FAQ of FRP Pipe

Q: What can fiberglass pipe be used for?

A: Fiberglass pipes can be used for most piping applications, including: Plant and Process Piping, Firewater, Sewer (industrial & sanitary), Seawater Intake and Outfall, Desalination, Potable Water, Irrigation, Pre-insulated Chilled Water Piping, Jacking & Microtunneling, Manhole & Structural Liners, Tanks of all types (chemical & other), Conductive Piping (for hazardous areas), Offshore Piping, Fire-Resistant Piping, Abrasive-Resistant Piping, Ship and Dry Dock Ballast Piping, Marine and Subsea Piping (underwater), Air Vent Sewer Gas Ducting, Drop Shafts, Backdrops, Perforated Pipes, Oil and Gas Process Water, Downhole Threaded Tubing, High-Pressure Threaded Line Injection Well Tubing, Oil Well Casing and many more within the temperature capabilities of the resin.

Q: Are fiberglass pipes fragile?

A: Due to the elastic nature of the resin which holds the clothlike glass fibers together, fiberglass is strong and flexible. FPI products meet the rigorous "Impact Test" requirements of the international standard e.g. BS, API, ...

Q: Are fiberglass pipes an 'off the shelf' item?

A: No. FPI's fiberglass pipes are bespoke products engineered to the highest international standards and specifications.

Q:What is the structure and function of glass fiber reinforced plastic lining?
The role of FRP lining, corrosion protection, generally attached to the carbon steel container wall, can avoid the use of stainless steel, saving costs. FRP can resist acid and alkali corrosion, PH2-12 or so no problem, but not high temperature, the temperature is higher than 80 degrees, more dangerous, will dissolve.
Q:How is FRP ventilation pipe made?
Mould makingA circular or rectangular glass steel duct forming was used in the model. In the mode of circular duct production, with appropriate diameter small key tube, or wood, plywood and iron plate made of circular tube, the outer diameter is equal to the inner diameter of the circular duct; internal rectangular duct made by wood do Jackie Chan bone, then wood or plywood, steel plate fixed dry keel, the die size is equal to the inner diameter of rectangular duct. The inner mould of the round or rectangular wind pipe can be disassembled, so that it is easy to release.
Q:Excuse me, what standard does the glass fiber that check mechanical and electrical use accord with GB?
The pipe wall structure reasonable and advanced, can give full play to the role of material, to meet the premise of use strength, improve the rigidity, ensure the stability and reliability of the product. Because of its excellent chemical resistance, light weight, high strength, no scaling and strong seismic resistance, the glass steel sand inclusion has the advantages of long service life, low overall cost, quick installation, safety and reliability compared with ordinary steel tubes.
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:How to prevent the glass fiber reinforced plastic pipe from being damaged by aging or over pressure, causing the liquid to splash and hurt people
If you are afraid of the glass tube will be such a question, the weak links or parts of the local reinforcement, the conditions can, can re pipe liner, to compression, anti ageing effect
Q:Why FRP pipes for outdoor waste gas treatment equipment are selected?
Relative to the iron and steel materials such as glass, steel price is the highest, and can reach more than 25 years of life in the outdoors; other materials, such as: PP material, although very similar characteristics of steel and glass, but there is a fatal flaw: the outside is very easy to be corroded and aging, especially direct sunlight high and low temperature conditions, the service life is often less than two years.
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: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:What are the construction methods of glass fiber reinforced plastic paint anticorrosive pipes?
Epoxy coal tar coating consists of two main components with epoxy coal asphalt composition, is a (epoxy) B (curing agent) two-component coating, with good adhesion, toughness, moisture resistance, water resistance, chemical resistance, has the properties of prevent various ions through the film, and is coated with objects with the expansion of shrinkage characteristics. The paint film never falls off or cracks.
Q:Which is better, pultruded FRP square pipe with PVC?
When a strong corrosive gas, liquid or solid is conveyed in a wear-resistant pipe, there is a problem that the abrasion resistant pipeline is corroded and soon destroyed.
