摘要： A utilities tube assembly (200) including one or more utilities tubes (200A, 200B, 200C). The one or more utilities tubes (200A, 200B, 200C) each include at least a first tube (302, 304, 306) and a second tube (302, 304, 306), where each of the first and second tubes (302, 304, 306) include a base material having a specified mechanical characteristic; and a weld interface (410) proximate an end of each of the first and second tubes (302, 304, 306). One or more of the utilities tubes (200) includes work hardened weld assemblies (310A) joining the first and second tubes (302, 304, 306) at the respective ends. The work hardened weld assemblies (310A) include: a weld fusion zone (406) between weld interfaces (410) of the first and second tubes (302, 304, 306). In a welded configuration (310A) the first and second tubes (302, 304, 306) proximate the respective ends have an end profile different relative to an overall profile of the first and second tubes, the weld interfaces are stacked between the weld fusion zone and the base material of the respective first or second tubes; and in a work hardened configuration the respective ends of the first and second tubes (302, 304), having the end profile, are deformed relative to the welded configuration to match the overall profile of the first and second tubes (302, 304), the weld fusion zone and the weld interfaces are deformed into the base material, the weld interfaces are deformed between the stacked weld fusion zone and the base material of the first and second tubes, and the weld fusion zone is work hardened and the weld interfaces of the first and second tubes are work hardened between the work hardened weld fusion zone and the base material of the first and second tubes based on the deformation of the weld fusion zone.

摘要： A device (100) for heat-treating water is provided, comprising a confined heating zone, a passageway (15) for transporting the water to said confined heating zone (23) so as to facilitate heating of the water, a controller (27) for preventing the heated water from leaving the device (100) until pathogens entrained in the heated water are killed; and an antimicrobial substrate (20) for preventing pathogens entrained in unheated water from leaving the device (100).
