Abstract

The DC60 (18/10/44) low profile secondary seal has a pipe positioned over the primary seal used. Benefits from cladding plates The pipe will be connected to the floating roof. Leak proof at the end adjacent to The outer shell of the tank is connected to the head plate covered by the extension plate. In use, the pipe is placed on a stepping plate with sufficient force to secure the seal at the end of the seal to the outer shell of the tank. The low profile secondary seal has a pipe positioned over the primary seal used. Casting from the cover plate The pipe will be connected to the floating roof. Leak proof at the end adjacent to The outer shell of the tank is connected to the head plate, covered with an extension plate. In use, the pipe is placed on a spacer with sufficient to secure the end seal to the outer shell of the tank.
