Why is the inlet pipe of the air centrifugal compressor made of aluminum? What type of pipe should I use? Please let me know. I will be very grateful.
1 Air centrifugal compressors do not emphasize the use of aluminum pipes. This requirement may be made for specific compressors. 2 The possible purpose of aluminum pipes is: 2.1. The centrifugal compressor operates at high speed, the gaps between internal dynamic and static components are very small, and impurities are very sensitive to dynamic balance. Therefore, the inlet pipeline is not allowed to use carbon steel materials with high corrosion tendency to prevent corrosion products from entering the compressor. ； At the same time, the cost of using stainless steel is too high, so aluminum pipes are chosen. 2.2. The allowable nozzle force and torque requirements of the compressor are high. Without a load-bearing pipe bracket, the aluminum pipe is relatively light, which is beneficial to reducing the force and torque exerted on the compressor nozzle. 3 If it is the above two reasons, aluminum materials and aluminum alloys with relatively high strength and good pipe rigidity can be used.
I think the compressor pipes used for air separation are very average, and Q235A is probably enough.
I agree with the opinion above, it’s generally like this
Our company's units are also made of aluminum. I visited two factories and they were also made of aluminum. According to the original design data, in order to ensure the safety of their units. There is no detail on what kind of security it is.
