1. To connect same size, kind and type of pipes.
Types of Fittings used:
Union-used at connections which may have to be opened without disassembling any of the piping or other fittings
Coupling- has internal thread at both ends so thatt they may connect together towo pipes and to end
2. Used to connect two different sizes of pipes
Types of Fittings used:
Reducer/Increaser
Bushing
3. To change the direction of the flow of water
Types of Fittings used
Elbow/Bends-used in both G.I. pipe ad PVC pipe
Tee- used by all pipes
-used if there is chande in two direction
Cross-usually used in drainage system
- used if there is a change of flow in three direction
Wye- also known as Crow Foot. Used for cast-iron pipe
4. Used to stop the flow of water
Types of Fittings used:
Cap-has internal thread
Plug- has external thread

Having watched countless Hollywood movies, 97 times our of 100, I can understand American English without the need for a translator. This article, however, assuming it is well written in American English, is confusing.
In England a pipe implies conveyance of a fluid while a tube is a geometrical structure (hence water pipe and scaffold tube). Having edited the openining paragraph on this basis, I have noticed that' scaffold pipe' makes sense in American English. I am itching to edit more sense into this article but I have (only) a vague awareness of Wiki policy re this matter.

"The most commonly used schedules today are 40, 80, and 160. The schedule number is an approximate indicator of the service pressure that the pipe can take. To convert schedule number to pressure, divide the schedule by 1000 and multiply by the allowable stress of the material. The result will be in the same units as the stress value."
I'm not really surprised to hear that the NPS standard is messed up by a factor of 4, or that PVC standards are substantially different. It's a complicated standard with lots of legacy features, and I'm sure I don't even know half of it. This article is still far from a stable polished version, so you should feel perfectly free to insert whatever you know about the topic. I have no experience with PVC pipe, and your help is appreciated.-- Yannick 06:29, 5 February 2006 (UTC)
Both this article and Tubing (material) state "The terms 'pipe' and 'tubing' are interchangeable." I propose that they both be merged into one article - either this or Tubing or maybe a new one called, e.g., 'Pipe and Tubing'.

Pipe and tubing are almost interchangable, as now stated in 'tubing'. Also, some tubing is square, rectangular and so on. You would be hard pressed to find a square pipe.

I was trying to find an article on Polybutylene pipes, which leak after a number of years. There was a class action law suit against the company(s) that manufactured them. I think an article on this is important. I dont know how to make an article though...is anyone else up for it?
I found the acronym OCTG listed on a description of a manufacturer. I'm not sure if it would be worth mentioning here. -Crunchy Numbers ( talk) 16:14, 9 June 2009 (UTC)
The result of the proposal was not moved. Jafeluv ( talk) 07:07, 6 July 2009 (UTC)
I was looking for information on concrete pipes. Specifically I was looking for information on the technical details of construction, concrete mixes, spinning techniques, evolution, maximum theoretical dimensions, current usages, manufacturers, etc. From even this partial list it is clear that putting all informtion on "pipes" into one article is absurd. The article, should it hope to become encyclopaedic, would become far too big. At present it is of acceptable wiki size only because it is no more than an arbitrary hotchpotch of miscellaneous pieces of information.
As a "holding" page to reference other articles it MAY be useful, but this function is already catered for by the basic serach functionality.
To redirect and attempt to assimilate all information on "pipes" into one article seems to me to be entirely counterproductive. If wiki were to follow such a strategy logically and blindly then it would end up as one vast article covering everything from Aachen to Zygote, with every part hyperlinked to every other part. At that point some bright spark would say: "Hey, we could make it far easier to use this by turning each part into a separate article"!
o why don't we just cut out the middle bit and stop this valueless and purposeless mergeing of articles ... please. LookingGlass ( talk) 13:18, 23 November 2009 (UTC)
What are the actual OD, ID, and wall dimensions of common 0.5 to 2-inch black plastic "Poly Pipe" polyethylene tubing in the US? In other countries? - 96.237.78.13 ( talk) 00:48, 18 August 2010 (UTC)
Some mention of pressure in psi.-- 69.151.63.174 ( talk) 08:36, 22 August 2010 (UTC)
Some local handymen carry a coil of "hanger iron" aka "pipe strap" -- long, narrow ribbon of relatively soft steel sheet with a row of holes punched down the middle. One breaks off a desired length, wraps it around some loose object, and nails the ends down to wood framing to hold the loose object in position. Recently it appears to be used more around here than baling wire, but not quite as much as duct tape.
Alas, hanger iron and pipe strap are still redlinks to me -- Is there already an article on this material under some other name? Is it really an appropriate material for permanently hanging pipe? -- 68.0.124.33 ( talk) 04:33, 13 December 2010 (UTC)
An additional common method for manufacture of metal pipe is 'spiral wound' not mentioned in the article. 130.184.198.43 ( talk) 20:48, 11 September 2012 (UTC)
in the main article:
[...] In common usage the words pipe and tube are usually interchangeable, but in industry and engineering, the terms are uniquely defined. Depending on the applicable standard to which it is manufactured, pipe is generally specified by a nominal diameter with a constant outside diameter (OD) and a schedule that defines the thickness. Tube is most often specified by the OD and wall thickness, but may be specified by any two of OD, inside diameter (ID), and wall thickness. [...]
Pipe are identified by their nominal INSIDE diameter. It's the outside diam that vary depending of the schedule (wall thickness).
Tube are identified by their nominal OUTSIDE diameter. it's the inside diam/measure that vary depending of the thickness of the wall.
note: Schedule as thickness indicator is only use in piping. — Preceding unsigned comment added by PhilDesl ( talk • contribs) 02:46, 5 November 2012 (UTC)
Reference #2 mentions that the pipe was 330 yards long yet this article, referencing that source, says it was 380 meters. I'd fix this myself but someone would get angry. 50.81.18.120 ( talk) 19:22, 29 November 2023 (UTC)
