Talk:Cured-in-place pipe

size

Does anyone know how big the CIPP industry is in the United States? — Preceding unsigned comment added by 70.61.45.147 (talk • contribs) 18:51, 19 August 2010‎

inversion

The word "inversion" here seems to have a special meaning in this article, but is not explained. It does not seem to mean to turn something upside down. Why would one do that? 71.189.115.144 (talk) 17:59, 12 May 2012 (UTC)[reply]

I agree - wiktionary:invert has a number of definitions but none of them quite make sense for how it's used in creating a cured-in-place pipe. --Marc Kupper|talk 22:10, 31 December 2012 (UTC)[reply]

I found a video on http://www.maxlinerusa.com/. It looks like their system is to insert a long bag (a sleeve, liner, or bladder) into the pipe under pressure and the way they feed the bag also means they are inverting it. I believe they invert it again to remove the bag.

http://www.easy-liner.com/lining_supplies/pipe/index.html is a page where they are selling what they call "Tube Pipe Lining Bladders" and on the detail pages for the products the processes or techniques described as Invert and Invert, Pull-in and Invert, and Double Inversion. The first two I can visualize. I'm not sure what "Double Inversion" other than perhaps a distinction between which end(s) they start the inversion from. --Marc Kupper|talk 23:02, 31 December 2012 (UTC)[reply]

Disadvantages

We need a better source but http://www.formadrain.com/frequently-asked-questions/ lists a couple of of disadvantages that are not covered by the current article.

The existing pipe needs to be clean. "anything that was there will stay trapped between the liner and the host pipe forever (ex: rocks, roots, grease)."
There's a four hour time limit from manufacturing a pipe to when you can start curing. The "pipe" is constructed in a shop, rolled up, transported to the job site, pulled through the pipe that's being re-lined, and then you can start curing the new pipe or pipe-liner. I assume other cured-in-place pipe technologies would have similar time limits.

Is "Cured-in-place pipe" also "pipelining?"

At present pipelining is for a computer term. It appears the term is also used for cured-in-place pipe.

This plumber's web page says they offer "pipelining" using products/systems from the following vendors:

CuraFlo - they do not seem to use the term 'cured in place' site:curaflo.com cured in place.

need to research www.curaflo.com to see if they call their product "Cured-in-place pipe"

Formadrain - many hits for site:formadrain.com cured in place.
Easyliner - www.easy-liner.com has many references to "CIPP" and a few for "Cured in Place Pipe Lining".
Maxliner says "Maxliner is a leading cured-in-place pipe (CIPP) lining system" and Google for site:maxlinerusa.com cured in place supports that they use the term "Cured-in-place Pipe (CIPP)."

I suspect that's enough evidence to redirect Pipe lining to this article and so did that. I don't know if "pipelining" as CIPP is common enough to merit a note on the pipelining article. --Marc Kupper|talk 22:50, 31 December 2012 (UTC)[reply]

Inch

0.1 to 2.8 meters (2–110 inches).

0.1 m = 4 inches

Or is 2 in the correct value?
