Standard Pipe Coupling Rusted On

Standard Pipe Coupling Rusted On

PostBy: daluds On: Tue Nov 22, 2016 1:41 am

I'm going to look to buy one of the split couplings since I had a big chunk of coal stuck in the auger and caused the sheer pin to break off.

Took me hours to get the coupling off of the auger pipes to clear it. What a pain. I almost pulled out my plasma cutter to cut it off, but ended up using some liquad wrench and bigger hammer.

I tried sealing the gap between the pipes, but water still got into the coupling from the wet coal. Would applying grease help?

Anyone have a link to buy a new motor? The one I have sounds like it might have a bad bearing.

Thanks,

Dave

There is nothing wrong with using the standard pipe coupling (non-splitting), just remember when you put them back on use a liberal helping of anti-sieze. I mean really slobber it up!

I have done this for years and have never had to hammer on one to get it off. I am sure a nice heavy grease would do the trick as well, but Permatex will probably hold up better over time.

Just like the Frank's Red Hot sauce commercial: "I put that sh#t on everything!!!" :funny:

I wonder if this would help, sprayed over the coupling and surrounding area after assembly?

I'll try both. I didn't think about using anti-seize. I also think the thin tape gets scraped off and causes it to get stuck too.

I had to use grinder attached to drill to take off rust inside the collar to get it back on. What a pain...

Thanks!

There is always rubber tape. It bonds to itself when applied.

If you use either of the options I listed, you'll still have to cut it away when you want to change it, but it *should* help keep the intrusion out of the joint.

But keep in mind, it ONLY keeps the moisture away that comes from the OUTSIDE. It will still absorb stuff from the INSIDE of the pipe as coal moves through it.

I use a fernco rubber fitting to connect the bin pipe to the coal pipe. Its been there several years, no problems to date. I have had one shear pin break, the fernco was easy to loosen and slide up the coal pipe so that I could split the auger to clean things out.
