Advantage and characteristics:
high mechanical strength and good corrosion resistance
1. Project cost can be reduced by 25%.
2. Reduce heat loss, energy saving, heat preservation effect
increased by 4 ~ 9 times and the water absorption rate is very low,
about 0.2kg / m2.
3. Anti-corrosion, good insulation performance, long service life:
Raw material HDPE, with high mechanical strength and good corrosion
resistance, effectively prevent the infiltration of water and oil,
service life is up to 50 years, three or four times more than the
traditional outer protection tube.
