The invention relates to a system (10) for curing and/or inspecting a pipeline lining (30) positioned in a pipeline (20), the pipeline lining (30) comprising an outer plastics material layer and an inner fiber composite layer, the fiber composite layer comprising a plastics material which is to be cured and/or which is at least partially cured. In accordance with the invention, the system (10) comprises at least one high-frequency unit (40) which comprises at least one microwave-generator unit (41) and at least one microwave-transmitting antenna (42) for curing a plastics material which is to be cured, at least the at least one microwave-transmitting antenna (42) being movable in the pipeline (20) by means of a transporting device (60).
A method for curing and/or inspecting a pipeline lining positioned in a pipeline, wherein the pipeline lining comprises an outer plastics material layer and an innermost fibre composite layer, wherein the fibre composite layer comprises a plastics material which is to be cured and/or which is at least partially cured, wherein the method is performed using a system comprising at least one high-frequency unit which comprises at least one microwave-generator unit and at least one microwave-transmitting antenna for curing a plastics material which is to be cured, at least the at least one microwave-transmitting antenna being movable in the pipeline by means of a transporting device, wherein the at least one microwave-generator unit is a solid-state microwave-generator unit and at least parts of the system are introduced into the pipeline in such a way that these parts of the system are surrounded by the pipeline lining, wherein the fibre composite layer is disposed between the at least one microwave-transmitting antenna and the outer plastics material layer, and wherein the plastics material of the fibre composite layer is cured on account of the microwaves emitted by the at least one microwave-transmitting antenna and/or the at least partially cured plastics material is inspected in respect of its degree of cross-linking, and wherein a multi-stage heating process is performed by a plurality of microwave-transmitting antennas, a first stage of the heating process causing a response to be triggered in the plastics material to be cured and a second stage of the heating process being a controlled application of energy to the plastics material following a corresponding detection of a degree of cross-linking of the at least partially cured plastics material.
A system for curing and inspecting a pipeline lining positioned in a pipeline, the pipeline lining comprising an outer plastics material layer and an inner fibre composite layer, the fibre composite layer comprising a plastics material which is to be cured and/or which is at least partially cured, wherein the system includes at least one high-frequency unit which comprises at least two microwave-generator units and at least two microwave-transmitting antenna for curing a plastics material which is to be cured, at least the at least one microwave-transmitting antenna being movable in the pipeline adjacent the fibre composite layer by means of a transportation device including a front unit and a rear unit with the at least one high-frequency unit disposed between the at least one microwave-transmitting antenna and the outer plastics material layer, forming the innermost layer of the pipeline lining, the system further comprises a sensor unit including at least one infrared sensor and optionally one or more of a temperature sensor a pressure sensor a moisture sensor a position sensor a travel measurement sensor, and/or a gyro sensor, wherein the sensor unit senses changes to thermal properties of the plastics material layer and the system adjusts transmissions from at least one microwave-transmitting antenna in response to the changes.
