Is anyone familiar with CIPP liner for high temperature service? Service temperature is 170 deg F with less than 5% of ketones.
Appreciate your advice.

Two materials used for liners are polyester and vinyl ester. The vinyl esters are usually highly restistant to chemical attack.
Most of the CIPP products are limited to 120-140 Degree F.
You also do not characterize the ketone. The ketone can be a solvent. It will be difficult to predict the effect of the ketone because there will be limited data available on the chemical resistance at that concentration.
You also have to estimate the long term chemical resistance versus short term resistance. There may also be another chemical in the fluid that effects the lining material.
You should get information directly from the CIPP manufacturer. Contact Insitufrom:

BIMR,
Working pressure is atmospheric. This pipe is a 18" corrugated pipe. Waste stream has continuous temperature of 170 deg F and 5% acetone. I contacted insituform but they couldn't help us due to high service temperature.
any recommendations? What is your opinion on cementitious linings?
Appreciate your advice

Pipe is 300 feet. thrice in a year we will have about 10% MIBK coming in contact with pipe for 5 minutes.

I would recommend a chemical resistant FRP pipe such as the Bondstrand 5000.

BIMR,
Bursting this pipe will be expensive (unless I can find CIPP or spray in place options) as we have to burst other minor concrete structures surrounding this area. Also fire water lines run adjacent to these pipes.
Richard,
I feel DIP is not an option as waste water (DI water) at 170 deg F will be corrosive.
Appreciate your thoughts.

Koshy

I guess you are referring to slip lining and grout the annular spaces at the ends.
I didn't mention in my previous conversation that this 300' pipe (straight) has two lateral connections (8") without any trenches to access. If I go for slip lining I need to excavate at this intersection points for tie ins.
If I dont get right CIPP resin, I would go in this direction.
Appreciate your kind advice and time.
