20140137662 | ACOUSTIC FLOW RATE METER - Acoustic flow rate meter for the noninvasive determination of the flow or the flow rate in electrically conductive objects through which media flow, in particular pipes or pipelines, having an excitation transducer for generating at least one ultrasonic wave in the object, which is coupled into the medium as a longitudinal wave on an inner side of the object oriented toward the medium, and having a receiving transducer for the detection of an ultrasonic signal in the object, wherein the ultrasonic signal at least partially results due to the longitudinal wave, wherein the excitation transducer is implemented as a high-frequency induction coil, while omitting an acoustic coupling of the excitation transducer with the surface of the object, to generate a varying magnetic field in a surface-proximal region of the object, which is metallic in particular, and the ultrasonic wave is generated by interaction of the varying magnetic field with a static or quasi-static magnetic field in this region. | 05-22-2014 |
20130292936 | Pipe Arrangement and Process - Pipe arrangement comprising two pipes and a sleeve ( | 11-07-2013 |
20110260853 | Covering Arrangement for a Pipe, and Pipe Having such a Covering Arrangement - 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. | 10-27-2011 |
20110260852 | Security Device and System for Monitoring Pipes - 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 processer designed for analyzing the signals and for out-putting an alarm signal. | 10-27-2011 |

20110259589 | Maintenance Device and Method for Producing a Maintenance Access - The invention relates to a maintenance device for maintaining an elongated and in particular tubular hollow body ( | 10-27-2011 |
20110094613 | Pipe for Transporting a Medium and Method for Manufacturing a Pipeline - A pipeline has a first pipe and a second pipe welded together by a weld seam, wherein the first and second pipes each have an inner side with a lining section of plastic material for protecting an inner side of the pipeline. The lining sections end at a spacing from the weld seam. The lining section of the first pipe abuts the lining section of the second pipe such that by an undercut provided on at least one of the lining sections a fill space is formed in a circumferential direction of the pipeline. | 04-28-2011 |
20100253475 | Device and method for monitoring a maintenance unit - The invention relates to a method for monitoring a maintenance unit moving inside a pipeline, a state data signal generated by a first receiving and transmission unit due to a maintenance unit passing by being transmitted to at least one further receiving and transmission unit that is disposed at a distance along or in a pipeline, characterized in that the state data signal is provided with exact localization information by the first receiving and transmission unit, is routed via at least one further receiving and transmission unit in the direction of an interface device, and is supplied there to a SCADA system for analyzing the information that can be retrieved from the state data signal in quasi-real-time. | 10-07-2010 |
20100162503 | Cleaning Pig - A cleaning pig for a pipeline for long-distance transportation of a fluid material is advanced in the pipeline in a travel direction by the fluid material transported in the pipeline. The cleaning pig has a pig body and two collars connected to the pig body and spaced apart from one another. The pig body and the collars fill a pipe cross-section of the pipeline. An intermediate space is delimited between the two collars. A pressure opening is arranged at a trail end of the pig body in the travel direction. A pressure conduit connects the pressure opening to the intermediate space. A suction device is arranged in the intermediate space. A suction outlet is connected by a suction conduit to the suction device. The pressure conduit is connected to at least one jet opening directed with a jet action against an inner wall of the pipeline. | 07-01-2010 |
20090293622 | Device and Method for Nondestructive Testing of Pipelines - 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. | 12-03-2009 |
