- 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: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 kind of project needs fiberglass pipe?
- Glass fiber reinforced plastic material has the advantages of corrosion resistance, high strength, low weight, and other materials can not be compared, the use of a wide range of purposes, such as water supply, chemical raw materials, hot and hot water transportation, ventilation and so on
- 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:How to connect glass fiber reinforced plastic sand pipe?
- Socket connection is one of the main connecting type of underground pipelines, the use of double "O" type sealing ring connection, the two sealing rings, the socket has pressure test mouth, the installation must be made up and mouth pressure test in the two ring between each interface can be arranged near side pressure test the test pressure, by design, water consumption is very small, the duration is 3 ~ 5min, with no leakage for qualified, ensure that each of the seal effect to ensure that the entire pipeline system overall pressure test success.
- Q:What are the specifications of glass fibre reinforced plastic cable pipes? What are they?
- FRP cable pipe is a new type of composite material, it mainly resin as adhesive, glass fiber as reinforcing agent, quartz sand as the supplementary material, formed by microcomputer control winding machine manufacturing, it has the strength of resistance to high pressure, weight, easy installation, safe and reliable, strong performance of insulation, corrosion can be anti corrosive the items, the anti parameter Water Leakage ability, but also has the advantages of long service life, can reach more than 50 years, because the FRP cable protection pipe set has various advantages of the industry, the performance has exceeded the same industry plastic pipe performance, it becomes popular industry engineering personnel.
- 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:What are the disadvantages of glass fiber reinforced sand pipe?
- Glass reinforced plastic sand pipe is mainly to increase the rigidity of the pipe, the relative wall thickness of pure glass steel tube, low compressive strength, shock resistance decreased.
- Q:Do I need CCC certification for ventilated GRP?
- Of course, there is also used for air conditioning duct glass fiber reinforced plastic pipe, the thickness needs at least 25MM, lined with EPS insulation foam.
- Q:What is the standard of flange coefficient for FRP ducts?
- Negotiations did not consider, people reported flange you have to consider, 15% below have been used to see your negotiating skills, there is no standard specification! The above said I have used, and now I generally talk about n yuan / square meter, including the wind pipe, pipe fittings, flanges and valve components to connect the flange are included in
