Product Description:

1. Structure of FRP Liner Pipe Description


FRP liner pipe, the method repairing the old pipe without trenches is to put one smaller diameter FRP Mortar liner pipe into the old pipe and fixed to repair it. 


This method has advantages as following: low requirement to old pip and certain corner is acceptable, low requirements to the clearance of inner surface; easy and fast construction、and construction with little water; The stiffness and strength of FRP Mortar liner pipe are very high, which can bear the load capacity of top of pipe independently, instead of collapse due to the old pipe’s structure; The inner surface is smooth, high conveying capacity, efficient and eco-friendly, corrosion resistance, long life service, low maintenance charge and construction cost.


2. Main Features of FRP Liner 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 Liner 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:Characteristics of FRP pipes
The main pipe forming process of FRP is controlled by a computer for agricultural irrigation, as specified on the mandrel and tube glass fiber winding process the same manufacturing gel lining, according to design good linear and winding structure layer thickness, and the quartz sand and resin sand slurry mixed entangled in the structure layer. The outer protective layer. Raw and auxiliary materials: resin, short cut fiber, continuous glass fiber and quartz sand.
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:Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
1) first, apply the release agent on the molding surface of the glass lined sand pipe mold (or a transparent cellophane on the outer surface of the mold);2) after sufficient drying, the magnesium oxychloride cement with initiator (or curing agent), accelerant and other additives is evenly coated on the molding surface of the die;3) then put a good glass cloth on the glass lined sand pipe;4) then apply the magnesium oxychloride cement on the paved glass cloth and take care to remove the bubbles.5) with good magnesium oxychloride cement paste then with cut glass cloth;6) repeat this operation until the GRP sand pipe reaches the design and gauge thickness.
Q:What can be done to solve the leakage of FRP pipe?
The method of mending is hand paste. The stones must be taken away so that the pipes are restored to their original shape. If you can get into the pipe, polish it first and repair the lining.
Q:The difference between GRP cable duct and PVC cable pipe
PVC cable pipe refers to various kinds of rigid PVC pipes made of PVC resin as main raw material and various stabilizers.
Q:Is there any ventilation duct made of glass fibre reinforced plastic in Baotou?
1. Corrosion resistant FRP pipes resist acid, alkali, salt, sea water, untreated sewage, corrosive soil or groundwater, and the corrosion of numerous chemical fluids.2, good frost resistance FRP heat pipe temperature range between 40 to 80 DEG C, if the first with a special resin use temperature can reach higher.
Q:Designed to support FRP pipes, is it m or mm?
The glass steel pipe wall smooth, do not scratch the cable, socket type interface, convenient installation and connection to thermal expansion and contraction, the proportion of small, light weight and reduce installation labor, reduce the cost of installation, FRP cable protection pipe used for electric power, communication cable, in various environmental protection pipe laying cables, especially through the traffic crossing to the cable across the river the use of the bridge, under special circumstances, can fully reflect its simple construction, high strength, excellent performance, widely used in electric power, communications, transportation, civil aviation, airport infrastructure and other Domain company always adhere to the "customer first, integrity management, intentions services for business philosophy, is willing to work with friends from all walks of life to strengthen cooperation, mutual cooperation, common progress and win-win
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:What kind of project needs fiberglass pipe?
Glass fiber reinforced plastic material has the advantages of corrosion resistance, high strength, low weight, and other materials can not be compared, the use of a wide range of purposes, such as water supply, chemical raw materials, hot and hot water transportation, ventilation and so on
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.
