FAQ of FRP  Pipe

Q: What is fiberglass composite?

A: Fiberglass composite is a laminate made from glass fibers or filaments and thermosetting resin. It is commonly known as RTRP, RTMP, FRP, GRP, GRE and GRV.

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:Is it useful to make gas pipelines with glass steel pipes? Or the idea that the technology is mature?
I don't think it's enough, because the strength of FRP is not enough, it can easily be brittle and easily perforated in the field for a long time!
Q:How to repair and repair the broken hole of GRE glass fiber reinforced plastic pipe?
1, clean up the broken hole around, clean; 2, find a piece of iron or glass steel film, slightly larger than the broken hole;
Q:Are FRP pipes still developing?
Glass steel complex (or perhaps not, but not absolutely continuous production mishap) manufacturing process, and China quality is not strictly controlled, low cost of pipeline as well as PVC and other engineering plastics, the high demand of the field of steel as reliable, is now used for chemical terminal treatment, city drainage etc..
Q:The difference between GRP cable duct and PVC cable pipe
The biggest difference is that the material is different, and the other areas of use are different
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:Raw material and mix ratio of inorganic glass fibre reinforced plastic wind pipe
Glass, reinforced with filler, the general ratio is 1 to 0.001
Q:What is the heat preservation of the plumbing pipe now? I'd like to use fiberglass Seek help from a master
I think that you can use magnesium aluminum silicate pipe because this product is suitable for oil pipeline and pipe insulation insulation general insulation are using the products and for foam asbestos products no pollution of construction
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:How to improve the compressive strength of waste glass fiber reinforced plastic profiles (such as square tubes) should be started with resin, curing agent, glass fiber or other aspects!
Ensure the solidification of glass steel products in a reasonable range, in general, glass fibre reinforced epoxy resin material curing degree if the use of amine curing agent, the best curing degree in the range of 135 degrees --150 degrees, polyester resin, Mohs hardness of about 60 is OK.
Q:What is the stiffness of FRP pipe?
The ring stiffness is the comprehensive parameter of the tube's resistance to external pressure. Obviously, the choice of ring stiffness is one of the keys to ensure the safe operation of plastic underground drainage pipe under the external compressive load. If the ring stiffness of the tube is too small, the tube may undergo excessive deformation or buckling failure. On the other hand, if the ring stiffness is chosen too high, the excessive cross section moment of inertia must be used, which will result in too much material and too high cost.
