I have a question regarding piping technology
Thread Content
Dear experts: I specialize in piping technology, and now I want to pursue a career in pipe materials. I hope you will kindly share your insights regarding the work processes involved in this field, as well as the standards and selection criteria that are commonly used. Thank you!
Study the PMS (piping material specification) for each project more closely
GB/T20801-2006 \"Code for pressure pipelines – Industrial pipelines\", especially the material section; let’s study it first
The most important task regarding pipes is to determine their pipe grade; it’s necessary to examine the pipe grades for various projects and then consider the relevant standards
Who can explain in detail the process of selecting materials?
The material grade is just one of the documents prepared by the piping specialty; depending on the role of the organization in the project and the stage of the project, the focus of work for the piping specialty also varies
I studied Materials Science and Engineering in university, and since graduating I have been working on design related to pipeline materials (as well as database management), for almost 8 years now. I really love my job. I’d like to share some of my experiences, as a way to stimulate discussion among fellow netizens, in the hope that it can be helpful to you. 1. Regarding the workflow: 1) Understand information about the project in question – whether it is a new project, a renovation, maintenance work, or some other type. 2) Project implementation timeline and schedule. 3) Are there any unified regulations? 4) Accept conditions such as PFD, PID, piping diagrams, and unified specifications. 5) Analyze the above conditions and search for relevant information. 6) Prepare the initial version of the grade chart, valve specification sheet, etc. 7) Update the document as the project progresses, and submit it for proofreading and review until the final version is ready. 2. Regarding information: An important aspect of design work is learning how to find relevant information – either through data support or based on practical experience from field use. Even if neither of these is available, a risk assessment must still be conducted to minimize risks. After all, when it comes to design, safety comes first. Remember not to make decisions on a whim; this is not a good habit, and it will eventually lead to serious problems. Level and reliability of information: 1) Laws and regulations ； 2) **and departmental standards ； 3) Industry standards ； 4) Enterprise standards ； 5) Contract ； 6) Other materials ； 3. Some recommended materials: In addition to the commonly used standards, I recommend that you consult some classic references: 1) Guidelines for the Implementation of GB/T20801 (edited by Ying Daoyan); 2) Pressure Pipeline Technology (edited by Yue Jincai); 3) Corrosion Data and Material Selection Manual (edited by Zuo Jingyi); 4) Corrosion and Protection Manual (published by the Chemical Industry Press); 5) Series on Analysis of Advanced Foreign Valve Standards (edited by Lu Peiwen); 6) Guide to the Selection of Industrial Valves (published by the Chemical Industry Press); 7) ASM Handbook (a very good set of resources). Additionally, it is advisable to read more materials from ASTM, ASME, API, NACE, as well as from foreign industry experts. 4. Some other suggestions: Theory should be combined with practice. Take the opportunity to visit sites more often, go to manufacturing plants, communicate with peers, and seek advice from experienced workers – this way you will make rapid progress!
