Agricultural Tank Repair

Agricultural tanks serve a variety of purposes. They can easily be damaged, especially when you consider all of the heavy equipment often used around them.

Whether an agricultural tank has a small two-inch crack, a 5-foot-long crack, or a hole, this type of damage can easily be repaired with one of Polyvance’s nitrogen plastic welders. In this case, this giant polyethylene tank had a large hole cut into it that is no longer needed.

In this video, we will show you how to repair a hole this size using a nitrogen plastic welder and a sheet of polyethylene.

Thanks for taking the time to make the video! How’s the repair holding up years later?

Dang, nicely done.
I just burned a big hole at the edge of my airbox on my dirtbike.
Like 2 cm wide and 10 cm long.
The airbox is thin.
So i think I can fix it.
Thanks for the video!

I want to cut down some tanks like this to make a custom fit. Would this weld work for that much work?

Can you weld on a 28% nitrogen farm tank once it has been emptied?

[justinburkhart]

Would you use the same welder and process if repairing a crack

Plz, also make a video to fix and repair, the missing part of plastic body of a sandwich maker

Hi Polyvance,
What would you charge for this kind of repair?

[hickorycattlecompany]

How about on a smaller tank...where it leaks around one of the bolt holes that holds it on the metal frame?
