Pipe Racks in Process Plants

They provide support to both the supply and return pipelines. By providing adequate support, they will keep pipe flexing within acceptable limits. They also help dampen vibration from the pipes that may have an adverse effect on some delicate processes.

Good answer.

In addition they form a trunk route for services in the same way the spine does for the central nervous system in mammals.

It could be where they hang their pots, store their Bikes, or hang their clothes,

But sometimes they just store pipes

This sounds like a stupid academic question which someone has made out of a text book.

Sorry.....the only place you will find the correct answer, will be in your text book.

The main "important of the pipe rack in the process plants" is that it supports pipes...it prevents pipes from falling down. Why is that important? Well, it is important because, if the pipes fall down, the process is interrupted and if the pipes are not put back up again, the process stops. In other words, if the process is important, then the process pipes must be adequately supported.

Hope that helps.
