Drilling through boiler tube
Drilling through boiler tube
I need to drill into the boiler tube to mount various items and would like to know if it would OK to drill through holes and lock-tite stainless steel studs in? Thanks for your advice.
Re: Drilling through boiler tube
drill and tap, then use loctite to seal, i am not sure i would use stainless tho.
I have always used grade 8 steel cap screws with the heads cut off, some of them have been in
place for the last 18 years

What would be the objection of using stainless steel studs?

Would zinc plated screws be better. I am using 5-40 UNC screws.

Re: Drilling through boiler tube
Just throwing out an idea: weld tabs onto the boiler and drill and tap them. Thus the boiler remains intact. If the tabs are low profile they'll be hidden under the boiler lagging. That's what I've done with success. A 5-40 tap or screw breaking off in a boiler shell does not sound like fun.

As Greg Lewis suggested, I tack welded metal tabs onto the boiler shell that were drilled and tapped for handrails, and more.
Tabs also provide side support for the domes.

Keeping in mind I am not a boiler maker, I'd suggest that zinc isn't any help. The pH of the boiler water is sure to dissolve the zinc quickly, but on the positive side, if the pH is high enough, that, alone, protects the boiler from corrosion.

Would brass studs be OK on boiler attachments?

No brass either as it is an alloy...look up what is in brass.
Stay with carbon steel.
