Knowing the flow rate in the main pipeline as well as the pressure and flow rate in the branch pipelines is important; it determines whether the piping selection is reasonable or not
Thread Content
I would like to ask an expert for advice: 1. The gas used is argon, supplied from ordinary 40L steel cylinders. The main pipeline runs through the corridor, with branch pipes leading to various rooms; there are 37 points where the gas is used. The flow rate at each of these branch points is 100 ML per minute, and the pressure is 0.5 MP. 2. There is a pressure regulator before the main pipeline, and the gas delivery pressure in the main pipeline can be set at up to 2 MP, with the possibility of adjustment. Pressure regulators are also installed at the end points where the gas is used. 3. May I ask if it is possible to use 1/4-inch (diameter 5.46 mm) stainless steel pipes for both the main pipes and branch pipes in my design? Is such a design reasonable? What are its drawbacks? What diameter should be used for the design?
Based on preliminary calculations, a flow rate corresponding to 1/4 of the pipe diameter can reach 136 liters per minute; therefore, the total flow rate should be more than sufficient to meet the actual gas consumption needs.
No problem; just consider the flow velocity within the pipe to be between 10 and 20 m/s
