UL 142 Cylindrical Double Wall Tanks

Because so many industries need a way to store new and used combustible fluids, we at MMI Tank are able to design and build UL 142 cylindrical double wall tanks to fit your exact needs.
For your standard outdoor, rough and ready for anything applications, our double wall tanks are your best bet. With 2 steel walls from 7 gauge to 1 ¼ inches thick, it’ll take more than an accidental bump to compromise the structural integrity.

If you have limited space on the ground, we can build you a vertical tank on a platform. We can also design fabricate and install ladders, stairs and platforms to make tall tanks accessible for your team members.

If you need it laying down and out of the way, we can fabricate the necessary skids, supports or saddles to safely store your horizontal tank.

We build our tanks tough, with expertly done fillet welds on all the joints, flat flange heads and a huge variety of coatings to minimize wear and tear, you can be sure that your tank will be built to last.
