Abstract
Apparatus to protect sealing surfaces of thief hatches are disclosed. An example apparatus includes a first portion that is attachable to a tank, wherein the first portion includes a first opening, and a second portion that is pivotably coupled to the first portion. The example apparatus is structured to provide access to an aperture in the tank via the first opening when the second portion is in an open state and maintain a pressure of the tank within a specified range by selectively separating one or more seals from one or more corresponding sealing surfaces when the second portion is in a closed state, wherein the second portion includes the one or more seals and the one or more corresponding sealing surfaces.
