Ordinary carbon steel pipes will naturally have corrosion impurities deposited inside the pipe after a long service time. The final result is that the compressed air pipeline in Dalian (including the welding junction) is rotten and leaking, and the polluted air causes serious damage to the quality of pneumatic equipment, pneumatic instruments and terminal products, increases the maintenance cost of system equipment, and directly wastes a large amount of electric energy.

Practice has proved that the heavy, polluting and easy to leak seamless steel pipes and galvanized pipes have been gradually eliminated, and the PVC pipes with many potential safety hazards have gradually moved away from this industry. Instead, the new full-performance Dalian compressed air pipe is replaced. By virtue of high-end materials and production processes, it can ensure the delivery of high-quality and pure compressed air, protect the safety of gas terminals and the stability of output and quality. High performance O-ring seal can effectively prevent leakage, but the price is relatively expensive.

Design and installation of compressed air pipelines in Dalian: the compressed air transmission pipelines of domestic factories and enterprises are linear and unidirectional, which will cause the front-end jobs to work normally and the back-end jobs to have insufficient pressure and flow supply. In addition, in the installation design, the setting of the control valve in the segmented area is not considered, and the failure of one area or one equipment will cause the shutdown of the whole plant. During the installation, the drainage problem is rarely considered. The compressed air transmission pipelines of many enterprises are very messy, including those flying in the air and those buried underground, which are complex and cannot be drained. Some manufacturers also use PVC or PPR as the transmission pipeline. Due to its large expansion rate, the expansion joint is not considered. Therefore, when designing and installing compressed air = transmission pipeline, it is necessary to let the company with pressure pipeline qualification and professional design and installation to design, plan and install. In order to ensure the normal operation of production enterprises, improve efficiency, reduce costs and ensure quality.

Many people don't know what color the compressed air pipeline logo in Dalian is. Now I'll give you some popular science. Nowadays, in industrial enterprises, a large number of pipes for conveying various gases and liquids are often installed in the plant and the plant. In order to facilitate the identification of the types and states of the fluids in the pipes and facilitate the management, maintenance and safety of the pipes. Generally, the following methods are adopted for painting and marking of pipes. In order to facilitate the identification of substances in industrial pipelines, ensure safe production and avoid misjudgment in operation and equipment maintenance, this specification is formulated in combination with the actual situation of the company.
