Abstract:
A lateral applicator kit for a pipe has a first and a second application unit that are configured to apply a primer material or other substance to the exterior and interior lateral walls of a pipe. The first unit receives primer through a first supply engagement feature, which is in fluid communication with a first material reservoir internal to the first application unit and further in fluid communication with an application receptacle configured to receive, and apply primer to, the exterior lateral surface of a pipe. The application receptacle has at least one first material applicator connected across at least one first application opening through which primer is absorbed and distributed to the pipe. The application receptacle has a tapered, flexible applicator wall for adaptably accommodating a range of pipe diameters. The second unit is similarly but inversely configured to adaptably apply primer to the interior surface of a fitting.
Abstract:
A method of lining an inner surface of a tubular with a polymer, includes positioning a polymer injecting head within the tubular, forming an annular space between the injecting head and an inner surface of the tubular, injecting polymer through the injecting head into the annular space, and moving the polymer injecting head longitudinally relative to the tubular while injecting polymer.
Abstract:
A coating apparatus is disclosed for applying an activated coating onto an internal surface of a conduit, the coating being activated by mixing at least a first and a second component. The apparatus includes a high-pressure mix gun for mixing the at least first and second components such that the activated coating is generated. A rotary atomizer is operatively connected to and cooperates with the high pressure mix gun for receiving the activated coating from the high pressure mix gun. The rotary atomizer cooperates with the activated coating such that the activated coating is atomized so that application of the atomized activated coating onto the internal surface of the conduit is permitted.
Abstract:
The coating device has a rotatable spindle which has fastening mechanisms for fastening a rotation axle to the spindle. Protrusions are radially protruding from the spindle for spreading the coating substance on the inner surface of a pipe. The protrusions have limiters that limit the coating substance to be spread to the desired layer thickness. The method comprises the steps of bringing, to the pipe to be treated, the coating device fastened to a rotation axle with the pipe, a feeding hose of the coating substance and a camera. The coating substance is fed along the feeding hose to a vicinity of the coating device. The coating substance is spread to an inner surface of the pipe by rotating the coating device and by moving the coating device in a longitudinal direction of the pipe.
Abstract:
A slip molding apparatus (10) for lining a pipe (12) includes a dispense head (20) adapted to engage an interior surface (14) of a pipe (12) and to dispense a lining material, a slip mold (38) pulled by the dispense head (20) and having a leading end (42) and a trailing end (44), wherein the trailing end (44) has a greater diameter than a diameter of the leading end (42), at least one camera (58) disposed on the dispense head (20) to provide a view of the interior surface (14) of the pipe (12), a guide (46) connected to the dispense head (20) and the slip mold (38) for guiding the lining material dispensed by the dispense head (20) about the slip mold (38), and a movable diverter (52) on the slip mold (38) cooperating with the guide (46) to divert a flow of lining material dispensed by the dispense head (20) about the slip mold (38).
Abstract:
The coating device that has a rotatable spindle which has fastening mechanisms for fastening a rotation axle to the spindle. Protrusions are radially protruding from the spindle for spreading the coating substance on the inner surface of a pipe. The protrusions (12b) are flexible and plate-like strips that twist around the axis of their longest side so that the cross-sectional area of the protrusion, in the direction of the rotation axle of the spindle, is at its smallest at the outermost end. The protrusions have limiters that limit the coating substance to be spread to the desired layer thickness.
Abstract:
A coating system to coat the interior of a pipeline section using a UV curable coating and an internally pressurized UV foil that assists in suspending and distributing coatings during UV curing. The UV foil may be installed through the length of the pipeline section using an inversion system driven by pressurized air. The system includes a coating delivery system for distributing the coating along the interior of the pipe. The system includes a UV light source capable of delivery sufficient UV light to cure the coating. The UV light source may include a light train having a plurality of UV light sources, such as UV light emitting diodes, carried by a motorized trolley. The coating system includes an inlet adapter that facilitates inversion and pressurization of the UV foil, as well as introduction of the UV light source into the interior of the pressurized UV foil.
Abstract:
The method to radially displace liquid liner inside a pipe includes the step of flowing the liner around a distributive body placed within a pipe gas stream. As the gas streams past the distributive body, the liner coats the pipe homogeneously from top to bottom.
Abstract:
Systems and methods for reinforcing a pipe. A robot is adapted for rotating in a pipe to apply resin and/or fiber to an inner surface of a pipe in a generally helical pattern. Application of resin and/or fiber to the pipe may be actively adjusted to achieve desired application. A rate at which the robot moves along the pipe per revolution of the robot can be may be adjustable. A rate at which fiber is advanced toward the inner surface of the pipe may be adjustable for application of the fiber to the inner surface of the pipe in a generally non-tensioned state.
Abstract:
The present invention relates to coating of tubes, and more particularly to a system and method for coating and/or renovating deteriorated or pitted tubes to extend tube life and enhance performance. Using this system and method a thin coating is applied to the interior of a tube such that the coating is uniform in thickness and covers all regions of the tube. The coating material may be selected to minimize changes in heat transfer or may be selected to provide for the change in working fluid within the tube such that the working fluid does not negatively interact with the tube material.
