The difference and advantage between PPS air duct and the same kind of pipe
PPS air duct and PP pipe are better anticorrosive pipes, but the price of PPS air duct is much 太阳2登录网址 expensive than PP pipe. Many people have doubts. According to the price comparison, we must think that it is the most cost-effective to choose PP pipe, which is also non-toxic, tasteless and corrosion-resistant. The price of PP pipe is cheaper than PPS air duct. In fact, it is not understood that PP pipe and PPS air pipe are two kinds of pipes with different application environments, and precisely speaking, the comprehensive performance of PPS air pipe is better than PP pipe, and PPS air pipe is not recyclable, which is equivalent to one-time products. Through this point, we can explain the reason why the price of PPS air pipe is 太阳2登录网址 expensive than PP pipe.
In fact, another very important reason is that the chemical resistance of PP pipe and PPS air pipe is also different. In a word, the acid resistance of PP pipe is better, and the alkali resistance of PPS air pipe is better, including the piezoelectricity, dielectric and other special properties that PP pipe does not have. Strictly speaking, the application environment of these two pipes is also distinguished. PP pipe is mainly used in industry, conveying some medium with chemical composition, such as pharmaceutical plant, oil refinery, sewage treatment plant, chemical plant, etc.
PPS air duct is 太阳2登录网址 used in the food industry, according to the importance of food safety, in terms of the selection of pipes, it is also very particular, the transportation pipeline of drinking water is definitely the first choice of PPS air duct, the safety level of PPS air duct is currently known to be higher in pipes, in order to ensure the safety of food, it is reasonable to choose PPS air duct which is 太阳2登录网址 expensive than PP pipe. Of course, due to the excellent performance of PPS air duct, it is also widely used in the microelectronics industry, such as the protection of electronic components, mechanical accessories and resistance capacitors in high temperature and oil environment, the insulation protection of thermocouples, and the protection, reinforcement and insulation of open end, connection, end, etc. Generally speaking, PP pipe has a good popularity, PPS pipe is expensive but has a good pertinence.
A good pipe should not only be good economic, but also have a series of advantages such as reliable interface, simultaneous interpreting of materials, impact resistance, cracking resistance, aging resistance, corrosion resistance and so on. Compared with traditional pipes, a PPS wind pipe has the following advantages:
(1) reliable connection: the pipeline system is connected by electric melting, and the strength of the joint is higher than that of the pipeline body.
(2) good impact resistance at low temperature: low temperature embrittlement temperature is very low, which can be safely used in the temperature range of - 60-60 ℃. During winter construction, due to the good impact resistance of the material, the pipe will not be brittle.
(3) good stress cracking resistance: PVDF has low notch sensitivity, high shear strength and excellent scratch resistance, and also has outstanding environmental stress cracking resistance.
(4) good chemical resistance: PPS wind pipeline can withstand the corrosion of various chemical media, and the chemical substances in the soil will not cause any degradation to the pipeline. Therefore, it will not rot, rust or electrochemical corrosion; in addition, it will not promote the growth of algae, bacteria or fungi.
(5) aging resistance and long service life: pipes containing 2-2.5% evenly distributed carbon black can be stored or used outdoors without damage due to ultraviolet radiation.
(6) good wear resistance: compared with steel pipe, the wear resistance of HDPE pipe is 4 times that of steel pipe. In the field of mud transportation, compared with steel pipe, PPS air pipeline has better wear resistance, which means HDPE pipeline has longer service life and better economy.
(7) good flexibility: the flexibility of PPS air duct makes it easy to bend. In engineering, it can bypass obstacles by changing the direction of the duct. In many cases, the flexibility of the duct can reduce the consumption of pipe fittings and the installation cost.
(8) small flow resistance: PVDF clean pipeline has smooth internal surface. Smooth performance and non adhesion characteristics ensure that PPS air pipeline has higher transportation capacity than the traditional pipe, but also reduce the pressure loss and water transmission energy consumption.
(9) convenient handling: PPS air duct is lighter than concrete pipe, galvanized pipe and steel pipe. It is easy to handle and install, with lower manpower and equipment requirements, which means the installation cost of the project is greatly reduced.
