An Tube Spray Gun for coating an elongated member comprising a handle, a flow trigger, at least one positioner engaging the member and adapted to maintain a spray tip in a desired position relative to the member, a mounting means for releasably engaging the spray tip assembly around the member, a coating supply fluidly connected to the spray tip and a flow activated by the trigger and a spray tip assembly calibrated to provide complete radial coverage of the member, whereby an user engages the positioner placing the apparatus around the member and activates the flow trigger while moving the apparatus along the member to coat the entire radial surface of the member with a single pass.

A system for coating a heat transfer tube for a condenser is disclosed. The system simplifies a process of coating the heat transfer tube, and is able to uniformly coat a plurality of heat transfer tubes. In addition, the system is economically feasible in that coating solution can be reused by collecting and circulating it. Due to super-hydrophobic coating, the size of a droplet condensed on the surfaces of the heat transfer tubes coated by the system can be reduced, and a condensation heat transfer coefficient can be increased.

A system for applying a fiber matrix on a tubular member is provided. A mandrel, configured for atraumatic placement within the tubular member, is included. Methods for atraumatic placement of a mandrel into a tubular member are also provided.

A coating apparatus for coating a perimeter surface of a pipeline. A frame selectively mounts a sprayer on the pipeline. The sprayer can spray fluid along a flow path in a spraying mode and preparation mode. In the preparation mode, a fluid diverter moves into the flow path to divert the fluid delivered from the sprayer away from the pipeline. In the spraying mode, the fluid diverter moves out of the flow path to permit the sprayer to coat the perimeter surface of the pipeline with a curable liquid. A vacuum system can draw a vacuum through the diverter to remove the fluid the sprayer sprays in the preparation mode. The flow path can be located in a spray shroud. The diverter can fluidly couple the vacuum system to the shroud interior in the spraying mode to remove overspray.

A system for coating a non-rotating pipe work piece including: valves, flow lines, and a mixing block for receiving a first and a second component material each delivered at a pressure, flow measurement devices to measure the flows of the components, a static mixer in fluid communication with the mixing block for receiving the combined components, a C-shaped plate member arranged around the work piece, a drive mechanism to oscillate a partial rotation of the C-shaped member about the work piece with the rate of oscillations controlled by a logic controller, at least two spray guns disposed on the C-shaped member to spray towards the outside surface of the work piece, a drive mechanism to traverse the at least two spray guns longitudinally with the rate of traverse controlled by a logic controller; and the logic controller(s) programmed to control based on a number of input and measured parameters.

The present disclosure provides an airplane ground deicing installation that minimizes the impact of deicing operations on the airport during icing conditions. The installation does not require alteration of a normal taxi pattern and can be performed as quickly as the average separation time between take-offs. The installation allows modification of its shape to adapt to the contour of almost all types of commercial passengers airplanes operating from major airports, and simultaneously deices large surfaces of the airplane. Deicing and anti-icing fluids are applied to airplane surfaces from nozzles positioned in close proximity to the airplane's surface. Speed and adaptability to different types of airplanes, combined with a design that allows rapid relocation of the installation, are key features that make it possible to place the installation on the taxiway, close to the head of the runway it serves, such that the taxi pattern and the separation in between takeoffs are not altered as compared to the normal operations of the airport.

The invention relates to apparatuses for treating the outside surface of cylindrical articles, and can be used for applying liquid substances to the surface of such articles. The apparatus for applying a coating additionally comprises a roller rotation actuator, a carriage and at least two arcuate brackets movably joined to the carriage. The rollers are designed to be capable of bending easily in any direction and have high torsional stiffness and low bending stiffness. One end of each roller is rotatably fastened to the carriage and is connected by a spindle to the rotation actuator. The other end of each roller is rotatably fastened to the free end of an arcuate bracket. The brackets are mounted on the carriage with a distance therebetween sufficient to accommodate the cross-section of the article to be treated. The brackets are capable of rotating towards one another in a mutually perpendicular manner and of enclosing the cross-section of the cylindrical article in a semi-circular manner. The technical result of the invention is increased efficiency, a simplified design, reduced dimensions and greater functional capabilities.

A pipe conditioning tool comprising a drive unit to move the tool along a pipe and a work head rotatable about an axis of the pipe to condition a surface of the pipe, the drive unit includes a frame extending to opposite sides of the pipe, the frame having legs extending radially beyond the work head to provide support for the tool upon removal from said pipe.

An apparatus for powder coating a welded pipe joint includes a coating head having a powder chamber and at least one vacuum chamber. The coating head is mounted to a carriage operable to circumferentially traverse a pipe workpiece. The powder chamber has at least one inlet for receiving an air/powder suspension, and at least one outlet for delivering the air/powder suspension to a pre-heated weld zone of the pipe, such that the suspension fuses to and coats the weld zone. The vacuum chamber has at least one powder inlet for receiving excess air/powder suspension from the weld zone, and is connectable to a source of vacuum for exhausting the excess air/powder suspension from the weld zone. The coating thickness in the weld zone can be controlled by coordinated regulation of the air/powder flow rate into the powder chamber and the exhaust flow rate from the vacuum chamber.
