Chemical resistance: not corrupted by sewage, waste water and chemical physic, no corrosion due to the ulcer in the soil.
Shock resistance: the pipe wall adopts type structure, shock resistance, pressure resistance, no broken even groundsill falling down. The strong rebounding capacity, good adaptability to any groundsill.
Ageing resistance: the pipe is black normally, it can bear the direct sunshine during storage and construction.
Cold resistance: the pipe doesn freeze into crack and doesn expanse into water leakage.
Light weight: easy transportation, easy construction, its weight is only one eighth of cement pipe. Only need navvy for pipe burying, not need the large scale device.
Convenient connection: the pipe can be jointed at outside of channel firstly, then can be pushed into channel. At city water discharging engineering, the engineering time and engineering cost can be reduced.
Excellent abrasive resistance: its abrasive resistance is better than steel pipe and cement pipe. Strong passing and transporting capacity for life water and waste residue.
Excellent water draining and flowing performance: smooth inner, the friction is reduced, quick water draining.
Economy: low price of raw material, low cost of construction, management and maintenance.
Environmental infection: HDPE is a material without any toxicity, innocuity to the soil, it can be regenerated to use thoroughly.
