Q:The role of glass fiber reinforced plastic cooling towers: Thermal power plants usually have cooling towers. Water heating, high pressure gas generated by promoting the steam turbine power generation, and the remaining gas cooling.

Q:Excuse me, what standard does the glass fiber that check mechanical and electrical use accord with GB?: It is a resin based glass fiber weight layer wound on the mandrel rotating on according to process requirements, and distance evenly between the fibers as Kamiishi Eisa in the sand layer.

Q:How to connect glass fiber reinforced plastic sand pipe?: The quality of the connection of glass reinforced plastic sand pipe pipe directly affects the quality of the pipeline. The connection forms between the pipes include 3 forms: socket, butt joint and flange connection.

Q:What are the materials used in smoke exhaust pipes?: In the production of the coal mine exhaust pipe is indispensable, in underground work, because from the ground, the air is not easy to reach, easy to accumulate large amounts of methane gas, these gases will need ventilation pipe timely transferred to the ground to prevent the explosion in the coal mine ventilation pipe, the material is generally iron and plastic.

Q:How is FRP ventilation pipe made?: Coating moldingOn the surface of the mold, a transparent glass paper is fixed on the surface of the bread. When it is fixed, it is coated with a resin coating which has been adjusted. It should be even and not exposed. Then apply a layer of glass cloth and then coat with a resin coating. Each coated with a layer of resin is deposited a layer of glass cloth. The cloth lap to stagger and scraping, the outermost layer of ruibu glass surface should be coated with a layer of resin coating. After reaching the required thickness, and then deposited on the outer surface of the glass paper flatten the light pressure.

Q:What kind of material are the flanges and valves on the GRP pipe?: It's better to use plastic or polyurethane

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:Glass fiber reinforced plastic pipe to withstand 1.0MPa pressure, pipe wall to do how much thickness?: This depends on the size of the pipe diameter, the greater the diameter, the thicker the wall.

Q:Are FRP pipes still developing?: I graduated last year and like you, stay two months left, glass steel pipeline buried pipe still have comparative advantages, but in Chinese, the quality of the products before this, after all, as the steel pipe is reliable, now doing chemical, water treatment, rarely encountered glass steel pipes, steel pipes generally do not. PVC, most used, the cost is much lower than the glass steel

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.
