Surface treatment of a tubular surface defining an axis extending from a first surface end to a second surface end includes partially surrounding the tubular surface, at a first position, with a first set of treating units, with the treating units arranged in a first arcuate array. Furthermore, each treating unit is configured to include a plurality of first applicator heads. In some examples, a position of each of the plurality of first applicator heads is determined relative to the tubular surface. The first set of treating units is moved from the first position towards a second position. In one non-limiting example, each of the plurality of first applicator heads is independently controlled to selectively apply a first treatment as the first set of treating units moves from the first position towards the second position.

In one non-limiting example, the method further includes independently controlling each of the plurality of first applicator heads to selectively apply a first treatment as the first set of treating units moves from the first position towards the second position.

A cleaning apparatus for pharmaceutical containers, comprising means for feeding containers into and means for discharging containers from the cleaning apparatus, a transport apparatus for transporting containers within the cleaning apparatus, at least one holder for holding containers during a cleaning process, and one or more cleaning stations. Each holder holds a container such that a longitudinal axis of the container extends substantially in a vertical direction. Each cleaning station comprises at least one substantially cylindrically formed annular nozzle configured to completely surround a container during the cleaning process. Each cleaning station is provided on its inner side with a first row of outlet openings disposed circumferentially in a first vertical position, and is configured to discharge a cleaning medium substantially identically inwardly and downwardly at an angle to a horizontal axis and at an angle to a radial direction to form a cyclone of cleaning medium.

A system for coating profiles comprises several treatment stations for treating the profiles, including at least one coating station for coating the profiles, the station being equipped with spray guns for dispensing the electrostatically charged powder coating. The system further comprises first detection means for detecting first data concerning the dimensions and shape of said profiles, first storage media for storing second data concerning said powder coating, which shall be used for coating said profiles, second storage media for storing third data concerning a set of sample profiles, and comparison means for comparing said first, second and third data so as to generate commands adapted to vary the operating parameters for said guns.

An applicator machine and a process for heating and coating a section of pipeline. The applicator machine includes a frame configured to rotate about a section of pipeline to be heated and coated, rotating means operable to rotate the frame, and coating material applicators induction coils and radiant heaters mounted on the frame and rotatable therewith. The induction coil is configured to heat a section of pipeline adjacent to the induction coil to a coating material application temperature. The radiant heaters are configured to heat factory-applied coatings. Each coating material applicator sprays coating material through an aperture in a respective induction coil. The applicator includes an enclosure configured to surround a section of pipeline and provision for evacuating and collecting waste coating material. The coating material applicator may be configured to spray powder coating material, such as fusion bonded epoxy powder material and/or chemically modified polypropylene powder material.

A surface treatment assembly for treating a contoured surface includes an adjustable base having at least a first contour shape and a second contour shape. The surface treatment assembly further includes a plurality of applicator heads that are coupled to the adjustable base. Moreover, each applicator head is configured to apply a surface treatment to the contoured surface. Furthermore, the surface treatment assembly includes an actuator which is operatively coupled to the adjustable base and the actuator is configured to manipulate the adjustable base between the first contour shape and the second contour shape.

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.

The present invention is for coating a surface area of a gap in the coating of a pipeline, said surface area having a length along the central longitudinal axis of the pipeline and a width of at least part of the circumference of the pipeline. The device according to the invention comprises: a frame; a spray nozzle support element supporting a number of spray nozzles; a linear motion mechanism configured for translating the spray nozzle support element relative to the frame and parallel to a longitudinal axis of the frame; and support members configured for arranging the frame stationary relative to the pipeline with said longitudinal axis of said frame coinciding with the central longitudinal axis of the pipeline.
