ABSTRACT:
A steel tank construction having a resilient protective skirt. The tank has a dome-shaped end head and a plurality of threaded studs are arranged in a generally circular pattern and extend outwardly from the head. A metal ring is provided with a plurality of outwardly extending projecting areas and each area is provided with an opening that receives one of said studs. An annular rubber-like protective skirt is vulcanized to the outer surface of the ring. Nuts are threaded on the outer ends of the studs to removably secure the ring to the tank head. The construction of the invention enables the protective skirt to be applied to the steel tank without welding and after annealing. As the ring and protective skirt are removably connected to the tank head, the ring can be removed in the field for replacement of the skirt if it becomes worn or damaged.
