Patent ID: 7900654

Claim:
A removable vented pipe cover for covering an open end of an industrial plant pipe, the pipe cover comprising: a flexible tubular body portion having a first body end and a second open body end; a flexible, planar end wall connected to said first body end defining an inside cover space configured for covering said open end of said industrial plant pipe; a venting component connected to said flexible end wall, said venting component being selected from the group consisting of a mesh portion in said flexible end wall, a plurality of openings in said flexible end wall and a openable pressure seal in said flexible end wall, said openable pressure seal being in an open position when a pressure imbalance exists between an inside of said industrial plant pipe and an outside of said industrial plant pipe and in a closed position when no pressure imbalance exists between the inside of said industrial plant pipe and the outside of said industrial plant pipe; and a flexible, planar, vent panel removably disposed on said flexible end wall and covering said venting component that is manually operated for equalizing air pressure between an inside and an outside of said industrial plant pipe when the pressure in said industrial plant pipe is either below or above the pressure outside of said industrial plant pipe and when said vent component is said mesh portion or said plurality of openings, said flexible vent panel being manually moved to an open position when a change in pressure is expected between an inside of said industrial plant pipe and an outside of said industrial plant pipe and manually moved to a closed position when a change in pressure is not expected between the inside of said industrial plant pipe and the outside of said industrial plant pipe.
