What safety measures should be taken after the safety valve is removed and verified?
Thread Content
The safety valve of a fractionating tower in our gas separation unit was removed and calibrated, but there was no backup safety valve to replace it. It is now working without a safety valve (about 15 days). Since there is no safety valve, the device requires a document such as safety measures and plans. Can anyone provide a similar document? Many thanks.
It seems that there is no such document. In the industrial field, you cannot make big mistakes. It is more reliable to prepare a replacement.
This is a relatively typical violation, please discuss it in depth: handshake
This is illegal. In fact, you only need to know the design pressure of the equipment, and then stipulate that workers can only control it within the range. It's not a big problem if there is no safety valve, that's the truth. Making a plan is stupid. It will be very troublesome to solve problems when they arise, and you will be criticized everywhere.
If the safety valve installed during the production process expires, you can submit a report to the local work safety supervision bureau for deferred verification, and it is not illegal to inspect it during the shutdown and get approval. To deal with the above situation, management and technical personnel of processes, equipment, production, etc. must hold meetings to formulate operating parameters and operating precautions for extraordinary periods, and jointly make emergency response plans for abnormal process parameters. We can't just focus on production and ignore safety. In the future, we will directly deny violations from the safety gate, and there will be no need to make a contingency plan. Personal opinion.
This situation does exist. The so-called plan is actually to strengthen the process control without safety valve.
Reply 5# It seems that the Dark Green Dashan safety valve is not under the supervision of the Work Safety Supervision Bureau, right? :lol You should apply to the Quality Supervision Bureau. It is best to check this kind of thing during the maintenance that is about to expire. It doesn’t matter a month in advance! Or apply for an extension!
Reply 7# You need double valves for AC vs. AC, according to* * Relevant laws and regulations stipulate that whoever makes this plan will "get in"
I would like to ask the poster why he didn't buy a new safety valve before it expires and it works well for later use. This behavior of the poster's unit is a serious violation of laws and regulations and poses a great safety hazard. It is recommended that the poster does not dismantle the old calibration first, but buys a new one and has calibrated it before dismantling the old one.

Even starting a plan cannot remedy the situation. The plan can only reduce accident losses. There are only two options, stop or replace the safety valve that has been calibrated. Don't lose the big for the small, not to mention the spare safety valve can be used again next time.
This is completely unacceptable. Because our company's waste heat boiler has been running for a long time, it cannot be stopped to disassemble and inspect the safety valve. In the past few years, people were asked to come to the site for adjustment. If it encounters major repairs, it is usually sent for inspection in time. Driving without a safety valve violates relevant regulations and is irresponsible for your own production safety.
