I hope everyone will discuss actively before checking them – on which pipes should safety relief devices be installed? The answers are below. I hope everyone will engage in active discussions before checking the answers. The hidden content in this post can only be viewed by replying. Answer: A safety relief device should be installed in cases where one of the following conditions applies: (1) Equipment and piping systems whose design pressure is lower than the pressure at the external pressure source, and whose outlets may be closed or blocked ； (2) Outlet pipes of positive-displacement pumps and compressors whose outlets may be shut off ； (3) The vapor pipeline at the top of the distillation tower due to overpressure caused by a disruption in the cooling water or return flow, or excessive heat input to the reboiler ； (4) Equipment and pipeline systems subjected to overpressure due to the accumulation of non-condensable gases ； (5) The pipeline upstream of the shut-off valve or control valve in the outlet pipeline of the heating furnace ； (6) Pipeline systems that experience thermal expansion or vaporization due to the closure of the end cut-off valves, influenced by ambient temperature, solar radiation, or heat tracing ； (7) Pipeline system upstream of the reactor outlet shut-off valve in cases where exothermic reactions may get out of control ； (8) Steam outlet pipe of condensing steam turbine ； (9) Outlet pipes of steam-generating equipment such as steam generators ； (10) Outlet pipe of container for low-boiling-point liquids (liquefied hydrocarbons, etc.) ； (11) Outlet pipe on the low-pressure side of the heat exchanger, which may experience tube rupture ； (12) Other areas where the design suggests that overpressure may occur.
Ultra-high pressure pipelines, high-pressure compressed gas pipelines,
Safety valves must be installed on the steam pipes.
Safety valve, breathing method, rupture disc,
Ultra-high pressure pipelines, high-pressure compressed gas pipelines； Steam pipeline ； Toxic gas pressure pipeline ； Combustible gas pressure pipelines.
Safety relief devices should be installed on the upper part of the pipes following the heat exchangers; safety valves should also be provided for storage tanks and tower equipment
Reply to 1# feng_200108047: Safety relief devices must be installed on the pipes of pressure vessels; the primary purpose of these safety relief devices is to protect the vessel.
Safety relief devices must be installed on the pipes of pressure vessels. The primary purpose of these safety relief devices is to protect the equipment and pipelines, especially in cases involving gases that are prone to vaporization or compressed gases
Reply 1# feng_200108047: 1. The outlet pipelines of plunger pumps and positive displacement pumps. 2. The medium in the pipelines is clean. 3 The process requires pipelines with stable pressure.
Steam pipes, vaporizer relief devices
