Precautions for putting instruments into use at various stages of new plant construction
Thread Content
After a new set of equipment is installed, the process pipelines must undergo processes such as purging, washing, and acid cleaning, as well as stages like water testing and heat testing. As for the instrumentation department, the installation and calibration of instruments generally begin only after the pipelines and equipment have been properly installed. For a newly installed set of equipment, from the initial stage until it starts operating properly, what aspects need to be taken into consideration regarding the installation, calibration, and commissioning of various instruments on site? For example, during the purging phase, it is necessary to remove the orifice plate to prevent it from being damaged, and so on... All experts are welcome to share their opinions and suggestions.
Remove the control valve; if not, have them use the bypass line, otherwise there will be numerous internal leaks once operation starts.

Just follow the operating procedures within your area of responsibility, as they are targeted. To avoid vague and unrealistic speculations. For example, the reason why the flow orifice plate needs to be removed during purging is not to avoid damaging its sharp edges, but because the presence of the orifice plate hinders purging and can also block the flow channels on the orifice plate flange. In fact, the key is to identify which processes are likely to cause damage to the instruments, and such processes should be prohibited. For example, the instrument pipes used during purging also need to be purged later; purging them earlier can lead to blockages. Instruments for special temperatures and analysis must be used within their specified range. Other regulations will be available. Unless one runs into counterfeit bandits, then the ability to act as an on-site supervisor is necessary. It’s not just a matter of paying attention to certain things; there’s too much content. These aspects are all part of the technical agreement in the contract. As the party responsible for executing the contract, it is necessary to refer to the agreed terms. For example, the relevant instructions are provided, and all the precautions regarding the correct usage methods as outlined in those instructions are included there. Read more and accumulate more knowledge – these are all key points to keep in mind. Read the instructions thoroughly, and your problem will be solved. I don’t recommend carrying a notebook around to ask others for \"tips\" – everything is already in the instructions. Why not give it a try?:)
We are a new project at a new factory, and everything is still in order. Do you have such a procedure? Could you send one? 920094990@qq.com, thank you
For new projects, it is necessary to collect information early, establish archives, and manage them. Everything you need is included in the equipment manual; each set of equipment comes with a packing document and relevant catalogs. Design a table and get started on managing it right away.
Please refer to the \"GB50093 Code for Construction and Quality Acceptance of Automatic Instrumentation Projects\"
Get the GB50093 specifications for the construction and quality acceptance of automated instrument projects. Thanks
The standards already exist; why go through the hassle?
