During design, which discipline is responsible for pipeline design?
Thread Content
Our company has a small staff, and those with expertise in engineering are responsible for pipeline design. However, no one learned this stuff during school – things like material selection, determining pressure levels, arranging pipe supports, and thermal compensation. I wonder if there is a specialized field for pipeline design. If I want to learn this on my own, where should I start?
I don’t know what pipeline design you’re talking about There is information on pipeline layout in chemical engineering drawing! The pressure should be calculated using the formula for containers in GB150! Select the materials according to GB150 by yourself! The pipe rack can also be determined by yourself! As long as it makes sense, that’s fine! I haven’t come across thermal compensation yet, so I don’t know, haha!
It’s the piping specialty; there’s a dedicated department for this in design institutes!
In some facilities, process engineering and piping are not separated; it’s all part of pipeline work. Nowadays, in many facilities, process engineering and piping are separated. As mentioned by LZ, apart from pressure being definitely part of the process work, material selection, pipe rack layout, and thermal compensation can all be considered part of piping work. If the specialties are divided more finely, material selection falls under the materials science specialty, thermal compensation is part of the stress engineering specialty, while pipe rack selection still belongs to piping. However, I’ve heard that some foreign engineering companies have specialized teams for selecting pipe racks. As for how to get started with piping, many newcomers ask about it. From my experience, it’s still necessary to get involved in projects and work diligently on a project under the guidance of an experienced person; that way, one will become familiar with the basic workflow. Look at more diagrams, ask more questions, take the opportunity to visit the site in person, summarize the mistakes made, and accumulate knowledge from other fields. In short, try to learn about and engage with everything related to your work; there are only advantages, no disadvantages.
The piping specialty includes several sub-specialties such as piping layout, piping machinery, and piping materials.
This can be started with just basic knowledge; design it step by step in accordance with relevant standards such as the GB150 Power Piping Design Manual.
Reply to 5# zguangshu110: There is also pipeline stress analysis
Reply 8# iaft: Wrong; pipeline stress analysis falls under pipeline mechanics
In accordance with design procedures aligned with international standards and professional specialization: the process engineering field is divided into the following specialties: process engineering, process systems, process piping, equipment layout, piping materials, piping machinery, heat exchanger analysis, and pumps (or dynamic equipment) engineering. Currently, each design institute determines the division of labor for process-related tasks based on its size and staff composition. In some cases, due to personnel being under control, no distinction is made at all, and the process engineering department handles everything (in other words, all the tasks mentioned above are carried out by the process engineering department). The unit for LZ is probably something like the case mentioned later.
Reply to 8# zguangshu110: Well, that’s right; actually, both materials and stress analysis can be included in pipeline machinery
A plant is generally structured as follows: the piping room is where the piping layout is planned, as well as where material control is carried out (regarding stress, material selection, corrosion and insulation protection, etc.); external pipelines may also include thermal pipelines.
