Abstract
A corrosion limiting device for use with a fluid-carrying piping system having a connection formed from first and second components. A seal is carried by the components for forming a fluid-tight seal between the components. The components form a groove external of the seal. The corrosion limiting device includes an elongate member having first and second end portions and a length sufficient to extend around the groove. At least a portion of the elongate member is adapted to seat within the groove for aligning the elongate member on the components. The first and second end portions of the elongate member are fastened together. The elongate member serves to inhibit corrosion of the connection.

A corrosion limiting device for use in an environment with a piping system carrying a fluid and having a connection formed from first and second components, a seal carried by the components for forming a fluid-tight seal between the components, the components forming a groove external of the seal, comprising an elongate member having first and second end portions and a length sufficient to extend around the groove, at least a portion of the elongate member being adapted to seat within the groove for aligning the elongate member on the components and means for fastening together the first and second end portions of the elongate member when the elongate member is extending around the groove, the elongate member providing at least one opening between the groove and the environment for permitting any fluid which has leaked from the seal to pass into the environment so as to inhibit the accumulation of any such fluid within the groove, the elongate member having sufficient circumferential continuity for limiting the ingress of oxygen from the environment into the groove and thus inhibiting corrosion of the connection.
A connection in a piping system which is used in an environment to carry a fluid comprising first and second components provided with respective communicating passages adapted to carry the fluid, a plurality of fasteners carried by the components for securing the components together, a seal carried by the components around the passages for forming a fluid-tight seal between the components, the components having a space therebetween external of the seal and a barrier carried by the components for separating the space from the environment, the barrier providing at least one opening between the space and the environment for permitting any fluid which has leaked from the seal to pass into the environment so as to inhibit the accumulation of any such fluid within the space, the barrier having sufficient continuity for limiting the amount of oxygen from the environment available to the space and thus inhibiting corrosion within the space.
