My coal Vac system works quite well but for 1 90 degree elbow. It is at the end where the coal is probably travelling the fastest and wear out the outside edge and a leak occurs. I usually get 3 months out of an elbow before I have to replace it @$2.50.
Yesterday I replaced it after just 2 months.
So as I am limited in space I need to stay with this size elbow , which is a sweep.
Wondering about adding some type of "wear strip" on the interior?
Any thoughts would be great!
Replacement $ is not the issue annoyance is!!
Thanks!

Can you squeeze a long sweep 90 in there? Mine are going on 4 years, using 6 tons per year...

Someone already solved this wear issue some time ago.

Not many problems found now days hasn’t already happened and brought here for discussion.
What I’m saying is that with some effort your answer can be found in archives. The “Search” feature is your key to a wealth of existing hard work others have put forth. It truly is a wonderful asset at your fingertips. 😀.

Here’s I’ll do it for you this time...

You can also use a tee with the end plugged. When it runs, the plugged end fills with coal and acts as a wear surface for the rest of the charge. When the charge stops, most of the plugged coal falls out.
Look up a product called the Pellbow. This is just a poor man's Pellbow.
