1. Structure of FRP Process Pipe Description
1) The material of moulds will be depended on your requirements on products and total quantity. Usually we use steel 45#, 60#, Chrome 40, P20 or 718.
2) Core and Cavity surface with Chrome plating can prolong mould life and surface glossy of products.
2. Main Features of FRP Process Pipe
Corrosion resistance: Choose different corrosion resistance pipe according to the transferring media in complicated environment.
Pressure resistance: Made the pipe and fittings according to technical requirements. Testing the heat and pressure with 1.5 times of demanded technical pressure. The acceptable lowest temperature is minus 70 degree and highest temperature is 250 degree.
Good transparency and can be colorful after improvement; High thermal conductivity can be enhanced after improve the temperature preservation.

4. FRP Process 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: 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: 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: Mending method for glass fiber reinforced plastic pipe
- Tip: if glass fibre reinforced plastic pipe is broken, it is suggested to replace it with new pipe.
- Q: What is the difference between glass tube, sand pipe and glass tube?
- 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). Sand sandwiched glass fiber reinforced plastic pipes only have more than one sand sandwiched with glass fiber reinforced plastic pipes, and sand layer can be understood to replace glass fiber with quartz sand. The sand pipe with the same thickness is compared with the glass fiber reinforced plastic pipe, but the sand holding pipe is cheap, but the strength is poor; and the glass steel pipe is opposite.
- Q: What are FRP pipes?
- The glass steel base material and reinforcing material composition, because of different base material we have called GRE, some called GRP, the matrix material is generally resin reinforced material is glass fiber, adding other raw materials in the production process to obtain more excellent performance, such as adding graphite or carbon fiber can be obtained antistatic, using phenolic resin as matrix material, can obtain very high temperature resistant ability, can withstand instantaneous temperature of 3000 degrees celsius. The glass steel pipe in recent years in the shipbuilding industry is very popular and special attention, such as ship oil tankers, chemical tankers, offshore platform and ship ballast system, at the request of foreign shipowners in the use of glass steel pipes and fittings, its advantages in addition to the static electricity can guide, there are many advantages. Such as light weight, FRP pipe the same general size is only 35% of the weight of the steel pipe, is resistance to seawater corrosion, general steel and glass pipe manufacturers can promise: 50 years. Its disadvantage is that the pressure can bear the bottom and the modulus of elasticity is low. But it's enough in the ballast system. The GRE tube is better than the GRP tube in tensile strength and pressure resistance, so some people refer to the GRE tube as the high-pressure FRP pipe.
- Q: Why more and more people choose FRP pipe?
- And the price ratio of FRP pipe is not much cheaper, and although the hardness of concrete pipe although FRP pipe to be hard, but the toughness and tensile strength is poor, the pressure is not good, and the cost is expensive, because more and more people use glass steel, and the price is expensive, with longer life.
- Q: What epoxy resin is used for anticorrosion of pipeline glass fiber reinforced plastics?
- 3PE has been anti-corrosion principle, there is no need for anti-corrosion, but now the domestic situation. Directional drilling pipe cannot be detected and repaired, the anticorrosion layer cannot have serious damage to the pipeline, long-term safety operation, it should be required for coating directional drilling: scratch resistance, abrasion resistance, impact resistance, high hardness, strong adhesion and pipeline, corrosion resistance, water resistance have a good soak, matching and cathodic protection system.
- 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: Can FRP pipes be used in heating pipes?
- FRP pipes are generally not used in heating pipes, because the use temperature of FRP pipes is limited, as detailed below:1. universal unsaturated polyester FRP can only be used for less than or equal to 60 degrees (HG/T20696-1999)2. bisphenol A unsaturated polyester FRP can only be used for less than or equal to 100 degrees HG/T20696-1999)3. vinyl unsaturated polyester glass fiber can only be used for less than or equal to 120 degrees HG/T20696-1999)4. epoxy FRP can be used for less than or equal to 90 degrees HG/T20696-1999)5. glass fiber reinforced plastic sand holding pipes can only be used for less than or equal to 50 degrees (GB/T21238-2007)
- Q: What is the elastic modulus of glass fiber reinforced plastic?
- If so, the modulus of elasticity is 72000MPa, and the glass is isotropic, so the modulus of elasticity in the three directions is the value.
