Adhesive use on rubber seals of Weil McLain Boilers

JackEnnisMartin

I would like to ask a question of the folks who put together commerial /industrial size Weil Mclain boilers. I am sure you have had the fight of trying to mate up two sections and trying to keep the rubber gasket in place at the same time. I have been using 3M spray adhesive to tact the gaskets in place and then bringing the sections into place. The adhesive is stated to be safe for rubber surfaces -- and we use only enough to "tact" the seal in place. So far we have not experienced any problems at all. My question is have other people tried this and have you met with any problems? I have to say ,in my opinion it is a very good product[ no 3M is not paying me]. We have also found the 3M citrus cleaner to be a fine way to clean oil or grease off the seal intents on the boiler sections. We all know ;no petroleum based material can be used on Weil McLain neoprene gaskets ,so the citrus product seems to work really well.
I would like to reply to the chap regarding "sand" in the eyes after a day of welding. I have found out of all the products on the market to relieve this feeling -- diluted tea works really well, I cannot tell you why I am certainly not a doctor:but, it does help. One other point of interest: here in Manitoba the Department of Mechanical inspections no longer allows relief valves to be run off the sections of a cast iron sectional boiler -- you have to mount the relief in the header piping. They say the reason is a section can be run dry if the relief really lets go and damage can result to the section:what are the thoughts on this?
Thanks and hug your kids they are the future we are the past. Jack Ennis Martin

If its like the USA

Tell him to go fly a kite, aye! He better have a code to back that up. No inspector makes the law (or even really interprets it) he is only licensed to ENFORCE the laws adopted in that jurisdiction.

If a section goes out because of it "emptying" before the other sections can refill it, oh well, that's the price of doing business. The idea of the header sounds logical in a messed up sort of way, but actually, if the pop-off is in the supply header it could drain the front section just as quickly.

Also, the pop-off has to be located in such a location as to have immediate feedback of boiler pressure; no valve can be located between the boiler and the PRV.

At least here in the US.

Pressure relief valves on boiler sections

Thanks for your reply and we do not agree with them especially when the makers of the equipment indicate thats where the relief goes.Here they are God [ and I have tried] to argue with The Department of Labour. They say it is our way or you are not going to get your operations permit. If we are upset, you should see the professional engineers ,when they are told they have the blow off piped in the wrong place -- not happy campers!
