A flange plate closure for accessing a containment vessel has a metal base plate, having an interior and an exterior surface, at least one vertical metal tube having an open end, a metal flange ring at said open end defining an upper planar surface, and a lining made of non-corrosive material. The lining is disposed in overlying relation to the interior surface of the base plate, the interior of the tube and the upper planar surface of the flange ring. The lining is rigid, and is mechanically affixed to the metal components. The lining is made of Ultra High Molecular Weight Polyethylene.

An aerator pad for a railroad hopper car has a fabric body member that overlies an aeration assembly slope sheet. The body member has a perimeter portion with indentations formed in the edges thereof. A gasket is molded to the perimeter of the body member. Bolt holes in the gasket are spaced from the fabric so that no edge or perimeter portion of the fabric is exposed to atmosphere. The gasket is located between mating flanges of the aeration assembly and car body. Spacer buttons lift the body member off the slope sheet and a wear pad prevents vibration induced deterioration at the gas inlet opening in the slope sheet.

A latch system for retaining hatch covers on railroad cars can accommodate any hatch cover type made by any car builder. The latch has a universal arm with a custom-made hinge adapter at one end for pivotally connecting the arm to any hatch design or cover type. The other end of the arm mounts a catch adaptor which receives a catch bolt for retaining the arm in a closed position. The arm also has fittings for accepting brackets and wings for vented hatch covers.
