A method of cleaning an aspiration tube in a specimen measuring apparatus includes: moving the aspiration tube while discharging a cleaning liquid onto an outer side surface of the aspiration tube; stopping the aspiration tube in a state where a tip of the aspiration tube or a droplet attached to the tip contacts a surface of a flow of the cleaning liquid; and moving the stopped aspiration tube in a direction away from the surface of the flow of the cleaning liquid.

A diatomaceous earth filter cleaner for cleaning flex tubes attached to a tube sheet of a diatomaceous earth filter. The diatomaceous earth filter cleaner has a hollow tube, a blast jet housing, an inner diameter scrub brush, and a fitting at an end of the hollow tube for coupling a hose connected to a water supply. The hollow tube of the diatomaceous earth filter cleaner has a length with a first end and a second end for receiving a flex tube. The blast jet housing is attached to the first end of the hollow tube and comprises an angled lip and a restricted orifice formed by an inner circumference of the blast jet housing for receiving a flex tube. The inner diameter scrub brush is received within the inner circumference of the blast jet housing and has an orifice for cleaning an outer circumference of the flex tube.

A method and system for removing hydrocarbon deposits from a heat exchanger tube bundle using an organic solvent. After contact with a heat exchanger tube bundle, the contaminated organic solvent may be treated to remove solids, base waters, and/or suspended hydrocarbons, and then again contacted with a heat exchanger tube bundle for the removal of hydrocarbon deposits. This allows for the removal of hydrocarbon deposits from a heat exchanger tube bundle in an efficient and environmentally friendly manner. The treatment of the heat exchanger tube bundle is also preferably performed using a method and system by which, through contact of the heat exchanger tube bundle with an organic solvent, a large percentage of hydrocarbon deposits are removed from the heat exchanger tube bundle in a short period of time.

Embodiments relate to marine streamer cleaning. An embodiment provides a streamer cleaning apparatus comprising: a housing comprising an inlet configured to receive a streamer and an outlet configured to dispatch the streamer; and scraper lamellas coupled to the housing, wherein the scraper lamellas are arranged to form an opening to receive the streamer. Methods of cleaning a streamer and streamer cleaning systems are also provided.

The invention provides a water treatment apparatus and method of use. The apparatus comprises an inlet configured to be connected to a source of liquid to be treated, and at least one liquid treatment vessel arranged to expose liquid in the vessel to ultraviolet radiation in an advanced oxidation process reaction. A source of ultraviolet radiation comprises a longitudinal axis oriented substantially parallel to a direction of flow of liquid past the source. A boundary surface between the source and a liquid to be treated is provided with one or more cleaning elements arranged longitudinally on the boundary surface. The cleaning elements and the boundary surface are arranged to be rotationally moveable relative to one another around the longitudinal axis of the source.

A mobile pipe rack workstation for inspecting and repairing pipe materials, a “Pipe Station.” By folding the pipe station's load/unload arms, removing any tool's from the tool mount and lowering the gantry by retracting the risers; the pipe station is transportable on public roadways without permitting, escorting, or special signage required for oversized loads.

Methods are disclosed for handling cylindrical tubulars in a process that, in preferred embodiments, also performs cleaning, inspection and other operations on the tubular. The tubular is held stationary while it is rotated. During rotation of the tubular, internal and external cleaning systems, and data acquisition systems, pass up and down the length of the rotating tubular. In preferred embodiments, a first tubular is loaded onto the handling machine, whereupon it is indexed and then rotated. Cleaning, inspection and other operations may be performed during rotation. Once operations are complete, the handling system ejects the first tubular while queuing up a second tubular to be loaded.
