50 foot) long and coiled in diameters up through OD 110 mm. Coiled lengths over 300meters are available depending on size providing low cost installations
--About one-eighth the density of steel, it does not require the use of heavy lifting equipment for installation.
--Cost Effective, Long Term and Permanent---The service life for HDPE pipe is conservatively 50-100 years.
--Will not corrode, tuberculate or support biological growth.
--Has a smooth ID that does not corrode or tuberculate and maintains its flow capability over time.
--well suited for dynamic soils including areas prone to earthquake.
