Primary Containment
A New York auto manufacturer has an aluminum sulfate primary containment tank that was decommissioned about a year ago because the product it was holding had eaten two holes in the tank wall. Maple Grove Enterprises was called to remove the existing glass flake tank lining and repair the tank. Since the only access to the tank had been a small hole on the top, we cut a 24" hole into the side of the tank for easier access and safety. The new manway was fabricated in our Arcade facility, delivered to the company, and installed. Contact Us for containment repairs or installation! (Click on any photo for a full-size view.) |

The original glass flake tank lining failed, allowing the acid to eat two holes through the ¼" steel wall. We thoroughly cleaned the tank walls with solvent, welded patches over the holes, and then recoated the outside surface of the tank. |
On the inside of the tank, the hole is covered with metal filler. |

The tank originally had no access, except for a too-small opening at the top. Maple Grove cut a 24" hole in the side of the tank. |
We fabricated covers for the hole at our shop and then installed them on the tank. |

After creating access to the tank, we sandblasted the inside to remove the original tank liner, and then evacuated the leftover media. |
After evacuation, we grind and repair imperfections in the wall. |

After grinding, we thoroughly inspect the inside walls to remove all imperfections, weld splatter, and possible holidays, and then apply metal filler to pits and imperfections. |
Two coats of polyester are applied to the welds and seams, and then the seams, wall, ceiling, and floor are painted with three finish coats. |
