Q:What are the posts of glass fiber reinforced plastic sand pipe and the corresponding occupational hazards and protection?

Glass reinforced plastic underground sand pipe has long service life without operation and maintenance, which is the biggest advantage of this product. Since pipe jacking is an underground concealed project, its service life is undoubtedly the very important consideration of decision-makers. The service life of glass fiber reinforced plastic sand pipe jacking is more than 50 years, which is incomparable to the products such as steel pipe, concrete pipe and so on.

Q:Is it useful to make gas pipelines with glass steel pipes? Or the idea that the technology is mature?

There are ideas, corrosion problems resolved, you can consider the use of casing, you have to consider the length of the pipeline, glass tube links. And that's the pressure on the glass.

Q:How is FRP ventilation pipe made?

Solidification strippingThe coated FRP pipe can be released after a period of constant pressure to a certain strength. When the mold is released, the pre - prepared ejection support points shall be removed to separate the mold from the molded air pipe and then to exit the mold. Finally, remove the glass paper on the inside and outside surface. Air duct after stripping. Excess parts or burrs can be polished by hand cutting machine or sand grinder.

Q:What is the thickness of all types of FRP pipes?

The standard effective length of the tube is 6m and 12M, and the production methods include fixed length winding process, centrifugal casting process and continuous winding process of three kinds. Classification can be carried out according to the product process method, pressure grade PN and stiffness grade SN.

Q:What are FRP pipes used for making? What raw materials?

The glass tube with its unique strong corrosion resistance, smooth surface materials, low energy consumption and long service life (50 years), convenient transportation and installation, maintenance and many other advantages of low cost and low cost in electric power, petroleum, chemical industry, papermaking, city water supply and drainage, sewage treatment plant, seawater desalination, gas transportation other industries have been widely applied.

Q:How can I replace the valve on the water supply pipe?

Can be arranged according to the construction plan, the first excavation processing and then steel flange three pipe production, water supply operation again when all the preparatory work is completed, and according to the steel flange three pipe length decided to cut the glass steel pipes length;

Q:What are the disadvantages of glass fiber reinforced sand pipe?

Not agree with the recommended answer, the same thickness of glass fiber reinforced plastic sand pipe and process tube, process tube stiffness is not low (can be calculated). The effect of sand inclusion is mainly to reduce the cost.

Q:What kind of diamond saw blade for cut glass steel pipe?

It is better to use ceramic stem slice, thin, toothless and wear less.

Q:Galvanized steel sheet and inorganic glass fibre reinforced plastic pipe are calculated according to this norm or norm

1, the quota valuation, wind pipe materials, such as the "loss" of galvanized steel has been included in the quota content, including the lap and material loss, making the wind pipe.2, when calculating the actual material, it can be calculated according to the calculation area of the air pipe * (1+ fixed loss) = the actual amount of material used.

Q:How long is the service life of glass fiber reinforced plastic pipes?

Glass fiber reinforced plastic grille can reduce power consumption and simplify management. Galvanized grille plate adopts high efficiency and low resistance water collecting device, floating water rate is less than 0.001%, environmental protection is the best. The galvanized grating plate has the advantages of advanced structural design, optimum matching of gas and water, and sufficient heat exchange, with the same level in foreign countries and superior output. The company has a realistic, innovative research team. The galvanized grille fan adopts a tensile type of strong wind blade and long space, which is more stable when the fan is running, thereby reducing noise and greatly improving the cooling efficiency. Successively in Shanghai, Guangdong, long-term and domestic famous universities, research institutes cooperation. Hebei, Qingdao and Beijing have additional production bases and service liaison points. Willing to work with new and old customers to create a beautiful today, Chinese and foreign.
