The invention relates to a method for stripping a material residue from a metering nozzle, wherein the metering nozzle with the material residue is guided past a stripping element such that the material residue comes into contact with the stripping element and is stripped from the metering nozzle, characterized in that the stripping element performs a closed rotational movement by means of which a segment of the stripping element first of all reaches a stripping position, in which the material residue is stripped from the metering nozzle and at least some of the material residue remains adhering on the segment, is then guided with the material residue adhering thereon to a separating position, in which a separating unit is used to separate the material residue from the segment of the stripping element, and is guided back to the stripping position to receive a further material residue. Furthermore, the invention also relates to a device for stripping the material residue.

A pipe cleaning tool is provided. A pipe cleaning tool, for preparing an exterior surface of a pipe and an interior surface of a fitting for joining the pipe to the fitting, comprising a central tubular member having a coupling member optionally coupled to a rotary tool. An interior pipe cleaner having a first polishing means surrounding an exterior of the interior pipe cleaner, the interior pipe cleaner coupled to a first end of the central tubular member and a tubular exterior pipe cleaner having a second polishing means surrounding an interior of an opened end of the tubular exterior pipe cleaner, the tubular exterior pipe cleaner coupled to a second end of the central tubular member.

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.

A lubrication device, a lubrication system and a method are for applying a lubricant from a lubricating-fluid reservoir to an internal threaded portion of a pipe body. The lubrication device includes: a rotary device having: first and second coupling parts, and fluid passage for carrying the lubricant from the first coupling part to the second coupling part. The first and the second coupling parts are arranged to rotate relative to each other around an axis that coincides in the main with the longitudinal axis of the pipe body. An applicator body is connected to the second coupling part to allow rotation around the rotational axis of the rotary device. The applicator body has a fluid passage with an outlet for carrying the fluid to the applicator surface as the fluid passage in the applicator body is in fluid communication with a corresponding fluid passage in the rotary device.

The present disclosure relates to predicting blockages in underground ducts. According to one aspect, there is provided a computer-implemented method of identifying one or more locations along a route for an underground duct which indicate a blockage risk, the route extending between two ends, the method including obtaining a terrain elevation profile for the route; estimating a duct elevation profile for the route based on the terrain elevation profile; and predicting one or more blockage risk locations along the route by determining where water entering the duct from each of the two ends would settle, based on the duct elevation profile.

A fluid test system for checking the integrity of connections and welds in a fluid component includes a first nitrogen source selectively connected to first and second isopropanol tanks, a fluid line circulation circuit, a drain selectively connected to the fluid circulation line, the first IPA tank connected to the fluid line circulation circuit through a first IPA line and a second IPA tank connected to the fluid line circulation circuit through a second IPA a second drain selectively connected to the first and second IPA tanks, a first deionized water line selectively connectable to a deionized water source and to the fluid line circulation circuit, and a vacuum pump selectively connectable to the fluid line circulation circuit through a vacuum selection valve, wherein the fluid line circulation circuit is selectively configurable to flow water, nitrogen and IPA through a unit under test.

Systems and methods for safe on-line pigging decoking of a coker furnace tubes and which also permits on-line spalling operations.

A method includes forming a film of a compound on an inner wall of a gas supply line by polymerization of a first compound and a second compound by controlling a temperature of the gas supply line to a first temperature at which the first compound and the second compound are polymerized in a state where a first gas containing the first compound and a second gas containing the second compound are supplied to the gas supply line, and removing the film by controlling the temperature of the gas supply line to a second temperature at which the film is depolymerized after predetermined processing is performed on a target object in a processing chamber by a processing gas supplied into the processing chamber through the gas supply line having the film. The first compound is isocyanate. The second compound is amine or a compound having a hydroxyl group.

Provided is a fluid treatment system, including: a plurality of fluid channel devices arranged in series along a regular channel; a plurality of flow control valves each adjusting the flow rate of a treatment target fluid flowing into each of the plurality of fluid channel devices; a flow control valve provided on the upstream side of the plurality of fluid channel device and operable to change the flow rate of the treatment target fluid flowing into each of the plurality of fluid channel device; a bypass channel allowing the treatment target fluid to flow so as to bypass the fluid channel device in which abnormality has occurred, and a plurality of bypass selector valves selectable between a state of allowing the flow of the treatment target fluid in the bypass channel and a state of blocking the flow.
