What should be noted when designing compressed air pipeline

When designing the compressed air pipeline, the air velocity in the pipeline should be below 30m/s first. This velocity is assumed to be at a pressure drop of 10% as the air moves through the pipe. If this speed is exceeded, the pipe size should be increased appropriately. The inner of the pipe shall be smooth and the small bending radius of the metal pipe shall be more than three times the diameter of the pipe.

Compressed air piping manufacturers recommend that plastic pipes be protected from mechanical and thermal damage and that the number of connections should be kept to a minimum. The installation position of the pipeline shall not affect the adjustment, repair and replacement of components of the pneumatic system and the operation of the device. Pipeline with length greater than 5m shall be installed along

Combined with the existing problems and deficiencies in the use of compressed air in carbon plant, the modification of compressed air pipeline for the system staggered gas and pulse dust removal system is proposed and implemented, which not only solves the conflict and disharmony in the process of production gas, but also achieves the purpose of saving energy.

The specification of compressed air system, the basic requirements of pipeline design and installation; A design example of a 49,000DWT bulk carrier's compressed air system is presented. Combined with the typical technical problems in the design of previous real ships, the paper gives a specific solution through theoretical analysis and experience summary

By analyzing the principle and formula of gas flowmeter, the influence factors of measuring accuracy are given. The flowmeter selection of compressed air pressure reducing valve pipeline of a certain diesel engine is studied by using the flowmeter selection flowmeter flowmeter flowmeter.
