Installation of safety valves on the heat exchangers in distribution stations

2009-04-13View Original

Thread Content

I found that some heat exchangers at natural gas distribution stations are not equipped with safety valves; these heat exchangers are installed in high-pressure sections (around 5.0 MPa), while safety valves are only installed on the hot water boiler’s outlet pipe (located inside the boiler room), where the pressure is lower, at 0.6 MPa. If gas penetrates the pipes over time and causes natural gas to escape into the boiler room, isn’t this dangerous? Is such a design in compliance with **regulations and standards**?
