Under what circumstances is the finely-made glass fiber reinforced plastic sandwich tube used?
Glass fiber reinforced plastic sand pipe is suitable for different environments. According to different corrosive environments, different anticorrosive resins can be selected, which mainly include: m-benzene unsaturated polyester resin, vinyl resin, bisphenol A resin, epoxy resin and furan resin. According to the specific conditions, they are selected respectively: for acidic environments, bisphenol A resins, furan resins, etc .; for alkaline environments, vinyl resins, epoxy resins or furan resins are used.
For solvent-based environments, resins such as furan are used; when the corrosion of acids, salts, solvents, etc. is not very serious, a relatively inexpensive m-benzene resin can be used. By selecting different resins for the inner lining, FRP pipes can be widely used in working environments such as acids, alkalis, salts, solvents, etc., and exhibit good corrosion resistance.
The reinforced glass fiber reinforced plastic sandwich pipe has the following characteristics. The centrifugal casting method is used to make high-density and void-free pipe walls, and to ensure that the glass-reinforced part is located on the outer layer of the pipe wall. 24tar; easy to connect and easy to install. The pipe end is open, and can be cut off at any place on site. It is connected with a loose collar joint made of glass fiber reinforced plastic with neoprene.
It can withstand longitudinal compressive or tensile forces in various situations; FRP sand-filled pipes have strong corrosion resistance, no corrosion treatment is required on the inside and outside of the pipe wall, and the service life can theoretically exceed 50 years without electrical corrosion problems; light weight, Only 10% of concrete pipes of the same diameter and 20% of metal pipes or asbestos cement pipes.
It has a wide range of applications, can withstand high temperatures of 70 ° C, can be used for inputting industrial water and drinking water, and can also be used for sewage and corrosive industrial wastewater or seawater. It can be installed on the ground or buried underground or even under the sea. It is installed under harsh environmental climate and terrain conditions, and the effect is good. The pipeline fittings are complete, and can be connected with pipes of any other materials, and holes can be made in any part of the pipe.
