GRE Pipe Description

GRE pipe is short for Glass Reinforced Epoxy pipe.

Generally high pressure FRP pipe, mainly used in oil field oil, water, polymer injection pipelines, natural gas transportation, urban drainage, drinking water pipelines, chemical industry, brine pipeline, fire pipelines and other fields.

Main Application: 

1. Pipeline of brine, water and crude oil 

2. Pipeline of polymer solution

3. Collection pipeline of crude oil and natural gas 

4. Oilfield sewage, chemical sewage and waste water disposal pipe 

5. Water distribution system 

6. Petrochemical technical pipeline

Main Features of the GRE Pipe

1. High physical-mechanical character 

2. High corrosion-resistant capability 

3. Excellent heat-Rsistant capability; the mormal working temperature is 80 degree, which can meet    the requirement of technology of oil extraction and effusion. 

4.  High-pressure-resistant capability: normal operating pressure grade from 3.5MPa to 25MPa. 

5. Light weight 

6. Long life, the designed service life is not shorter than 20 years. 

7. High flow property of medium, non scaling, non depositing wax, will not being clogged. 

8. Screw threaded connections and convenient installation.

FAQ of GRE Pipe

Q: What are the basic characteristics of the glass tube

Excellent physical and mechanical properties

Density fiberglass pipe is usually 1.8-2.1g / cm3, about 1/4 of steel, are higher than that of steel, cast iron and plastic than strength. The weight of the glass tube is generally greater than the same size steel 1/3 superior physical and mechanical properties; in addition, the thermal expansion coefficient of the glass tube and steel roughly, only 0.5% of the thermal conductivity of steel, is a good thermal and electrical insulation material.

Q: Is GRE Pipe chemical resistant with a long life?

GRE pipe has a special resistance to chemical corrosion in pipes criss-cross, dotted down environment, you can choose a different corrosion-resistant pipes according to the requirements of the medium.

Q: How are the hydraulic properties?

Water is one of the important mechanical properties of glass pipe. Hydraulic fluid excellent characteristics mean little head loss, you can use a smaller diameter or smaller power pump, thereby reducing the initial investment pipeline projects, save energy, reduce operating costs.

Q:Glass fiber reinforced plastic pipe to withstand 1.0MPa pressure, pipe wall to do how much thickness?
Glass tube wall thickness is generally determined by the manufacturer design, with stereotypes products and sequences, you can choose according to the pressure level.
Q:How is the glass reinforced septic tank and the cement drain pipe connected?
The interface can be bonded with epoxy resin adhesive. The epoxy resin strongly adhere to the two materials, but the bonding surface must be clean.
Q:What is the thickness of all types of FRP pipes?
DN200, DN150, DN100, DN80 pipe, polyurethane foam pad, 50mm thick shell, glass steel, thickness 3mm.
Q:What are the differences between FRP pipes and sand pipes in their uses?
Pressure more than 10 kg, generally do not clamp sand tube. Process tubes are mainly used in highly corrosive workplaces such as acids, alkalis, salt solutions, or high pressure pipes.
Q:What kind of material does glass steel ship honeycomb board use?
Glass reinforced plastic ships are made of glass fiber reinforced plastic honeycomb panels, and glass fiber reinforced plastic honeycomb panels are composite products developed in combination with aviation industry composite honeycomb panels technology.
Q:Glass fiber reinforced plastic pipeline to do anti-corrosion?
Glass fiber reinforced plastic itself belongs to a kind of anticorrosive material, and usually needs no antiseptic treatment. However, mainly depends on the environment and requirements.
Q:A basic overview of FRP pipes
FRP pipes are made of resin (feed water, food grade resin), glass fiber and quartz sand as raw materials and made by special process.
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!
Use a high strength resin type;
Q:Glass fiber reinforced plastic GRE pipe broken hole how to repair and repair?
Resin selection of good points, the general also line, as well as accelerators, curing agents, high-quality glass fiber cloth.
Q:Is it possible to touch the water when the glass fiber reinforced plastic pipe is polished?
For nearly 20 years of brand silicone mold manufacturers, steel and glass also played nearly 20 years, glass steel pipe interface after grinding with water is Never mind, can be polished with water to the point where you can proceed to the next step of the operation of the glass steel bonding with a clean cotton cloth to wipe clean.
