I hear dryer cans are difficult to repair when they get a steam cut in them.  I found an interesting article that speaks to NDE testing and how it can help extend the service life of components in the plant.  Belzona has this nice worldwide “intranet” with some newsgroups and I was reading the thread about this repair.  Seems these dryer cans are a world-wide problem.

Do you know that Belzona has a repair procedure for sealing these leaks?

MBX has a beautiful little tool that is kind of like a grinder but gives us a better profile for the Belzona to adhere to the substrate without all that blasting.  In some cases grit blasting is the only option and for dryer cans we recommend the spongejet system to keep the dust down.

Belzona 1321 (Ceramic S-Metal) is applied onto the steam cut, just enough to wet the groove, then Belzona 1311 (Ceramic R-Metal) is pressed in (with your thumb) to the 1321 which in turn presses the 1321 deeper into the cut.

Allow to dry and then pressure test the dryer can to be sure the leak is fixed.  Don’t you just love it when I make a repair sound so simple?  It’s cost effective too.  Reports around the globe have this repair lasting anywhere from four to sixteen years.

How can we help you repair, protect and improve your component equipment?
