Specification: Our GRE oil pipes and fittings had already certificated by API 15HR and API 15LR. SPECIFICATION: a. Diameter Range: 43.5mm - 1638mm (1" - 40") b. Rated Pressure Range:3.45- 34.5MPa c. Max. Operating Temperature: 110â?? Advantages: High Pressure GRE Pipe and Fittings is a new, toxic-free and environment-friendly pipe substituting corrugated tube, armored tube and ordinary sand-added glass-reinforced plastic pipe, which is developed by Jingbo based on imported advanced technology in 1990s. As the first of its kind in China and leading in the world, it has effectively eliminated the disadvantages of small caliber, low resistance to impact and low production efficiency and slow construction for armored tube, and high weight and cost for installation for glass-reinforced plastic pipe. While standing very strong internal and external pressure, GRE pipe is light-weighted fast in production low in cost and easy for installation and mounting/dismantling. Application: (1) City power grid construction and renovation project (2) City reconstruction project (3) Aviation airport project construction (4) Industrial zone, residential project construction (5) Traffic road , bridge construction -
