Static grounding of steam pipes
Thread Content
According to the regulations of some design institutes, low-pressure steam pipelines are also required to be electrically grounded. What is the reason for this? Please give me some advice! Thank you!
He needs to take it; you can require his standards, but not his own – rather, national standards, industry standards, or standards set by the sector.
Design institutes generally require that all metal pipes be statically grounded; the accumulation of charge is not only unsafe for the pipes themselves, but it also poses a safety risk to surrounding flammable and explosive piping systems
A higher flow rate of the medium makes friction more likely to cause changes in charge, so it is normal to require grounding
Steam pipes often contain rust particles, among which ferric tetraoxide is prone to being magnetized by the surrounding environment (such as the earth’s magnetic field), thereby magnetizing the pipes； On the other hand, the rapid turbulent flow of steam inside the pipeline tends to generate vortices, and vortices can give rise to magnetism ； High-speed flow of the medium and friction with the pipe wall generate static electricity.
Has it passed through the explosion-proof area? Everything needs to be done inside the explosion-proof area. If it is not an explosion-proof area, follow the design. Generally, low voltage is not required.
