Pipeline size calculation
Thread Content
Knowing the material, pressure, and flow rate, how do you calculate the pipe size? Could someone experienced give me some advice?
Knowing the pressure allows one to determine the appropriate wall thickness for the pipe (different wall thicknesses result in significant price differences). Knowing the flow rate makes it possible to calculate the nominal diameter of the pipe.
You need to calculate the volumetric flow rate: Vs=3.14*D2/4 (Chapter 1 of Chemical Engineering Principles: Fluid Flow)
First, calculate the inner diameter of the pipe based on the flow rate and velocity requirements, and then select the standard pipe size from common pipe materials； Based on the pipe diameter and pressure, as well as the material parameters of the pipe (such as allowable stress), the wall thickness is calculated; together with the corrosion allowance, this determines the required pipe material. Calculations can be carried out with reference to GB150 \"Steel Pressure Vessels\" and the \"Code for Design of Industrial Metal Piping\" (it seems to be GB50160)
Reply to 5# hate3262: It mainly depends on the flow rate of the fluid. You already have all the necessary conditions; what’s missing is just the flow rate. The flow speed of the liquid is generally set at 1 meter per second.
