Abstract
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 (11) in a tubular body (12) comprising:
- a plug (2);
- a breaker object (32);
- a seat (4);
- and
- an assembly retainer (6)
- wherein:
- the plug (2) is supported by the seat (4);
- the assembly retainer (6) supports the plug assembly;
- and
- the assembly retainer (6) is stationary with respect to the housing (11), and the assembly retainer (6) is a separate element from the tubular body (12);
- further:
- the plug assembly has a first position and a second position;
- wherein:
- in the first position, the plug (2) is not in contact with the breaker object (32);
- and
- in the second position, the plug (2) is in contact with the breaker object (32)
- wherein the assembly retainer (6) is fixed to the tubular body (12) by a retainer connector (62).
A plug system (200) comprising:
- a plug tubular (1) comprising a tubular body (12), 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 (12);
- and
- a plug assembly arranged in a housing (11) comprising:
- a plug (2);
- a breaker object (32);
- and
- a seat (4);
- wherein:
- the plug (2) is supported by the seat (4);
- the plug assembly has a first position and a second position;
- wherein in the first position, the plug (2) is not in contact with the breaker object (32);
- and
- in the second position the plug (2) is in contact with the breaker object (32);
- wherein:
- there is a fluid connection between the upstream tubular connection and the downstream tubular connection:
- and
- the tubular body (12) is a single continuous piece;
- and
- wherein the plug assembly is entirely arranged within the plug tubular (12).
A method for assembling a plug system (200), the plug system comprising:
- a plug tubular (1) comprising a tubular body (12), 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 (12);
- and
- a plug assembly arranged in a housing (11);
- wherein:
- there is a fluid connection between the upstream tubular connection and the downstream tubular connection;
- wherein the plug assembly comprises a plug (2), a breaker assembly (3) and a seat (4);
- wherein the tubular body (12) is a single continuous piece;
- the method comprises the steps of:
- (a) obtaining the plug tubular (1);
- (b) inserting the plug assembly into the housing (11) in the plug tubular (1);
- comprising the steps of:
- (i) inserting the plug (2) into the housing (11) through the downstream tubular connection;
- (ii) inserting the seat (4) into the housing (11) through the downstream tubular connection;
- (iii) inserting the breaker assembly (3) into the housing (11) through the downstream tubular connection;
- and
- (c) securing the plug assembly in the housing (11).
