Would sodium bicarbonate tables be affective at mixing the water in the sags to help transfer the heat though the pools of water. Maybe m mixed with Detergent to help carry the water?

So because no one has solved a problem before it's unsolvable? I wouldn't inject it into steam. I would deliver it as a pellet and it would be easy to time delay with a coating. Increasing waters thermal conductivity would also help. I'm not looking for a magic bullet but 20F degrees in...

#LittleInch The length of time is determined by diameter and length along with temp readings. 8"_15" under 400ft takes 30min to reach temp130F on the low end and an hour or longer on the long end. Then held for 2 hours 24"_36 can require multiple steam units several hours to reach temp and...

We do use hot water to cure line. There are 2 methods to epoxy resin CIPP. Steam cure and water cure. Water is much more time consuming and expensive. You can still have the issue with cold spots when using water. You are all underestimating how much heat the ground( especially when water...

This is real world application. I do this every day and my numbers are correct. Part of the problem is delivering enough energy density to the liner before ground water wicks it away. Steam also collapse on itself as it transfers heat (the whole reason we have condensation). The temp of the...

There needs to be enough thermal mass to get the reaction to happen in a timely manner. I'm trying to improve on an existing industrial process CIPP. The host pipe (underground sewer) along with ground water stays at a constant 55F year round and is pulling heat away from the active process...

#georgeverghese. Thank you for your feedback. To clarify my Temps were in F. Curing temp of liner is 130F. I'm interested in HTP20 heat cable but I think it would be cost prohibited. Average line length is 400ft sometimes as long as 1500ft. I am definitely going to look into it. Do you have...

I need to remove the condensation from sags in the pipe. The process is CIPP lining. We use a temperature activated resin to cure a soft liner that is blown into an existing sewer line. The line is kept at 30 degrees installed with air then brought up to temp with a steam unit that provides 270...

I work for a company that uses steam to cure new sewer pipe. In the process condensation builds up in low spots (sags in host pipe) and prevents the material from curing. I'm working on an additive to be injured (liquid or pellets)into the pipe to reduce the boiling point of condensation to...
