ABSTRACT:
A method of manufacturing a tube includes the steps of preparing a composition using ethylene vinyl acetate, extruding the composition to form a tube, and cooling the tube with the tube in a substantially straight configuration so that the tube is substantially set in a substantially straight configuration. Moreover, a system for creating a frozen surface on a medium includes a mechanism for exchanging thermal energy between a medium and a coolant, a mechanism for removing thermal energy from a coolant, and a mechanism for transporting a coolant between the mechanism for exchanging thermal energy between a medium and a coolant and the mechanism for removing thermal energy from a coolant. The mechanism for transporting a coolant includes first and second pipes and mechanism for releasable connecting the first pipe to the second pipe so as to prevent the first pipe from moving axially relative to the second pipe in a first operational state, and to allow the first pipe to be moved axially relative to the second pipe in a second operational state. Additionally, a system for creating and maintaining a frozen surface on a medium includes a mechanism for exchanging thermal energy between a medium and a coolant, the mechanism for exchanging thermal energy between a medium and a coolant having a substantially uniform cross-sectional area for passing a coolant therethrough. The system also includes a mechanism for removing thermal energy from a coolant. The system further includes a mechanism for transporting a coolant between the mechanism for exchanging thermal energy between a medium and a coolant and the mechanism for removing thermal energy from a coolant. The mechanism for transporting a coolant is connected to the mechanism for exchanging thermal energy between a medium and a coolant so that substantially all of a coolant flowing from the mechanism for transporting a coolant to the mechanism for exchanging thermal energy between a medium and a coolant flows directly from the mechanism for transporting a coolant into the mechanism for exchanging thermal energy between a medium and a coolant.
