Seal welds in water storage tanks
Seal welds in water storage tanks
(OP)
I am working on a steel water storage tank. We are using steel W beams to support a steel plate roof. The steel tank fabricator does not want to continuously weld the flanges to the plate because of possible thermal differences between the top and underside of the plate roof that could cause the welds to fail. The civil engineer wants continuous seal welds to prevent bacteria from growing in the spaces between the top flange and roof plate.
Any opinions?

We're currently rehabbing some tanks with severe corrosion issues and requiring the rehab contractor lift the roof plates and recoat the top flange and plate. Then the joint is caulked. As you might expect, this is a major pain you know where.
Expect the tank supplier to fight you to the death on this.

The tank standards leave seal welding as an option. If it's not been specified, it would be an extra to a contract- it's not just a detailing issue.
