Base Ring & Saddle Height

Standard Ring Base

Ring bases come standard in 4″ or 6″ heights based on the diameter of the tank and are designed to stabilize vertical tanks. Our Engineering department will determine the thickness of the base, based on the total weight of the tank and it’s contents. Bolt down pads are provided.

Ever wish you could get both hands to that base head fitting? The added height on these monster base rings provide enough room to work comfortably when accessing the lower head fitting. Be careful of the overall room height when ordering!! These extended base rings will add 8” to the overall height. The extra height base ring is only available on bare and topcoated tanks.

Saddle Support

Two saddles are required for most horizontal pressure vessels. On larger tanks, three or more saddles may be necessary. Saddles can be shipped lose or secured to the tank. All saddles have 3/4” or 1“ bolt holes for securing. We can also provide taller saddles if more clearance is needed.
