Product Performance:
The corrosion picture comparison between ordinary steel pipe and FRP pipe:
Performance comparison between ordinary steel pipe and FRP pipe:
Comparison Item | GRE pipe | Ordinary Steel Pipe |
Corrosion Resistance | Good corrosion resistance | Bad corrosion resistance |
Service Life | 20-30 years(the designed service life is more than 50 years ) | 5-10 years (nocathodic protection and preservative) |
Frictional Resistance | Smooth inner wall can reduce the accumulation of paraffin and scale;Low surface friction increase the flow of fluid velocity | The rough inner surface is easy to form scale and paraffin deposition;High surface friction leads to loss of workpressure |
Insulation Performance | There is no minimum and additional insulation material" requirement under high temperature and harsh environment | A lot of heat loss under the condition of high temperature |
Engineering Installation | Light weight, low cost of installation and transport | High weight, high cost of installation and transport |
Maintenance Fecs | It almost need no repair | Need anti-corrosive paint, cathodic protection and corrosion monitoring |
Environmental Performance | Low energy consumption in the process of productionand use | High energy consumption in the process of production and use |
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.

The utility model is suitable for conveying acid and alkaline substances, conveying sewage, natural gas, gas and other substances;5, good environmental adaptability and frost resistance. It can be used in indoor and outdoor water supply pipelines.6, long service life, with more than almost 50 years of service life;7, easy to recycle
- Q:Why FRP pipes for outdoor waste gas treatment equipment are selected?
- Glass fiber reinforced plastic properties: light and hard, non conductive, stable performance, high mechanical strength, less recycling, corrosion resistance.
- Q:How to improve the compressive strength of waste glass fiber reinforced plastic profiles (such as square tubes) should be started with resin, curing agent, glass fiber or other aspects!
- Using reinforced materials of good quality, reinforced materials without alkali glass fiber are used;
- Q:Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
- 1) FRP reinforcement, length of rectangular duct is greater than 900mm, and the pipe length is more than 1250mm, should be strengthened. The reinforcement shall be made of bulk material (fiber reinforced plastic) and reinforced plate at the maximum stress, so as to increase the modulus of the section and increase the overall strength of the tube. FRP reinforcement can also be in the wind pipe production is completed, the treated metal or other corrosion resistant material for reinforcement, reinforcement and FRP as a whole, and with the same pipeline body cementitious material sealing gap2) hobas pipe surface thickness of the slurry to flatten the glass fiber mesh cloth texture is appropriate (see:). No dense air holes and grout leaks are allowed on the wall of the pipe to avoid the stress concentration under the bending tensile stress (positive air pressure) and the bending compressive stress (negative wind pressure).3) FRP pipe and flange corner should transition arc, transition radius to wall thickness of 0.8 ~ 1.2 times, improve the bearing capacity and the cantilever flange to avoid stress concentration. Fiberglass mesh shall be extended to the duct at the flange of the duct.
