Oil Concentration Pipe

GRE pipe is a lightweight, high strength and corrosion resistant non-metallic pipe. Winding glass fiber which has been immersed in epoxy resin on the core according to technology requirements. After curing and demoulding, finished GRE products is done. Its pipe wall structure is reasonable and advanced, which can give full play to the role of the material, on the premise of meeting the use of strength, improve the degree of steel, to ensure the stability and reliability of the product.

Products Applications:

Oil & gas-onshore

Crude oil gathering line

Injected water

Process pipeline in station

LNG pipeline

Ballast water

Cooling water

Fresh water pipe

Transport sewage

Underground pipe and casing pipe

GRE pipes have passed jet fire resistant test and L3 fire-resistant test:

Standards:

AWWA M45 FRP pipe design

IMO Res.A752(18) Specification for application of plastic piping to Marine equipment

ASTM---F1173 Specification for application of thermosetting resin fiberglass piping systems to Marine equipment

Production processes:

Production Information

Pipe internal liner is used for anti-corrosion

Anti-UV protection can used in pipe external to resist UV & the weathering exposure and environmental protection

If high flow conducting electrostatic discharge need, GRE pipe can be used to conduct harmful static electricity discharged in the danger zone

In the fire, protective layer meet the fire resistance performance of protection box, required by firefighting, and produce less harmful gas.
