Tank Fabrication/Shell Repair
The expectations for tank repair and construction have changed throughout the last 100 years. Standard practices in the 1940’s are not the same as today.


Consequently, many of the welded steel and riveted storage tanks across the country are in need of shell modification, replacement, and repair.
CALAYA offers the following tank shell repair and replacement services:

    • Complete Shell plate or shell ring replacement
    • Nozzle repair and replacement due to improper weld spacing
    • Door sheet repair and replacement due to improper door sheet installation

    If your facility or community is in need of additional capacity the solution may be as simple as adding additional shell rings to your tank. We can increase the storage capacity of your tank if you provide us with the following information

      • Current Tank Diameter and Height
      • Thickness of each shell ring
      • Thickness of top angle
      • Product Specific Gravity
      • Tank location
      • Foundation details or site soil bearing
      • Desired new storage volume
