Description
High Pressure GRE Line Pipe
GRE Line Pipe mainly serves the following:
Transportation line for oil, gas, water and other fluids in Oil & Gas and PetroChemical.
Being of excellent performance on
Corrosion resistance;
Insulation;
Easy installation;
Light weight (the weight is 30% of the same size steel pipe);
Fluidity (the inner wall roughness is 10% of the same size steel pipe);
Low thermal conductivity (thermal conductivity is 0.6% of the steel pipe).
Diameter: DN40-DN900;
Pressure rating: 3.45-34.5MPa;
