Q:Characteristics of FRP pipes
The main pipe forming process of FRP is controlled by a computer for agricultural irrigation, as specified on the mandrel and tube glass fiber winding process the same manufacturing gel lining, according to design good linear and winding structure layer thickness, and the quartz sand and resin sand slurry mixed entangled in the structure layer. The outer protective layer. Raw and auxiliary materials: resin, short cut fiber, continuous glass fiber and quartz sand.
Q:What are the differences between inorganic FRP pipes and plexiglass pipes, what are the advantages and disadvantages?
The inorganic glass fibre reinforced plastic wind pipe is made of unsaturated resin, and the organic is made of vinyl resin, which is strong and bears strong corrosion resistance
Q:There is a gap between the new glass fiber reinforced plastic pipe and its through wall. How can the plug be prevented from leaking through the cracks around the pipe?
Foam with polyurethane, and buy their own back, do it yourself.
Q:What's the price of fiberglass reinforced sand pipes?
Specifications: DN100--DN4000 are available.Thickness: 5mm--20mm, bothQ:28O5--9I343I/ I86+O38I+2OO7
Q:Pipe installation of glass fibre reinforced plastic pipe
The pipe connected with the transmission equipment shall be clean before installation, and the welding fixing pipe shall be far away from the equipment in order to avoid the influence of welding stress on the installation accuracy of the transmission.
Q:What is fiberglass communication tube?
Glass fiber reinforced plastic communication tube is a kind of light, high strength, corrosion resistant and burr free metal pipe. It is mainly used for protecting cables and cables.
Q:How long is the service life of glass fiber reinforced plastic pipes?
The glass fiber reinforced concrete grille is made of three kinds of polypropylene, polyvinyl chloride and ethylene propylene copolymer. The FRP grille is only half the size of the glass, saving transportation, unloading, mounting, and supporting the cost of the frame.
Q:The difference between FRP process tubes and GRP tubes
Pure glass fiber reinforced plastic pipe relative to sand pipe prices higher, in addition, the two types of pipe applications in general have obvious differences, process tubes are used in chemical plants and other places, sand pipes are used in municipal.
Q:How can FRP tanks be connected to steel tubes?
FRP pipe and glass fiber reinforced plastic fittings (three passes, elbows, etc.) generally speaking, the best way is on-site bonding, the quality is stable and convenient.
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
