The advantages of limited-product

1, good insulation performance, low heat loss, heat loss is only 25% of the traditional pipe, long-term operation can save a lot of energy, significantly reduce the energy cost;

2. With strong waterproof and corrosion resistance and high mechanical strength, it can meet the thermal stress requirements of direct buried laying without compensation;

3, more than 30 years of service life, the correct installation and use of pipe network maintenance costs are very low;

4. There is no need to attach pipe trench, which can be directly buried underground, convenient and quick construction, and low comprehensive cost;

5. An alarm system can be set up to automatically detect the leakage fault of the pipe network and give an automatic alarm with high safety and stability;

6. The products are buried underground, which is conducive to environmental beautification and town planning.
