  • Patent number: 11965611
    Abstract: Provided is a threaded pipe having a pin member connecting to a box member. The pin member contains wedge-shaped pin threads that extends in a helical direction around the outside surface of its pipe end. The pin member is tapered to result in an increasing diameter of the pin threads away from the front end of its pipe. The box member contains a wedge-shaped box thread that stretches in a helical direction around the inside surface of its pipe end. The box member is tapered to result in a decreasing diameter of the box threads away from the front end of its pipe. The pin crest of the pin member increases in width along the pin thread and the box root of the box thread decreases in width along the box thread. When assembled together, the pin thread crest increases in width at a different rate than the box thread root increase in width.

  • Patent number: 11453568
    Abstract: A flexible pipe containment sled includes a platform and a first sled portion coupled to a bottom surface of the platform. The first sled portion is disposed at a first side of the platform. The sled also includes a second sled portion coupled to the bottom surface of the platform. The second sled portion is disposed at a second side of the platform opposite to the first side of the platform. The sled also includes a passage formed between the first and second sled portions. The passage is configured to allow a flexible pipe to pass through the passage while the flexible pipe containment sled is placed on a surface.
