1. Better corrosion resistance & longer service life

2. Compared with steel pipe , the specific gravity of GRE pipe is only about 1/4 of steel pipe & it has higher specific strength, while the thermal conductivity coefficient is only about 0.5% of steel, making it a good heat transfer insulator.

3. Lower installation & maintenance costs. GRE pipe does not require special anti-corrosion treatment, which reduces initial investment & later  maintenance costs. The pipe is lighter in weight & can be connected without welding. Compared with steel pipe,the installation cost is lower.
