ABSTRACT:
A pressurized tank construction having a resilient protective skirt attached to a head of the tank. A ring is welded to the tank head prior to heat treatment of the tank. After heat treatment a second ring carrying an annular resilient skirt and having a larger diameter than the first ring is secured directly to the first ring so there is no direct attachment of the second ring to the tank. The skirt provides a stable support for the tank and cushions the tank during handling and transporting. With smaller sized tanks a metal ring having a laterally extending outer lip is welded to the tank head and a resilient ring is snap-fitted into engagement with the lip to provide a support for the tank.
