A parameter issue in ASPEN simulations of steam pipelines
Thread Content
I want to estimate the overall heat loss of the pipeline while also calculating the pressure drop in it. But I don’t know what a suitable value to use for the heat transfer coefficient of ordinary steam pipelines is It’s just an estimate. I want to design a steam pipeline with a pressure of 2.0 MPaG, a diameter of DN600, and a length of 2 km (including the equivalent length of compensators, etc.). Specifically: In the Thermal Specification section of BLOCKS in PIPE, there is a Heat transfer coefficient that needs to be filled in. The unit is Walt/sqm.K; I’ve seen some people use 3.5 while others use 20. If insulation is done well, how low can it go?
