Application of steel mesh skeleton composite pipe rigid steel mesh skeleton composite pipe has broad prospects in the application of water supply pipeline engineering because of its advantages of light weight, corrosion resistance, higher strength. The implementation of national standards and technical regulations has played a positive role in promoting the standardization of steel mesh skeleton composite pipe products and the standardization of application, and laid a foundation for the comprehensive promotion of the use of steel mesh skeleton composite pipe.
The characteristics of the steel mesh skeleton composite pipe are light weight, good corrosion resistance and long service life. The density of the steel mesh skeleton composite pipe is 1.4~1.6g/cm3, so it is convenient to transport and install and has high construction efficiency. The steel mesh skeleton composite pipe is resistant to various chemicals. Under normal circumstances, its service life can generally reach 30~50 years.
When the steel pipe is sleeved with the steel pipe, the steel pipe connection must be cleaned and coated with glue. After the steel pipe is heated and softened, it shall be socket inserted on the steel pipe and cooled down. The use of steel mesh skeleton composite pipeline There are three main connection forms of steel mesh skeleton composite pipeline, namely rubber interface, bonding and flange connection. In case of water leakage after construction, pipe replacement, sleeve repair bonding, glass fiber method, welding and other methods can be used for repair.
If the whole pipe section needs to be replaced if the pipe is damaged in a large area, the method of replacing the pipe with double socket connectors can be used. The solvent method can be used to deal with the leakage at the solvent bonding point. The water in the main pipe shall be drained first, and the negative pressure shall be formed in the pipe, and then the adhesive shall be injected into the pores of the leakage part. The sleeve bonding method is mainly aimed at the leakage of pipe through holes and joints. The same caliber pipe with a length of 15~20cm shall be selected and cut longitudinally. The inner surface of the casing and the outer surface of the pipe to be repaired shall be roughened according to the bonding joint method. After being coated with glue, the casing shall be tightly stuck at the leakage point.
