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 o ther 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
