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.
