Questions regarding the selection of compressed air pipelines
Thread Content
What is an appropriate inner diameter for a compressed air pipeline with a flow rate of 6000 m3/H and a pressure of 0.6 MPA?
According to Appendix A of SH/T3035-2007, for compressed gases with a pressure of 0.6~1.0 MPag and a flow rate range of 15~10 m/s, the pipe diameter can be estimated

The pipe length and the pressure requirements at the end uses also need to be taken into account to verify whether the selected pipe diameter is appropriate; flow rate is not the only factor to consider
1. The recommended flow rate ranges for media in different phases are based on keeping the total pressure drop in the pipeline within an acceptable range. 2. After selecting an initial flow rate, it is necessary to check that the pipeline pressure drop remains within the required values; if not, adjustments must be made until the requirements are met
