Superiority of GRE pipe
Chemical Resistance
- No damage from Oil, Seawater, Sewage, Chemicals,Exhaust gas
- Lower maintenance cost, Longer replacement period than steel
Dimensional Stability
- Thermal expansion in the circumferential & axial directions during the production sets off dimensional deformation.
Wide Range of Production
- Diameters (25A~900A) with major Classes(up to 25 bar )
- 1350A under tests for approval, Feb,2021
Light Weight
- ¼ of a weight of steel pipe
- Easier installation & handling
Low Installation Cost
- Cheaper and easier joint method than Welding one
- Lower transportation cost
Low Friction Loss
- Smoother surface with 43% lower friction loss than steel pipe
- Superior fluid flow
- Hazen Williams Factor 150
- Low maintenance cost for its semi permanent life cycle
- Superior properties than other pipe materials
- Used in oil field and marine industry, design pressure up to 25 bar.
- Higher temperature allowance up to 108 ℃
Low life-cycle cost
