Discussion on on-site leak sealing issues
Thread Content
In a production system, raw materials need to be pumped into a reactor for reaction; these raw materials are toxic. A polymerization reaction takes place inside the reactor, and the supply of these reactants must not be interrupted. Since there is no backup pump installed for the pumping unit, a leak occurs in the outlet pipe of the pump. How should this situation be handled? My recommendation: 1. During the transportation of the pump, carry out emergency leak sealing; wait until polymerization is complete before proceeding with thorough leak sealing ； 2. Cut off the source of the leak; while locating the point of leakage, continue the polymerization reaction by manual feeding, but safety measures may not be in place, making it quite dangerous. Thank you all for your suggestions; thanks
Urgent leak sealing~ Once that’s done, it’s best to promptly order a spare pump
If possible, punch the time first through a pipeline, and handle it after stopping any leaks or other issues.
Consider the properties of your material, as well as the pressure and temperature involved in pipeline transportation; determine whether quick-drying adhesives can be used for emergency treatment, or whether rapidly setting cement can be employed for temporary fixes.
Temporary solution: Before polymerization is completed, install a sealed jacket with a collection tank at the leakage site. The collected leaked liquid is recovered and fed back into the raw material tank. Wait until the polymerization is complete before carrying out the leak sealing.
There are professional tools for sealing leaks, such as pipe clamps, but what I really want to say is that the design of your factory is extremely unreasonable. Normal factories have several levels of contingency plans; it’s better not to work in a factory like this
This requires formulating an appropriate leak-sealing plan based on the outlet pressure of the pump. 1. If the medium temperature is below 60 degrees, it is easier for humans to operate, and plugging leaks under pressure is possible. If it’s possible to explain the properties of the medium upstairs, there will be a way.
It depends on the properties of your material, as well as the pressure and temperature during pipeline transportation; if possible, it can be tightened using pipe clamps first. After adding the material, check the wall thickness of the pipe.
Safety in chemical production is of top priority; considering the toxicity of the materials, the amount of leakage, and the high pressure at the pump outlets, it is recommended to shut down the operation for handling.
As a toxic substance, decisions must be made based on pressure, temperature, the amount of leakage, or the degree of controllability. Generally, the amount of leakage is not large; with appropriate protective measures, it does not pose a threat to safety. Emergency sealing methods can be used, such as installing clamps or applying sealant ； If the leakage is severe and poses a threat to personal safety, it is necessary to shut down operations for handling.
Leaks should be sealed under pressure urgently, and there must be a backup pump
Thank you all. The emergency handling in production was due to a lack of prior prevention; this situation arose because there were no backup pumps and the design was not adequate enough. The outlet pressure of the pump is 4-6 kg, and the temperature is 70-80 degrees. I will take everyone’s suggestions into account to develop a specific implementation plan
