Abstract: A flanged sealing ring which is used to seal a pipe connection is produced from a material having a metal fraction distributed substantially homogeneously in the flanged sealing ring. The flanged sealing ring can be used in a device for detecting components of a flanged sealing ring in a pipeline system that includes a plurality of pipes, at least two of which are held against each other at a flange in such a way that sealing is effected by a flanged sealing ring. Using a metal detector and a gate for removing a metal-containing substance from the pipeline, which gate is arranged behind the metal detector in the conveying direction, the flanged sealing ring can then be detected, and therefore, when components of the flanged sealing ring detach, detection can be performed at the metal detector and discharging can be performed at the gate.

Abstract: A pipe coupling apparatus adapted to allow for the connection of older, common sewer or drain pipe made of concrete, clay or the like to that of the newer style polymers such as ABS, CPCV, PVC and the like. It accomplishes this through a novel connection method that eliminates having to cut off the bell end of the older sewer or drain pipe and provides for a method of stabilizing the alignment of the two connected pipes. The apparatus incorporates a pipe coupling and a flexible polymer transition sleeve, and depending on the dimensions of the pipes involved, may require an optional spacer seal ring. The assembly time is greatly reduced over the prior art methodologies and the coupled pipes are less likely to leak. It is available in both eccentric and concentric configurations.

Abstract: A process for treating a pin having an external threaded portion and a box having an internal threaded portion wherein the process provides a threadable joint having a high galling resistance. One embodiment of the present invention includes applying a lubricant on the threaded portion of at least one of the pin and box. The threadable joint is made up by threadably engaging the threaded portions of the pin and box to a recommended torque according to the American Petroleum Institute and then breaking out the threaded joint. The making up and breaking out step with lubricant applied on the threaded portion of at least one of the pin and box is performed a plurality of times. One of the threaded portions of the pin and box is then case hardened. The threadable joint made from this process is highly resistant to galling without the requirement of any lubricant.

Abstract: The load flanks in the male threaded portion of the pin and the load flanks in the female threaded portion of the box have a flank angle of less than 0 degrees. The female threaded portion is divided into, in order from near the seal surface, an incomplete thread section and a complete thread section. In the female threaded portion, over the entire area including the two thread sections, roots collectively define a single tapered periphery. The incomplete thread section has a length of at least three times the thread pitch and has a thread height lower than a thread height of the complete thread section. The shoulder surfaces are in contact with each other, the seal surfaces are in contact with each other, and in the incomplete thread section, clearances are provided between the roots of the male threaded portion and the crests of the female threaded portion.

Abstract: An insulating collar for a gap sub assembly for electromagnetic (EM) telemetry used in downhole drilling is disclosed. The gap sub assembly comprises a female member comprising a female mating section and a male member comprising a male mating section and a gap section. The male mating section is matingly received within the female mating section and electrically isolated therefrom. The insulating collar is positioned on the gap section. The collar is made up of a framework with a plurality of discrete bodies spaced about the framework and a portion of each of the discrete bodies protrudes above the framework. Either the framework or the discrete bodies are made of an electrical insulator material to electrically isolate one end of the collar from the other end of the collar. The collar therefore electrically isolates the male member from the female member and the male member, female member and insulating collar function as the “gap sub” for EM telemetry.
