A plug system including: a plug tubular including a tubular body, an upstream tubular connection, and a downstream tubular connection; wherein: the upstream tubular connection and the downstream tubular connection are openings at opposite ends of the tubular body; and a plug assembly arranged in a housing including: a plug; a breaker object; and a seat; wherein: the plug is supported by the seat; the plug assembly has a first position and a second position; wherein in the first position, the plug intact; and in the second position the plug has been broken by the breaker object; wherein: the plug is stationary with respect to the housing in both the first and second position; there is a fluid connection between the upstream tubular connection and the downstream tubular connection: and the tubular body is a single continuous piece; and wherein the plug assembly is entirely arranged within the plug tubular.

Plug assembly

A plug assembly arranged in a housing including: a plug, a breaker object, a seat, a shear ring and an assembly retainer. The plug is supported by the seat and the shear ring prevents the seat from moving in an axial direction. The shear ring is arranged such that when a threshold pressure differential is applied to a surface of the plug, the shear ring shears and allows for axial movement of the seat. The assembly retainer provides axial support to the breaker object, seat, or shear ring. A plug assembly arranged in a plug tubular. The plug tubular made of a single continuous piece.

A plug assembly arranged in a housing including: a plug, a breaker object, a seat, a shear ring and a snap ring. The plug is supported by the seat and the shear ring prevents the seat from moving in an axial direction. The shear ring is arranged such that when a threshold pressure differential is applied to a surface of the plug, the shear ring hears and allows for axial movement of the seat. The plug assembly has a first position, a second position, and a third position. In the first position, the plug is not in contact with the breaker object, in the second position, the shear ring has sheared and the plug is in contact with the breaker object causing the plug to break, and in the third position, occurring during or after the plug makes contact with the breaker object, the snap ring is arranged to lock the seat into place to prevent the seat from moving axially.
