    Abstract: A measuring arrangement, comprising: a pipe with a pipe axis and an ultrasonic, flow measuring device. The ultrasonic, flow measuring device has a sensor unit, which is fixed in a hole in the pipe, which hole is introduced essentially perpendicularly to the pipe axis into the pipe wall. The sensor unit has a rail or a rod with a longitudinal axis. The rail or the rod bears at least two ultrasonic transducers, which define a signal path, wherein the signal path extends parallel to or on the longitudinal axis of the rail or of the rod, and wherein the signal path is tilted from a perpendicular connecting line between the center point of the hole and the pipe axis. In addition, an ultrasonic, flow measuring device is noted.

  • Patent number: 9039330
    Abstract: A boring shield apparatus for attachment to a boring machine/jack for installing pipe sections underground is provided by this invention. Such invention comprises drill heads and a screw auger that rotate with respect to a non-rotating exterior housing. When the boring shield is operatively connected to the boring machine jack and moved forward into contact with the earth along the desired underground pathway for the pipeline, dirt is excavated by means of the rotating drill head and transferred inside a self-contained screw auger whereupon it is pushed safely away from the boring shield and boring machine. This boring shield apparatus pivots with respect to itself for enhanced steering capacity. It accommodates pipelines of larger diameter and length and rough exterior surface.

  • Patent number: 7398797
    Abstract: There is provided a pipe lining method wherein a lateral pipe lining material and a main pipe lining material are securely joined. After a lateral pipe has been lined, a start liner is applied to the main pipe and a main pipe lining material is then inserted. A heating wire for melting the start liner is mounted on a surface of a flange of the lateral pipe lining material during or after lining of the lateral pipe. While the main pipe is being lined, the heating wire is heated to melt the start liner existing between the flange of the lateral pipe lining material and the main pipe lining material. When the resin in the main pipe lining material is cured, the main pipe lining material and flange of the lateral pipe lining material are integrated. This allows the lateral pipe lining material and main pipe lining material to be reliably joined.
