GRP pipe is suitable for different environment, according to the different corrosion environment, can choose different anti-corrosion resin, including: isophthalic unsaturated polyester resin, vinyl resin, bisphenol A resin, epoxy resin and furan resin, were selected according to the specific circumstances of the acidic environment, the resin, bisphenol A furan resin; in alkaline environment, vinyl resin, epoxy resin and furan resin; used environment of solvent, selection of furan resin; when acid, salt, solvent corrosion is not very serious, you can choose to use isophthalic resin cheaper. Through the selection of different resins on the inner lining, the FRP pipeline can be widely used in the working environment, such as acid, alkali, salt, solvent, and so on, which shows good corrosion resistance.
Reinforced GRP sand pipe has the following characteristics:
1, application of centrifugal casting pipe wall by Qi high density void free, and ensure that the glass reinforced in the outer tube wall of the pipe wall of the inside and outside surface of precise and smooth, not attached to scale, small head loss, pipe high strength, pressure can reach 2O ~ 24tar;
2 、 convenient connection and easy installation. The end of the pipe is an opening and can be cut off on the spot at any place, and the loose collar joint made of neoprene and the glass fiber reinforced plastic is connected, and the longitudinal compressive force or the tensile force can be taken under various conditions;
3, glass reinforced plastic sand pipe corrosion resistance is strong, inside and outside the pipe wall without anti-corrosion treatment, the service life can theoretically more than 50 years, there is no electrical corrosion problems;
4, light weight, only the same diameter of concrete pipe l0%, metal pipe or asbestos cement pipe 20%;
5, a wide range of applications, resistant to high temperature of 70 DEG C, can be used to enter the industrial water and drinking water, can also be used for sewage and industrial waste water or corrosive water, can be installed on the ground or buried in the ground or under the sea, can be installed in a variety of harsh climate and terrain conditions, the effect is good;
6 、 pipe fittings are complete, can be connected with any other material pipe, and can be opened at any part of the pipe.
