Specifications

API Hot Spring Pipe 
1.Standard:API,ASTM,ISO,GB, etc 
2.Anti-corrosion & high strength 
3.Long service time 
4.Low costs

GRE (Glass Reinforced Epoxy)

Some times, GRE and FRP/GRP (Fiber/Glass Reinforced Plastic) are regarded as the same

material with different names, but in most cases, since GRE choice epoxy resin as material, 

it has stronger performances.

 

It is the thermosetting plastic products combining the reinforced material of fiberglass roving with the base material of epoxy resin
It is made by mechanical filament wound process controlled by computer. 
So it is a kind of composite material. 

 

The GRE pipe offers a unique combination of chemical resistance, size stability, high strength, and thermal/electric non-conductivity.


So the GRE pipe can be used in the fields of chemical anti-corrosion, construction, electric insulation, power development etc.

  

Features:

1. Anti corrosion

2. High strength, more safety

3. More than 30 years service life

4. Light weight, easy installation and keeping cost

5. Flexible design and shorter reform term

6. No medium pollution

Q:Characteristics of FRP pipes
(1) corrosion resistance: chemically inert material, excellent corrosion resistance, and can choose different corrosion resistant pipes according to the transmission medium.(2) strong mechanical strength: good water pressure resistance, good resistance to external pressure and impact strength, and piping and fittings can be designed according to the required pressure.(3) temperature adaptability: the use of temperature range: greater than -70 degrees Celsius, less than 250 degrees Celsius, under the freezing medium, the pipe is not split.(4) the resistance of the fluid is small: the pipe wall is smooth, the roughness coefficient is 0.0084, and the pipe diameter can be reduced under the same flow rate.(5) light weight, long life: light quality, convenient transportation, low construction cost, no maintenance, and the service life of more than 50 years.(6) maintain the water quality: non-toxic, conveying drinking water, can maintain long-term water quality sanitation. The application of FRP: the drinking water distribution pipe and line pipe conveying
Q:Glass tube has different diameters with different prices. Who can elaborate?
The standard for FRP pipe execution is GB21238-2007
Q:FRP acceptance standard
Check radial deflection values. In accordance with the requirements of the specification, the FRP pipe installation shall be completed within 24h, the initial radial deflection of the pipe shall be tested, and the pipe shall not be raised, flattened or otherwise mutated.
Q:What is the compressive strength of all kinds of FRP materials?
Heat resistance, frost resistance: at -30 DEG C, still has good toughness and high strength, can be used for a long time in the range of -50 DEG C 80 DEG C, the temperature of resin with special formula can be more than 110 DEG C. 4) of light weight, high strength, convenient transportation and installation by fiberglassreinforcedplastic pipe winding fiber production, the proportion of 1.65 - 2, 1 / 4 only of steel, but the glass steel hoop tensile strength is 180 300MPa, the axial tensile strength of 60 150MPa, similar to alloy steel. Therefore, its specific strength (strength / density) is 2-3 times that of alloy steel, so that it can be designed according to different requirements of users to meet all kinds of internal and external pressure requirements of the pipeline. For the same diameter of single FRP tube, only carbon steel (steel plate) 1 / 2.5, 1 / 3.5 of the cast iron pipe, about 1 / 8 of prestressed reinforced concrete pipe, so the transportation is very convenient for installation. The GRP pipe is 12 meters per length, and can be reduced by 2/3 from the concrete pipe. The socket connection mode of the utility model has the advantages of quick and simple installation, low hoisting cost and improved installation speed. 5) small friction resistance, high transport capacity: glass tube wall is very smooth, roughness and friction resistance is very small. The roughness coefficient is 0.0084, while the n value of concrete pipe is 0.014, and the cast iron pipe is 0.013. Therefore, glass fiber reinforced plastic pipe can significantly reduce the loss of fluid pressure along the course and improve the conveying capacity.
Q:Raw material and mix ratio of inorganic glass fibre reinforced plastic wind pipe
In order to improve the quality of glass.Advanced technology may be used.The ratio seems to be 1 to 0.001. Pretty much within this range.
Q:How is FRP ventilation pipe made?
It should be noted that the flange and the duct shall be a whole and shall be at right angles to the axis of the wind pipe. The flanges of the air duct and its pipe end shall be formed together during the coating process. Glass fibre reinforced plastic pipe flanges shall conform to the provisions of table 5-21.
Q:Uneven settlement of the foundation, can lead to glass fiber reinforced plastic underground water pipes burst, what is the principle?
Dislocation will cause the pipe to burst. The pressure is different, and the pipe will burst
Q:How long is the service life of glass fiber reinforced plastic pipes?
Glass fiber reinforced plastic grille can reduce power consumption and simplify management. Galvanized grille plate adopts high efficiency and low resistance water collecting device, floating water rate is less than 0.001%, environmental protection is the best. The galvanized grating plate has the advantages of advanced structural design, optimum matching of gas and water, and sufficient heat exchange, with the same level in foreign countries and superior output. The company has a realistic, innovative research team. The galvanized grille fan adopts a tensile type of strong wind blade and long space, which is more stable when the fan is running, thereby reducing noise and greatly improving the cooling efficiency. Successively in Shanghai, Guangdong, long-term and domestic famous universities, research institutes cooperation. Hebei, Qingdao and Beijing have additional production bases and service liaison points. Willing to work with new and old customers to create a beautiful today, Chinese and foreign.
Q:Which is better, pultruded FRP square pipe with PVC?
When abrasive materials are transported in the wear-resistant pipes (such as ash, coal dust, ore fines, etc.), there is a problem of rapid wear and tear of the wear-resistant pipes, especially the rapid wear of the bent pipe.
Q:How to connect glass fiber reinforced plastic sand pipe?
Socket connection is one of the main connecting type of underground pipelines, the use of double "O" type sealing ring connection, the two sealing rings, the socket has pressure test mouth, the installation must be made up and mouth pressure test in the two ring between each interface can be arranged near side pressure test the test pressure, by design, water consumption is very small, the duration is 3 ~ 5min, with no leakage for qualified, ensure that each of the seal effect to ensure that the entire pipeline system overall pressure test success.
