The invention relates to a security device for a cover device of a pipe and/or for a pipe, that can be used for producing pipelines having a series of further pipes welded to each other, wherein the cover device comprises a sleeve covering an inner wall of the pipe, and the security device is designed for generating an alarm signal, wherein the security device comprises a structure-borne sound detection device comprising a structure-borne sound sensor for detecting manipulation of the pipe. The invention further relates to a system for monitoring pipes having a plurality of security devices having a receiving station for receiving the security device signals, preferably repeatable by means of a repeater, and an electronic data processor designed for analyzing the signals and for out-putting an alarm signal.
Covering arrangement for a pipe which can be welded to a series of further pipes to produce pipelines intended, in particular, for transporting gaseous or liquid media, wherein the covering arrangement is designed for sealing at least the pipe edge which is at risk of corrosion, and wherein the covering arrangement comprises an inner cap with an inner sleeve which is designed for abutment against the inside of the pipe and has a covering element which is provided for the purpose of at least partially covering the inner cross section of the pipe which is not covered by the inner sleeve. The invention also relates to a pipe having a corresponding covering arrangement and a system for monitoring pipes having corresponding covering arrangements.
A device for nondestructive testing of pipelines is designed to move along a pipeline and has at least one measuring unit for acquiring measured data of the pipeline, wherein the device is self-propelled and has at least one functional unit rotatable about a central axis of the device for acquiring measured data and/or for driving the device. In a corresponding method for nondestructive testing of pipelines, the device is moved along the pipeline by a functional unit having drive elements and moving helically along a surface of the pipeline to be covered. The functional unit acquires measured data and the drive elements are forced by a magnetic field generated by the functional unit against the surface of the pipeline.
A device for destruction-free testing of ferromagnetic component walls with respect to elongate defects has a sending transducer that excites ultrasound waves in a wall area of a ferromagnetic component wall magnetized in a predetermined direction of magnetization. The ultrasound waves propagate on a path oriented by the sending transducer. A receiving transducer receives the ultrasound waves at a spacing from the sending transducer. The configuration of the sending transducer and a high frequency emitted by the sending transducer, which high frequency is to be determined based on a thickness of the ferromagnetic component wall, are selected so as to effect excitation of horizontal shear waves of higher order. The path orientation is selected at a slant angle to the predetermined direction of magnetization. The receiving transducer is positioned lateral to the path and is oriented toward a predetermined testing area of the wall section in the path.
