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)

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)

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)

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)

Inch

0.1 to 2.8 meters (2–110 inches).

0.1 m = 4 inches

Or is 2 in the correct value?
