Problems with expansion bends in steam pipes

This needs to be calculated – the mass flow rate, to see if it’s sufficient

Could you elaborate on the specifics regarding expansion bends? Thank you. I need to determine the height of the pipe rack based on the vertical height of the expansion bend (going downward)

Calculate the temperature drop along a 3000-m pipeline based on the requirement of 16 t/h of steam at the end point (in terms of pressure and temperature), and then determine the amount, temperature, and pressure of the steam at the starting point. (The temperature drop calculation can refer to the adiabatic insulation calculation.) ； 2. Calculate the pressure drop for a 3000m pipeline, and then determine the size of the pipeline. Since steam is a compressible fluid, it is recommended that you use the calculation methods specified in \"HG/T 20570.7-95 Calculation of Pipeline Pressure Drop\" under the category of single-phase flow (compressible fluids) to determine the pipe diameter. 2. The layout of 3000m pipelines cannot be in a straight line; therefore, the dimensions and spacing of expansion bends must be determined through stress calculations based on the direction of the pipeline layout as well as other factors such as pipe wall thickness, type of pipe support (concrete or steel), insulation layer, and properties of the fluid flowing through the pipes. For flexible computing, it is recommended that you follow the provisions of the \"SH/T 3041-2002 Code for Flexible Design of Petrochemical Piping\", and use CAESARⅡ or AUTOPIPE for calculations for your reference
