Abstract
A connection socket for a tubular connection that includes: a socket cup having a metal alloy composition and a sealing portion, the sealing portion comprises a primary and a secondary sealing recess; a primary seal positioned within the primary sealing recess, the primary seal comprising an elastomeric material having a service temperature, and a secondary seal positioned within the secondary sealing recess, the secondary seal comprising a metal composition. Further, the secondary seal has a melting temperature at or above the service temperature of the primary seal.
Claims20
A connection socket for a tubular connection, comprising:
- a socket cup having a metal alloy composition and a sealing portion, the sealing portion comprising a primary sealing recess and a secondary sealing recess;
- a primary seal positioned within the primary sealing recess, the primary seal comprising an elastomeric material having a service temperature;
- and
- a secondary seal positioned within the secondary sealing recess, the secondary seal comprising a metal composition,
- wherein the secondary seal has a melting temperature at or above the service temperature of the primary seal.
A connection socket for a tubular connection, comprising:
- a socket cup having a metal alloy composition and a sealing portion, the sealing portion comprises a primary sealing recess, a secondary sealing recess, and a tertiary sealing recess;
- a primary seal positioned within the primary sealing recess, the primary seal comprising an elastomeric material having a service temperature;
- a secondary seal positioned within the secondary sealing recess, the secondary seal comprising a first metal composition;
- and
- a tertiary seal positioned within the tertiary sealing recess, the tertiary seal comprising a second metal composition,
- wherein the first and second metal compositions of the respective secondary and tertiary seals differ, and
- further wherein each of the secondary and tertiary seals has a melting temperature at or above the service temperature of the primary seal.
A tubular connection, comprising:
- a socket cup having a metal alloy composition and a sealing portion, the sealing portion comprises a primary and a secondary sealing recess;
- a primary seal positioned within the primary sealing recess, the primary seal comprising an elastomeric material having a service temperature;
- a secondary seal positioned within the secondary sealing recess, the secondary seal comprising a metal composition;
- and
- a pipe having a metal alloy composition and comprising a pipe end in contact with the primary seal and the secondary seal,
- wherein the secondary seal has a melting temperature at or above the service temperature of the primary seal, and
- further wherein the pipe end in contact with the primary seal and the secondary seal defines a barrier to media flowing through the pipe.
