Methods and systems comprising a first and a second powder coating apparatus, with each apparatus comprising a tubular barrel having an axial bore extending longitudinally therethrough, are usable for coating an interior surface of a tubular member. Each coating apparatus comprises a conical member connected with the tubular barrel and at least one gas conduit connected to the tubular barrel for communicating gas into the tubular barrel. The at least one gas conduit contains a gas flow control valve connected thereto for controlling the volumetric flow rate of gas through the at least one gas conduit. Each coating apparatus further comprises at least one container for holding a coating material, an inlet conduit for communicating the coating material into the axial bore of the tubular barrel, and a plurality of gas nozzles connected to the tubular barrel for inducing spiraling gas flow through the axial bore of the tubular barrel.

An apparatus and methods for applying an inner coating to a wellbore screen are described. The apparatus comprises a support for the wellbore screen, an elongate injector for injecting coating material into the inner bore of the wellbore screen, and a driver for positioning the elongate injector into the inner bore and moving the elongate injector through the inner bore to introduce coating material to the inner bore. The elongate injector has a supported end, a distal end, and a coating material delivery line extending through the elongate injector from a coating material supply to a port at the distal end.

A system and method for aligning spray guns of a spray system includes a pair of adjustment mechanisms. A laser alignment system employs a target device.

A system for spraying a coating such as lacquer on the internal surface of a can body (2) comprising vacuum chuck gears (42) for each vacuum chuck (16). The vacuum chucks hold the can body as it rotates about a main process turret (10) and to a spray station (32, 34). A ring gear rotates independently of main turret rotation and further gearing connects the ring gear to a vacuum chuck drive motor (11). The spray system provides tight process control and allows flexibility of process revolutions or use of higher machine production speed.

A spray gun mount, and retrofit kit spray gun mount based thereon, and a method of retrofitting, adjusting and spraying based thereon, are structured that the motion of the spray gun occurs about a point of rotation located at the exact nozzle of the spray gun rather than at a location on the gun mount. An arcuate slot may be provided on a fixed mounting plate and extensions (partially threaded screws) pass through the arcuate slot. The extensions in turn are firmly attached to a movable gun mount plate to which the spray gun is affixed. In adjusting the spray gun, all that may be necessary is to loosen a fastener which holds the gun mount plate and gun from rotating relative to the fixed plate, rotating it relative to the fixed plate and fastening it back into place again.

The disclosure provides coating device and coating line for overturned formed fiber container. The coating device for overturned formed fiber container comprises a support configured to support the rim of the container at its upper surface, a pressing block disposed above the support and configured to press the container at its bottom surface; and a spray nozzle configured to spray a solution to the inner wall of the container; wherein, the support is configured to be able to rotate relative to the spray nozzle to drive the container to rotate. With the rotation of the fiber container, the solution sprayed by the spray nozzle and attached to the inner wall of the fiber container will spread evenly to form a coating; and moreover, the solution sprayed by the spray nozzle will be blocked by the inner wall of the fiber container and will not splash around, thus will eliminate the problem of environmental pollution, and there is no need to set a closed chamber around, thus will reduce the occupied area of the equipment.

The present disclosure relates to a process and a system for manufacturing an HSST tyre, as well as the HSST tyre manufactured by the same. The process for manufacturing an HSST tyre includes a cleaning step, a spraying step, and a forced-cooling step. The cleaning step includes an air-drying procedure for evaporating the isopropanol solution on the tyre to be treated with air-drying gases. The forced-cooling step is configured to forcibly cool the tyre to be treated that has been sprayed with the high molecular organic material. By means of accurate design for each step and procedure, the relying on operator's experience is eliminated and thus the performance stability of the HSST tyre is guaranteed. By means of the air-cooling procedure and the forced-cooling step, the time taken to manufacture an HSST tyre is substantially shortened, making it possible to produce the HSST tyre in a large scale.
