Determination of saturated steam pipelines
Thread Content
We now need to select the diameter of the steam pipeline: the steam pressure is 0.8 Mpa (absolute), and the flow rate is 20 t/h. What diameter would be appropriate?
When selecting the diameter of steam pipes, factors such as pressure loss, flow rate, and energy efficiency need to be considered. For an absolute pressure of 0.8 Mpa and a flow rate of 20 t/h, it is generally recommended to use pipes with a DN150 diameter (150 mm). This ensures lower pressure loss and an appropriate flow rate, while also facilitating the installation and maintenance of the system. If more stringent control requirements are imposed on pressure loss, considering the use of DN200 (200 mm in diameter) can help reduce pressure loss. It is recommended to conduct a detailed calculation or consult a professional to determine the most suitable pipe diameter. .
The calculated inner diameter is around 260, so it is recommended to use a DN300 pipe
