Clamping device and an associated method thereof

A turbine assembly comprising:

• a combustor-can;
• and
• an axial fuel staging system coupled to the combustor-can, wherein the axial fuel staging system comprises a fuel injector and a conduit assembly, wherein the conduit assembly comprises a conduit (138) that is clamped to the combustor-can with a clamping device comprising:
• a sheet metal comprising a plurality of first segments and at least one second segment,
• wherein each of the plurality of first segments and the at least one second segment comprise a conduit-facing end and an outwardly-extending end, wherein the conduit-facing ends are joined to each other along a lateral axis of the sheet metal and configured to wrap around the conduit in opposite directions, wherein the outwardly-extending ends of the plurality of first segments extend in an opposite direction to the outwardly-extending end of the at least one second segment, and wherein each of the outwardly-extending ends is bent at a respective bend angle relative to a longitudinal axis of the sheet metal, towards a respective conduit-facing end of a respective one of the plurality of first segments or the at least one second segment;
• a plurality of wedge-washers, wherein at least one wedge-washer is disposed on each of the plurality of first segments and the at least one second segment, wherein the at least one wedge-washer comprises a sidewall inclined in a direction opposite to the bend angle and in contact with a respective outwardly-extending end of each of the plurality of first segments and the at least one second segment;
• and
• a plurality of fastening members with at least one fastening member disposed on each of the plurality of wedge-washers for applying pressure on the respective wedge-washer along radial and longitudinal axes of the sheet metal and clamp the conduit to the combustor-can.

A method for clamping at least one conduit to a combustor-can, comprising:

• obtaining a sheet metal comprising a plurality of first segments and at least one second segment,
• wherein each of the plurality of first segments and the at least one second segment comprise a conduit-facing end and an outwardly-extending end and wherein the conduit-facing ends are joined to each other along a lateral axis of the sheet metal;
• wrapping the conduit-facing ends of each of the plurality of first segments and the at least one second segment of the sheet metal around the conduit in opposite directions;
• extending the outwardly-extending ends of the plurality of first segments in an opposite direction to the outwardly-extending end of the at least one second segment;
• bending each of the outwardly-extending ends at a respective bend angle relative to a longitudinal axis of the sheet metal, towards a respective conduit-facing end of a respective one of the plurality of first segments or the at least one second segment;
• disposing at least one wedge-washer of a plurality of wedge-washers on each of the plurality of first segments and the at least one second segment such that a sidewall of the at least one wedge-washer is in contact with a respective outwardly-extending end of each of the plurality of first segments and the at least one second segment, wherein the sidewall is inclined in a direction opposite to the bend angle;
• disposing at least one fastening member on each of the plurality of wedge-washers for applying pressure on the respective wedge-washer along radial and longitudinal axes of the sheet metal;
• and
• clamping the at least one fastening member to the combustor-can.
