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.

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:FRP acceptance standard
Perform hydrostatic test. In order to comprehensively check the installation quality of pipes, the pressure test shall be carried out according to the test methods stipulated in the code for construction and acceptance of water supply and drainage pipe works, and the allowable seepage water quantity shall be carried out according to the standards of the steel pipe.
Q:Who knows, how is the glass reinforced septic tank connected with the municipal pipe?
If a glass fiber reinforced plastic outlet pipe is reserved, a new sewage inspection well is installed at the pipe end, and then a sewage pipe is installed to connect the reserved manhole of the municipal sewage pipe.
Q:What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe? What kind of material is good?
Other fields such as chemical industry, the product is relatively high, generally aerial or ground, even if there is high pressure, bad high risk, so even high stiffness is thicker instead of sand, in general, not afraid of high investment, the use of pure glass tube, don't use the sand tube.
Q:A basic overview of FRP pipes
FRP pipes are used in petroleum, chemical and drainage industries. Glass fiber reinforced plastic pipeline production in China has developed rapidly, and the quantity has been increasing year by year, and the scope of application and departments are becoming wider and wider.
Q:What kind of material are the flanges and valves on the GRP pipe?
The flange on the GRP pipe is fiberglass, and the flanges and pipes are one. The valve is welded with carbon steel
Q:Are FRP pipes still developing?
Glass steel complex (or perhaps not, but not absolutely continuous production mishap) manufacturing process, and China quality is not strictly controlled, low cost of pipeline as well as PVC and other engineering plastics, the high demand of the field of steel as reliable, is now used for chemical terminal treatment, city drainage etc..
Q:What are the advantages of glass fiber reinforced plastic sand pipe than HDPE pipe?
Advantages of HDPE tubes:1. It is easy to form the closed anti-seepage system by butt welding and electrofusion welding. When laying along the trench, the excavation of the trench can be reduced and the amount of the fittings can be reduced.2 、 light weight and easy to install;3 、 strong abrasion resistance and excellent hydraulic performance, the buried pipeline can be protected without outer layer. The utility model can be applied to the earthquake and the soil subsidence area of the mining area, and can be laid on the bottom of the river by immersion method.4 、 chemical resistance, resistance to internal, external and microbiological corrosion, corrosion resistance, and health. 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:Which is better, pultruded FRP square pipe with PVC?
When a material with higher temperature is conveyed in a wear-resistant pipe, there is a problem that the price of the heat-resistant steel pipe is very expensive. These problems can be easily solved after the wearable pipeline is put on the market. Widely used in wear-resistant pipe wear serious mine filling, ore concentrate and tailings transport, coal-fired power plant powder, slag, ash and other wear-resistant pipe is also very suitable.
Q:What are the materials used in smoke exhaust pipes?
The exhaust pipe in the environmental protection system is divided into: suction duct, mine gas drainage pipe, coating cloth cylinder etc. in mine industry and construction industry in the central air conditioning system of factory and office building, with dust, smoke, oil, exhaust pipe, industrial environment with comfortable air supply pipe or post industrial pollution control. The exhaust pipe in accordance with the use of this distinction is several, the exhaust pipe is generally not used in building drainage pipeline in the smoke tube, because the rain is very prone to corrosion of steel, so in general use PC tube drain pipe.
Q:What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe?
If the thickness of the pipe can meet the requirements of pressure, but can not meet the stiffness requirement, will choose to increase the thickness of sand to meet the stiffness (of course can not directly increase the sand thickness to meet the requirement of stiffness, but the cost is too high).
