Why do pneumatic ball valves need stainless steel pipe fittings for connection?
Recently, some customers did not understand why the user required stainless steel 304 pipe fittings and connectors when purchasing pneumatic ball valves. Here, let’s ask Xiao Bian to explain the difference between stainless steel 304 pipe fittings and plastic PU pipes on pneumatic ball valves.
In the cold places in the north of our country, when the temperature reaches tens of degrees below zero in winter, PU pipes are easy to freeze and even crack, especially for pneumatic ball valves used outdoors. Stainless steel 304 pipes and joints must be used in such cold places.
Stainless Steel Pipe and PU Pipe of Advantages and Disadvantages
The advantage of stainless steel pipe is that it has beautiful appearance and is of high grade. It can be used normally in low temperature and high temperature areas, and its service life is relatively long. However, the installation is troublesome, and special tools need to be used to bend the pipe. Moreover, the cost of raw materials is much higher than that of PU pipe, and the fixed volume is larger, and the packaging cost is also higher.
The advantage of PU pipe is that it is easy to install and low in cost. No special tools are needed, and everyone can install it at a glance. It can be used as long as it is equipped with a quick connector. However, it is easy to harden. When it is used in high and low temperature environments, it is easy to leak air and has a relatively short service life.
Considering the reliability and practicability, more than 90% of the pneumatic ball valves produced by Shanghai Gaocheng Valve are installed with stainless steel pipes and joints, and only a small number are installed indoors and connected with PU plastic pipes. Dear, please choose according to your actual use. I hope my explanation will help you a little. See you next time.
