Documentation of process pipelines

I’ve never heard that process pipelines need to be documented. If it’s necessary, a PID diagram is usually drawn; in addition, including a pipeline layout diagram would be sufficient

It is not possible to document all process pipelines; the main ones should be drawn as single-line diagrams, with pipeline numbers indicated according to the design drawings.

It is necessary to create records, and it’s quite simple: just do so according to the process pipeline numbers

Process pipelines should be classified first, with separate records kept for different categories of pipelines； Pay special attention to high-temperature, high-pressure pipelines as well as low-temperature pipelines!

Below is the relevant information on document preparation for process pipelines: http://bbs.hcbbs.com/viewthread.php?tid=319740&page=1#pid1811701

It is recommended to follow the safety management methods for pressure pipelines when establishing records and managing process pipelines: 1. Based on the list of process pipelines in design documents such as process piping construction drawings, prepare a corresponding list of process pipelines (or a statistical record of process pipelines)； The format and content of the checklist can be referred to Annex 2, \"Summary Table for the Registration of Pressure Pipeline Use,\" of the General Administration’s Document No. 213 of 2003, \"Rules for the Management of Registration of Pressure Pipeline Use.\" 2. Draw the corresponding pipeline single-line diagram based on the list, paying attention to the one-to-one correspondence. 3. For the single-line diagram of each pipeline, create a pipeline record ； Specifically record matters such as operation, inspection, testing, repair, modification, and changes to enable classified management.
