Handbook with Pipes Support Friction Factors, Steel on Fiberglass Reinforced? 1

[drakkkko]

Hello,

I Friction coefficient for Fiber Glass Reinforced Pipes.
Is there any Handbook which have those friction coefficient ?

Thanks in Advance!

If you mean GRP pipe with direct contact onto steel supports then this is not a recommended action. GRP wears badly when exposed to such impacts

If not please provide a bit more than one line.

Then it is usually called friction "factor". "Coefficient" is usually reserved for friction between two solids.

Well , thanks to Bimr about good intention and understand when I'm asking for references. But I have a mistake in the question written and I have caused a confusion that Big Inch mentioned above....sorry about that.
I'm asking references for data about friction between two solids , meaning "Coefficient".
I have to write document with reference that I use in flexibility modeling, i.e. "Handbook...."

As stated above, if you have friction between fibre glass / GRE and steel, after a fairly short period of time you won't have any fibreglass left... GRE really doesn't like abrasion, therefore I can't see the point in looking for this?? Care to elaborate?

LittleInch, thanks for your comments. I forgot to mention, that I have to write the Reports from Flexibility pipe analysis. I'm using Caesar ii , which ask for these Coefficient at every support...of course you can suppressed but I think is more realistic to use it. Anyway, I have to justify those "Coefficient"....but If there no...any reference at all...well I suppose I could try to argue what are you saying.

Have a look at this

You might need a different approach. Steel on steel is a much better idea IMHO.

That is the same guide as posted above.

Sorry, it looked different, page 7 onwards was what I was looking at. My point remains which us grp on steel where movement is expected is not a good idea
