ceiling distance from the top of pipeline
ceiling distance from the top of pipeline
(OP)
Hi Everybody,
Just want to confirm if there is minimum distance requirement between ceiling and the top of pipeline?
My pipeline is an cooling oil pipeline suspended from ceiling with 3.5" diameter.
Another question is what kinds of pipe material normally can be used for this kind of pipe? My oil is TERESSO 46.
thank you very much for your attention!!

RE: ceiling distance from the top of pipeline
Seems like 300 mm (12"+/-) would be good for a minimum clearance to anything, but ... depends on a number of things.... and it still might be hard to inspect in difficult areas.
Pipe material primarily depends on operating pressure, temperature, chemical compatibility, anticorrosion properties, external loadings, cost... just to name a few things... and I have no idea what that oil is, or what comes along with it.
Any other details you don't want to mention?

Sorry for forgetting to mension those data!
The operating pressure will be about 50 psi, the temperature is about 50 degree C. there is no external load since the pipe is within house. Cost if not very expensive and normal price will be ok. Anticorrosion should not be problem since that pipe is only used for oil, a little extra thickness for anticorrosion should be enough I think.
As for availability, deliveribility and constructability, I prefer some pipe material which is quite common and easy available and quite often to be used during contruction will be better.
As for the Teresso 46 oil, the following link gives some information about this oil.

I am still searching the properties about this oil.
thanks very much for your reply!

If you had some money and were concerned over contanination AND the risk of fire in the building was low AND there was a sprinkler system, I'd look into an Aluminum alloy line.
RE: ceiling distance from the top of pipeline
Appreciate your information! I thought to use ASTM A106 GRADE A. therefore, our thinking is quite similar to each other!
thank you very much!

Therefore From any obstruction to the centerline of the pipe should be a minimum of
(Flange Radius + Insulation Requirements + 1")

RE: ceiling distance from the top of pipeline
Since the temperature is only about 50 C. I am not thinking to sue insulation.
I am thinking to pipe hanger. It is only a single pipeline. the problem is that there are many pipelines there already. It is very hard for me to find a good space for this header to keep straight. I am expecting that there will be many elbows for this header. I know that is not so good. But if I put it as straight as I can, I will have to put it very low. Too low maybe not so good. I am not sure if there is some rules which will limit my lowest height.
I do not want it to be too low, therefore, I am trying to use lots of elbows to pass lots of obstructions. So that I can still hang this pipe very close to the ceiling.
Appreciate everybody's reply and help!
Hello2006
Sorry! what is flat-turn?
The reason that I do not like to keep the pipeline too low is that it looks not good and too obvious compared with so many other pipings already there and all of them are above the trapeze and close to the ceiling.
all those pipes are above light too. If I put this new pipe lower, it will below the light which looks not good too. And also it will be at the height of the top of the door. I can keep the pipe far enough from the door, so that door can still be open. But it will looks bad I am thinking.
