Product Description:

1. Structure of FRP Split Pipe Description


FRP Split Pipe is the innovative pipe in water supply and drainage area to achieve  underground pipe’s construction without trenches, and can pass through road, railway, river, above ground structure directly. 


Due to the characteristics of good corrosion-resistance, light weight, smooth inner surface, high flow, good geographic conditions adaption etc., it has become the first choice of large and medium- sized city’s pipeline.


2. Main Features of FRP Split Pipe


1) Good corrosion resistance performance: strong corrosion resistance resin which have excellent mechanical and Processing Performance to bear the erosion of acids, alkalis, salts, raw seawater, corrosive soil, ground water and many chemical stuff.

2) Good performance in high and low temperature resistance: when temperature under 30°, FRP pipe still keeps good flexibility and high strength and can be used within temperature -50°-80°for long time, also can be used under temperature 110°with special formulated resin.

3) Abrasion resistant: The abrasion resistance performance of FRP mortar pipe is excellent. The test prove: put water loaded with amount of mud, sand, stone into the pipe and make the rotation abrasion effects comparison test. After 300 thousand times rotation, the abrasion degree is as following: steel pipe covered with tar and porcelain oil is 0.53mm; steel pipe with surface-hardening treatment is 0.48mm; FRP pipe is 0.21mm, which proves that FRP pipe’s outstanding abrasion resistance.

4) Temperature reservation: The performance of temperature reservation of FRP pipe is very good due to its low conductivity.

5) Ant-pollution after curing: no scaling, no rust and will not be attached by sea shellfish, 

fungi, microorganism in polluted water when using.

4. FRP Split Pipe Specification


1)Small specific gravity, light weight: FRP pipe’s specific gravity is 1.65-2.0 and one 1/4 compared with steel; hoop flexible tensile strength for FRP pipe is 150-420 MPa and axis tensile strength is 60-150MPa, similar to alloy steel. FRP pipe’s strength/specific gravity is 2 or 3 times compared with alloy steel so it can be designed according to customers different requirements for various pips bearing inside and outside pressure. For the same diameter pipe, FRP pipe’s weight is 1/2.5 compared with carbon steel pipe, 1/3.5 compared with cast iron pip, 1/8 compared with reinforced concrete pipe, so it’s easy for construction and transporting.

2) Fewer joints and efficient installment: Usual pipe’s length is 4-12 meters(other special length is also available according to customer demands). Single pipe is long with few joints to accelerate installment speed and reduce the fault possibility then improve efficiency of quality of construction of whole pipe.

Q:The role of glass fiber reinforced plastic cooling towers
Is specializing in the production of glass steel cooling tower, cooling tower, cooling tower, commonly known as cooling tower, glass tower, tower, main square, round, crossflow and counterflow, no filler spray cooling tower series.
Q:What are the differences between FRP pipes and sand pipes in their uses?
Glass fiber reinforced plastic sand pipe is mainly used for conveying medium and low pressure water, raw water and sewage.
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.
Q:What kind of material are the flanges and valves on the GRP pipe?
It's better to use plastic or polyurethane
Q:What can be done to solve the leakage of FRP pipe?
If you can't get into the pipe, polish it from the outside and polish it to the lining. Then make a new lining, and then use a cloth to reinforce the structure.
Q:How can I make up the broken glass fiber?
If you have to repair it, it is not impossible. Resin selection of good points, the general also line, as well as accelerators, curing agents, high-quality glass fiber cloth.
Q:How can I replace the valve on the water supply pipe?
Steel flanges, three way pipe fittings and single disk connector is connected, immediately install three branch pipe valve, and will be closed fittings and valves at the bottom with concrete pier support, in order to timely restoration of water supply.
Q:Where are the advantages of FRP pipes? Long life?
AntifoulingThe pipe surface using unsaturated polyester resin, so the surface is clean and smooth, not by sea or sewage in a shell, fungi and other microbial contamination of borers, so increasing roughness, reduce cross section, increase maintenance costs. No such pollution, long-term use clean as before.
Q:Do I need CCC certification for ventilated GRP?
Usually fiberglass, air conditioning, ventilation pipes will have insulation requirements, the general need not heat preservation.
Q:Excuse me, what standard does the glass fiber that check mechanical and electrical use accord with GB?
FRP insulated pipe is a kind of light, high strength and corrosion resistant nonmetal pipe.
