Leaking slurry tanker

Phil Iam · 17-08-2014 07:25PM #1

When I was filling the slurry tanker yesterday I noticed a small squirt of slurry come out at the under side of the tanker, the tanker is 20 years old but I would like to get another few years out of it, It is only used about 4 days a year.
I cant imagine a weld doing the trick as it must be very rusty to get holed in the first place,
what is the best repair job I can do!

Clean of the rust around the area of the leak and get a patch and weld it on over the hole it will leak a bit at first but will block up over time.

make sure if welding that hatches on tanker are open

I normally take the back door off and get and get a good clean out before welding.

Devcon will seal anything.

Small hole just put a trek screw in, bigger ones open off the back and put a bolt through the hole with a bit of rubber/tube and washers both sides
Our lady will never implode as there are that many holes in it hate spreading in dry times as there is never any soft dirt around to plug holes with

Tek7 is mighty stuff

Roll her over with the loader, and weld on a good big patch. You may have to go well away from the rust hole to find metal sound enough to weld to. Almost impossible to weld above your head on this kind of project, hard enough with clean new steel............

we brought ours down to local engineering works-after oh rolled it- it was only the drawbar that needed welding but they lifted the tanker up to get in to weld it properly.

Its grand when you have the equipment to repair them like that. Make it look easy.

OP id rinse the tanker out well with water first before going near it also

Would it be easier to weld from the inside? Might no harm to inspect the whole lot inside.

Bit of flat plate and ventilate the tank. The fumes won't be a problem if you haven't much to do but be careful.

What ever slurry does to the steel you will need to strip away the top surfaceto weld to it weakening the stucture more. at least on the outside there should only be the paint to clean off.

Inside would hold up better to the pressure, but you'd want to clean the metal back to bare pretty well, not to mention the obvious safety factors involved. I'd weld on the outside of the tank personally, clean well back from the crack to find good metal, and use a decent sized patch. It's also much easier to inspect your welds afterwards, and reweld if you need to.

I'd say don't be going into the tank.. There are too many risks involved and plenty of tanks are repaired well from the outside.. If you think the position of the weld is too challenging for yourself get a lad in for a few quid and do it well..

We made a small repair on ours last spring..
I have a small mig welder and I patched up the actual hole best I could with that..
Cut a decent sized plate and cleaned back the steel well and used the arc for that.. rub of liquid metal repair stuff round the weld and it was airtight.

Very true, dont bother your arse going into the tank, some things matter more (like your life!!)

I filled a patch with expanding foam insulation. I've gotten another year ou of it so far

Weld a patch onto the outside of tank. Use a mig if you can. If not use 2.5mm rods. Open up the tank for a day or two before hand. Disconnect the tractor from the tanker before welding it (to protect altenator). Don't go into tank to weld it, its not worth it, not just from a safety point but the steel will be cleaner on the outside.
I have become an expert on welding patches on slurry tanks. :mad:

I could probably reach the hole at stretch from outside.
