Title: a lesson in pipe?????
Post by: tbone on June 03, 2008, 01:25:29 PM
firstly, i no, we covered all this before! but having seen andy mention `pipe center` in his frame build thread, i thought i`d check them out. They are a franchise and have branches nationwide.
The web site is slow and hard to use, unless you know your Part no`s. I was also advised not to order from the web site, but contact my local branch directly as in most cases they could offer a better price!
This is not an indorsment of thier products, but a guide to thier pipe sizes.
Pipes are identified by "nominal" or "trade" names that are loosely related to the actual dimensions. For instance, a 2-inch steel pipe has an inside diameter of about 2 1/8 inches and an outside diameter of about 2 5/8 inches.

It is common to identify pipes by inches using NPS or "Nominal Pipe Size". The metric equivalent is called DN or "diametre nominel". The metric designations conform to International Standards Organization (ISO) usage and apply to all plumbing, natural gas, heating oil, and miscellaneous piping used in buildings.

Diameter Nominal         nominal Pipe Size
   
 - DN -                        - NPS -
   (mm)                      (inches)
6                               1/8
8                               1/4
10                             3/8
15                             1/2
20                             3/4
25                             1
32                             1 1/4
40                             1 1/2
50                             2

L11024            50mm          60.3mm               M of red med p/e tube en10255 50mm

L11041            25mm          33.7mm               M of red hvy p/e tube en10255 25mm
L11042            32mm          42.4mm               M of red hvy p/e tube en10255 32mm

L11044            50mm          60.3mm               M of red hvy p/e tube en10255 50mm

Medium (med) pipe has a wall thickness of 3.2mm
Heavy (hvy) pipe has a wall thickness of   4.5mm
The OD remains constant between med and hvy, so the ID will not be as stated, it is a nominal size.
Minimum qty of sale is 6.5 meters although its priced per meter.
EN10255 is the red coated stuff that has now replaced BS1387
P/E = Plain Ended
S/S = Screw Section:  one end male threaded, one end female threaded
E/E = ????? (was mentioned on web site but no one i spoke to knew wot it meant)
And if you ask nicely, sometimes they will cut it up to managable lengths for free!
Information sourced from the web site and a very nice lass in bristol so if its wrong, blame them.

   E/E would normally be end to end and is used to define the length that a pipe needs to be cut to, to fit between fittings. The fittings are shown on drawings as being C/C (centre to centre) so the distance from centre to mating face has to be deducted to arrive at pipe length, sometimes an additional allowance has to be added back on to allow for threading, occasionally this is not added and the cussing begins, much to the merriment of the carpenters who pride themselves on their abilities with tape and rule.

Brock's one of those annoyingly talented people who can work just as easily in wood as metal. He served an apprenticeship as an engineer before switching trades to take up carpentry & joinery, (what's the difference?). He can make stuff fit without bashing it wiv a 'ammer, so is officially a clever git.
Thanks for the info TBone. Appreciate the research.  ;)

"Thanks for the info TBone. Appreciate the research.  "

Brock's my big brother. Unfortunately the cleverness doesn't run in the family. I'll have to settle for being the cute one.  :P

Come on Andy you know what that one is:
Carpenter lays Carpents
Joiner joins stuff together :)

My old man was a carpenter, cabinetmaker and wheelright by trade. I always think of anythink to do with wood as being carpentry, good job my old chap aint around to see me type it though eh? ;)

I always wanted to be a cabinet maker.  The diffrence really is a bit like the difference between a house-painter and a painter of pictures!

Carpenter does things like rafters and doors and windows - a cabinet maker makes fine furniture.

Nearest I ever came was building a sledge for my children with skills my dad taught me.  Must have done it right cos my grandchildren use it now - isn't that great?   :D

I don`t get on with wood very well, measure 5, 10, 15 times and I`ll still cut it wrong. If it doesn`t melt when you put a flame to it, I have no idea what to do with it. :D :D :D :D
