Abstract
A protective flange is provided for the protection of a protrusion or valve on the surface of a tank car. The flange has an inner arcuate wall and an outer deflection portion for receiving impacts. The inner wall is annular and spaced from the protrusion to provide for mounting over the protrusion without cutting into the tank car. The outer portion includes longitudinally extending slope portions and vertical side walls welded to the tank car surface. The flange is tapered to deflect impacts received at the sides of the flange. The outer deflection portion and the inner wall define a closed space surrounding the protrusion or valve. Steam connections may be made to the flange to introduce steam into the closed space for heating the valve.
