Analysis on material of compressed air pipeline in Dalian

It is very important to select the right materials for compressed air pipes. There are many materials in the market. All kinds of materials can be used for compressed air. How to select the materials for compressed air pipes in Dalian?

1. The advantage of traditional galvanized pipes is that the cost is relatively low, but the disadvantage is that the equipment is relatively heavy and the labor cost is relatively large. After several years of use, the internal galvanizing damage will lead to rust and leakage at the joint, and the energy consumption is relatively large. The flow diameter of elbows and joints is smaller than the pipe diameter, which will cause pressure drop.

2. Traditional carbon steel welding reception: benefits: the cost is moderate, but the disadvantage is that the equipment is more manual than galvanized pipe, the inner wall of the pipe is simple to generate zinc, and the rust powder will flow to the downstream terminal equipment, resulting in an increase in equipment protection cost. After long-term use, the inner wall of the pipe is severely rusted, which will lead to a severe reduction in pipe diameter, an increase in pipe pressure drop, and a large energy consumption.

3. Stainless steel pipe: benefits: clean, no rust, less pressure loss, disadvantages: high cost.

4. New aluminum alloy compressed air pipe: benefits: clean, smooth inner wall, small pressure loss, convenient equipment, low labor cost, simple modification, high safety function, and ten-year warranty. Disadvantages: the cost is slightly higher than that of galvanized pipe and carbon steel pipe.
