Pipe size range in a chemical plant/ refinery 3

[alkorm]

Hi everyone! I am looking for statistics, on what are the typical pipe size ranges are in the chemical plant and/or refinery. I am particularly interested what is the percentage of 6 to 27 inches pipelines (or else +/- 5 inches) in a typical chemical plant or refinery?

There's likely no such statistics and it will vary wildly on the plant/process. I doubt there's any valuable data to be gleaned.

In my general industrial experience (chemical, pulp/paper, power), the vast majority of our piping is 6" and below, with a fair amount of 8-14", and above that drops off fairly quickly.

On the other hand, at fuel depots and similar type locations, 10" pipes are laughed at for being so small.

RVAmeche, if you were to estimate the pipes presence, can you say that 6'' is 80%, 8-144 '' - 15% and others are the rest, 5%?

Good luck as the data you are looking for almost certainly doesn't exist, if for no other reason than the range of sizes of a "chemical plant or refinery".

Also what do mean by percent?

Length?
Mass?
Number of regardless of length?

So right there you can get three wildly different answers to your question.

give us an idea why you want to know and you might get somewhere....

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

If you are working in such a planr, visit the warehouse and get details of piping ordered in rhe last 5 years.
This data should exclude all piping ordered for new projects.
Now you can arrive at some statistics.
Talk to operation and find out the piping size with estimated length they have in their plants.
Fine tune the above statistics to inch towards the actual. Do remember, this data is specific to your plant and cannot be generalized.

I am looking for statistics, on what are the typical pipe size ranges are in the chemical plant and/or refinery.

There are too many variables to have a meaningful answer for the request which may start with what's the "typical" plant in terms of the product type, process capacity & conditions, etc. I think that a project management company may collect enough data from various plants and can provide a good statistic result for the reference. Good luck.
