Advantage of the pre-insulated pipe   

1.	good insulation properties
2.	low heat loss
3.	heat loss is 25% of the traditional pipe.
4.	energy saving
5.	about 30 yeas move the service life, low cost
6.	has a strong waterproof and corrosive resistance and high mechanical strength
7.	no attached trench ,can be directly buried in the ground or water.
