Design of the temperature and pressure reduction system
Thread Content
For several pieces of equipment in the drying stage of a new project at our company, 0.4 MPa of low-pressure steam is required, whereas the steam available from the external supply system has a pressure of 1.0 MPa. It is therefore necessary to design a steam temperature and pressure reduction system; how should this be done? Newbie seeking advice
The simplest way is to install a pressure relief valve； For precise and reliable performance, install an automatically controlled pressure regulating valve.
Design a pressure reducing valve; if flow control is also required, install a control valve after the pressure reducing valve. The temperature and pressure of saturated steam are related to each other, and a decrease in temperature goes hand in hand with a decrease in pressure
As a reminder, the said steam pipes are considered pressure pipes, and relevant qualifications are required for their design and construction. Furthermore, if a pressure reducing valve is installed, a safety valve should be installed downstream of it to prevent equipment safety issues caused by overpressure.
Thank you all! I roughly understand what it means. Now the manager says that since there are many pipelines that need to have their temperature and pressure reduced, he just asks the design institute to carry out the design work
