Introduction of GRE Pipes for Oil Exploration and Transportation
Lightweight and easy to handle and install, GRE pipes have a smooth internal surface that reduces friction and enables a high pipe flow capacity. The low thermal conductivity of GRE pipes relative to steel (only one percent of steel values) minimises the cost of insulation and heat loss. Another major benefit of GRE pipes is that, once they are installed, they are virtually maintenance-free.
GRE pipes are well suited for environments where corrosion resistance is required at a reasonable price.
Main uses include petrochemical process lines, oil and gas systems, fire-fighting systems, offshore and onshore systems, and ship and marine applications.
GRE pipes are available in diameters ranging from DN 25 to DN 1,000 mm.
Advantage of GRE Pipes for Oil Exploration and Transportation

FAQ:
1, Connection of the GRE Pipes:
API screw thread seal with aquaseal connection of 8 round or 10 round;
2, Standard of the GRE Pipes?
API Spec 15HR
3, Fittings supplied?
All of the standard GRE fittings are matched well with the original pipes. Most of the fittings are produced by filament winding process.all fittings should be ordered as per thread specification and design pressure.
