Application and characteristics of PPH pipe
PPH pipe is a homopolymer of vinylidene fluoride or copolymer of vinylidene fluoride and other fluorovinyl monomers with less records. It has the resin properties of resin and fluororesin. In addition to good chemical resistance, high temperature resistance, oxidation resistance, weather resistance and radiation resistance, PPH pipe also has special properties such as piezoelectric, dielectric and thermoelectric. It is the second largest product in fluoroplastic products at present.
Uses: high temperature oil for electronic components for environmental protection; Resistance capacitance and even heating are insulation and protection; Mechanical protection of various metal wires; Wire termination, splicing, end insulation, protection and reinforcement.
Features: high temperature resistance, heat resistance, medium, transparent, hard.
1. PPH pipes are non-toxic, non corrosive and non scaling, which can effectively improve the quality of the pipe network; PPH pipe has good resistance to water hammer, underground pressure of PPH pipe and pipe joint and end load, which greatly improves the safety and reliability of water supply.
2. PPH special materials for pipes have developed greatly in recent years. One important reason why PE materials are not developed early is that they are uneconomical. However, the advantages of PPH pipe after the development of high-performance polyethylene pipe have expanded the application range of PPH pipe.
3. PPH pipe has good flexibility and weldability, which makes installation more convenient, economical and safe. PPH pipe laying speed is fast, damage and maintenance costs are low, as long as the joint can bear axial load without leakage and tripping. Therefore, when laying nodes and bending, no small cost of anchors and piers is required, and the cost can be reduced. PPH pipe has unique flexibility, elongation at break of more than 500%, bending radius of 20 ~ 25 times of pipe diameter, and excellent scratch resistance. Therefore, the laying is very easy to move, bend and interpenetrate, which is suitable for many construction methods such as trenchless pipe jacking. On the other hand, the adaptability of PPH pipe to the pipe foundation reduces the requirements on the pipe foundation,
