High temperature leak prevention for piping components and connections

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,
• wherein the pipe end in contact with the primary seal and the secondary seal defines a barrier to media flowing through the pipe, and
• further wherein the socket cup is configured as a valve body for a valve assembly comprising a stem and a packing gland, wherein the primary seal is a gasket configured for sealing the stem, and further wherein the secondary seal is positioned in proximity to the packing gland and the gasket.

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,
• wherein a single primary seal is positioned in the primary sealing recess, the primary seal comprising an elastomeric material having a service temperature,
• wherein a single secondary seal is positioned in 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 and between about 316° C. and 538° C.,
• wherein the socket cup and the secondary seal are configured to facilitate flow of the secondary seal upon melting into the primary sealing recess, and
• wherein the secondary seal comprises a brazing alloy or a solder alloy composition.
