A method for manufacturing boiler tubes includes the steps of removing end caps from a plurality of tubes, the plurality of tubes including at least a first tube and a second tube, cleaning an outer surface of the first tube and the second tube, forming a weld preparation on an upstream end of the first tube, forming a weld preparation on a downstream end of the second tube, welding the upstream end of the first tube to the downstream end of the second tube to form a butt weld, to produce a long tube, and with an automated device, measuring a parameter of at least the first tube and the second tube. The steps of removing the end caps, cleaning the outer surface of the tubes, forming the weld preparations, welding the first tube to the second tube, and measuring the parameter are performed autonomously.

A drain servicing assembly including: an outer housing; an inner containment member, wherein the inner containment member is rotatable proximate a centralized axis; a motor and/or drill secured to the inner containment member; a shaft sub-assembly in communication with the motor and/or drill that includes an outer sheath and a flexible inner shaft that is rotatable independently of the outer sheath; and a guide, wherein the guide enables a user to extract and/or retract the shaft sub-assembly.

Drain cleaning machines having various fluid management provisions are described. The various fluid management provisions serve to direct and collect fluid and debris carried with a drain cleaning cable undergoing retraction into the machine.

Method for treating a service water supply unit of a dental treatment unit, wherein the method has the following sequence of treatment steps: cleaning the service water supply unit using a cleaning agent, preferably a cleaning liquid or a cleaning foam; disinfecting the service water supply unit using a disinfecting agent, preferably a disinfecting liquid.

Apparatus and method for cleaning the inner surface of a pipeline from deposits and for forming a protective coating are disclosed. The apparatus includes a cleaning tool which is caused to move in the interior of the pipeline by a flow of a fluid, the cleaning tool comprising a plurality of guide discs engaging the pipeline surface and mounted along a longitudinal axis of the cleaning tool, an anode positioned inside the cleaning tool, and an impressed current source electrically connected to the anode and the interior of the pipeline, the interior of the pipeline acting as a cathode when current is applied from the current source so that ions flow from the anode, through the fluid, to the interior of the pipeline.

A sterile tube connector for a fluid circuit system comprising a housing. A first opening is configured to receive a first length of tubing in communication with a first chamber. A second opening is configured for communicating with the first chamber when the tube connector is in an open configuration but not in a closed configuration. The second opening is configured to reversibly engage a third opening to form a second chamber. The third opening is configured for communicating with a second length of tubing. A first portion of the housing forming the first opening comprises a material at least partially permeable to a sterilization energy source for sterilizing contents of the second chamber.
