I have questions regarding Elbow Pipe System. Is there any Lubrication system in Elbow pipes ? can anyone give me details about Elbow pipes?
Thankyou in advance

Hi Every one !!

Why? Are you a pipe fitter?
The question is far too generalised.
Ceramic?
Steel?
Copper?
Aluminium?
PVC?
If you were genuinely interested 1, i.e. you need an elbow (and, for reference they're not called "elbow pipes", just "elbows" 2) for a job, then you can (more often than not) download the relevant catalogues with specs from suppliers or manufacturers.
1 I suspect you're not: what would be the point of lubricating an item designed and intended to carry liquids? How much "lubrication" do you think they'd need? And how would you prevent that "lubrication" from contaminating whatever's being transported?
2 Simply because it's not a pipe until it's a system.
Ahem, that would be elbow grease, and you are expected to supply it yourself.Originally Posted by sinika

nop i m not..
thanks .. i just want to ask a general question regarding elbow pipes as i am a student and i have to research about lubrication, surface properities and other properities in elbows pipe but i couldnot find . As, in long straight pipes we can introduce lubricating fluid so that it provides a uniform thin film that separates viscous and sticky materials from the inner wall of the pipeline and effectively lowers the pipeline friction loss. Can we introduce such lubricating fluid in area of Elbows?
<br><br><br><br>yes but we can greasse in outer part but what about inner part during gas flow in a sytem<br><br><br>

I'll repeat myself.
Your query about "surface properties and other properties" largely is meaningless unless you specify the material used for the elbow.
You're going to have to provide a specific reference for this because the only use of lubricants in piping that I'm aware of is for either easing the assembly of joints (in which case that lubricant is removed as much as possible after the joint is made) or on the outside of drill piping (to reduce friction while drilling).As, in long straight pipes we can introduce lubricating fluid so that it provides a uniform thin film that separates viscous and sticky materials from the inner wall of the pipeline and effectively lowers the pipeline friction loss.
Like I said, any interior lubricant would cause contamination problems with whatever is being transported by the pipe.
Those problems would vary from time-consuming and medium-expensive (relatively trivial) to actually dangerous/ potentially lethal (and thus relatively less trivial).
Edit: after considerable Googling (with various parameters) I found this and this.
The short answer, then, would be: it depends.
On rather too many factors.
What's the planned flow rate?
What liquids are being transported?
Will that lubrication maintain its contact with the inside of the elbow? That's got to be dependant on radius/ viscosity/ flow rate/ etc.
I'd suggest your best bet is to get in touch with someone at either of those links (probably the one that's actually selling a product) and talk to them.
They may be able to point you in the right direction even if they can't give you answers. If you're really lucky (and they don't have the answers) they might even be interested in employing you to continue that work (if that's where you're going with the project).
wrong on my part

Thankyou very much
I don't think you would want to mix the gas you are delivering with any potential contaminants as it could cause trouble at the receiving end. Less joints mean less friction. Avoid socket fittings and use more butt fusion if plastic. Don't use threaded fittings for metal, weld. If you are reducing then use a tapered weld elbow instead of joints. I know some engineers at the local natural gas utility, I'll ask them your question if I remember to.

Thankyou for your answer.. Yes i will be glad if u will ask them and help me out

Why have you not been able to find this information on google?
