Some Common Sense About Compressed Air Pipes

When it comes to compressed air pipes, manufacturers emphasize that they are often overlooked in the configuration of production lines. While selecting the main equipment such as air compressors, filters, dryers, and gas storage tanks, little attention is paid to the pressure resistance, weather resistance, oil resistance, leakage, flexibility, and other crucial factors of the compressed air pipes. This oversight leads to various issues such as oxidation, rusting, leakage, deformation, aging, and brittleness in the compressed air pipeline. Moreover, the installation of these pipes is usually carried out by civil construction companies without proper calculation or consideration, resulting in significant pressure loss and fast flow loss. The lack of reasonable selection and investment in compressed air pipeline products in the early stages poses long-term risks for future production lines.

Manufacturers of compressed air pipes assert that more than 80% of solid particles in the system have a diameter of less than 2 microns, making it easy for them to enter the compressed air system through the air compressor and silencing filter. Once the air, containing impurities, passes through a simple filter, it undergoes compression in the air compressor. The compression process, with its high temperature and oxidation, causes a decline in the quality of the compressor lubricating oil, making it strongly acidic. When these solid particles, along with oil and water vapor, enter the compressed air pipe network system, they corrode the inner walls of traditional galvanized or carbon steel pipes. Iron, being chemically active, readily reacts with oxygen in the air, resulting in constant oxidation and rusting. This leads to the softening and loosening of the iron. Over time, corrosive impurities accumulate in the pipe, causing corrosion, leakage (including at welding positions), and air pollution. These issues severely impact the quality of pneumatic equipment, pneumatic instruments, and end products, increasing the maintenance costs of system equipment and causing financial losses. To address these problems, seamless steel pipes and galvanized pipes, which are heavy, prone to leakage, and cause pollution, are being phased out. Instead, the industry is shifting towards using full-performance aluminum alloy compressed air pipelines. These pipelines, with their superior design, material, and production process, ensure the delivery of high-quality pure compressed air, protect the safety and stability of gas terminals, and effectively prevent the sealing of high-performance O-rings.

Manufacturers of compressed air pipes note that many domestic factories and enterprises have straight and one-way compressed air pipes, resulting in normal operation at the front-end but insufficient working pressure and flow supply at the back-end. Additionally, the installation design often neglects the setting of control valves in section areas, which can lead to the failure of one area or equipment causing the entire plant to halt production and delay work. Drainage is also rarely considered during installation.

Furthermore, compressed air pipes in many companies are disorganized, with pipes flying in the air and buried underground, making it difficult to manage and drain them. Some manufacturers even use PVC or PPR pipes for transportation, disregarding the need for expansion joints due to their large expansion ratio. To ensure the smooth operation of production enterprises, improve efficiency, reduce costs, and maintain quality, it is essential to involve companies with pressure pipeline qualifications and professional design and installation expertise in the design, planning, and installation of compressed air pipelines.
