Specification

Product Advantages:

1. Durable in use and corrosion-resistant:the surface of internal and external can resist many kinds corrosion of chemicals, crude oil. injected water and bacteria. 

2. Light weight: 24% weight of ductile iron, it is convenient for installation in the absence of heavy machinery and large tools.

3. Low cost: Internal surface can reduce friction and the cost of transporting by pump.

4. Efficient and eneray saving: GRE pipe compared with steel tube can reduce the consumption of heat.

5. The solution of pipe system: The whole FRP pipe have different size, pipe joints, pressure rating for choice.

6. The long life cycle and low cost: There is almost no maintenance costs after installation and use, and it has higher lifetime cost compared with steel tube.

Production Information:

GRE wall structure:

∙ Pipe internal liner is used for anti-corrosion
∙ Pipe structural layer is used for pipe strength
∙ 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.

Jet fire and fire-resistant experiment:

Level 3 fire-resistant experiment:

Production Method:

∙ Filament winding is used for both pipe and fitting production.
∙ The fiber glass will be winded on the mandrel after soaked into the resin. The mandrel will be rotated according to programmed mode.
∙ Multiply mandrels can be winded at the same time with one winding machine which has improved the work efficiency and guaranteed the quality.
∙ The winding of pipe fittings I flange, elbow, tee, coupling ) are made of two axis winding machines.

Production Process:

Quality Control:

Universal tester                      Differential scanning calorimeter (DSC)

Drying oven                       Fatigue tested machine

Before delivery, all pipes conduct 100% hydrostatic pressure monitoring in accordance with API standard.
