The header delivery system is insertable in the header pipe and has a launcher pipe for launching an inspection or cleaning tool to the process tube. A tube coupler for coupling to the process tube and a bumper are connected to the launcher pipe. A jack apparatus is configured to position the tube coupler and the bumper. A wedge assembly is connected to the launcher pipe and has a first actuating wedge and a first extension wedge. A first linear actuator is connected to the first actuating wedge and is configured to move the first extension wedge and the tube coupler mount apart from one another to position the tube coupler and the bumper from a retracted position to an extended position.

A pipe protection device which is provided at a supply-side coupler provided at an end portion of a supply pipe which supplies a heat exchange medium to a heat exchange unit, and a discharge-side coupler provided at an end portion of a discharge pipe from which the heat exchange medium, which is supplied from the supply pipe to the heat exchange unit, is discharged, includes a supply-side support part having a recess along a contour of part of the supply pipe, a discharge-side support part having a recess along a contour of part of the discharge pipe, and a connecting part which supports the supply-side support part and the discharge-side support part at a predetermined interval and connects the supply-side support part and the discharge-side support part to a housing constituting a server.

A plant for continuously cooling foodstuffs includes a container suitable to receive such foodstuffs continuously moved by a movement member and refrigerant apparatus for cooling such foodstuffs during the movement thereof, the movement member being a pump; the plant includes a spiral duct preferably arranged around the container wherein the pump continuously directs and moves the foodstuffs to be cooled and in which there is directed a cryogenic fluid, along at least two different turns of the spiral duct there being arranged apparatus for injecting of the cryogenic fluid.

A heat exchanger connected to a refrigerant pipe includes: heat transfer tubes; and a header that connects the refrigerant pipe and the heat transfer tubes, and that forms a refrigerant flow path between the refrigerant pipe and the heat transfer tubes. The header includes a first member that includes a first plate-shaped portion, and a second member that includes a second plate-shaped portion that is stacked on a heat transfer tubes side of the first plate-shaped portion. The first plate-shaped portion has a first opening that forms the refrigerant flow path. The second plate-shaped portion has a second opening that forms the refrigerant flow path. When viewed in a stacking direction of the first plate-shaped portion and the second plate-shaped portion, the second opening and the first opening overlap each other at a first region and at a second region that is different from the first region.

A heat exchanger is provided, including a heat exchanger core. The heat exchanger core at least includes a first core part, a second core part and a third core part which are stacked. The first core part, the second core part and the third core part are formed by stacking plates. The third core part is located between the first core part and the second core part.
