  • Patent number: 10697263
    Abstract: A centering device on a cutting device using an ultrahigh pressure (UHP) hose carrying UHP fluid is designed to be inserted into a pipe or tube and cut the same from the inside out. In one example, the cutting device is for insertion into a wellbore for cutting the casing of the wellbore from within the wellbore with a revolvable UHP hose. The cutting head which effectuates the cut may be centered by the centering device that is generally conical in shape such that a portion of the centering device remains exterior to the pipe or tube as the UHP revolves during the cutting action.

  • Patent number: 7430812
    Abstract: Disclosed is a device used to set twist angles. The device include a set plate which is supported at one end and a protractor plate at a second end. The hose is placed in position atop the two supports and the hose placed on top of the supports with couplers at each end. The user then clamps the first coupler in a horizontal position pointing toward one of two sides of the set plate. This is used as a reference from which a twist angle may be set at the other side of the tool. The other side of the tool includes a protractor in such a way that the elbow can be rotated in position relative to one of two scales. These two scales are color coded such that for acute angles, the user will know to point the first end horizontally in the red (?) direction and for obtuse angles the user will point the coupler in the blue direction. Depending on which color the user selects will match it up and the elbow twist angles will be properly set. The hose is easily unclamped from the device and crimped.

  • Patent number: 7421461
    Abstract: A pipe reference and calculating device pipe reference and calculating device includes a housing that can be held in a hand of a user. A processor is contained within the housing. A keypad is on the housing and is electrically connected to the processor. The keypad operates a plurality of switches, each switch controlling a circuit to produce an input signal to the processor for a desired function. A display screen and a memory device are disposed in the housing and are electrically connected to the processor. Software is stored in the memory device. The software causes the processor access data from a database of pipe reference information and data, and formulas, perform pipefitting calculations with data accessed from the database, perform calculations on data input from the keypad, and perform pipefitting and geometric calculations using graphical images with labeled variables.

  • Patent number: 7350311
    Abstract: A universal reusable template for cutting ends of cylindrical objects such as pipes, in preparation for joining the cylindrical objects to other cylindrical bodies. The template is formed as a flat flexible bendable sheet with magnetic properties allowing the sheet to be temporarily secured on a metal pipe. The front face of the sheet has reference indicia corresponding to contour lines of a desired cut to be made in the end of the cylindrical body. The cut lines represent most conventional types and sizes of lateral-type cuts, eccentric cuts and saddle-type cuts, with pipe diameters ranging from about 3? to about 24?.

  • Patent number: RE45010
    Abstract: A piping alignment tool suitable for locating where an extension of an existing pipe must pass through obstructions such as walls. The tool has a tubular shape with oppositely disposed ends. Each end is formed to have multiple coaxial sets of different-sized pipe threads that allow the tool to be threaded onto a pipe having one of the pipe thread sizes formed on the tool. The tool is also equipped to generate light beams from each end, so that the light beam can be emitted from an end of the tool opposite a pipe onto which the tool has been threaded. By threading the tool onto a pipe and emitting a light beam from the end of the tool opposite the pipe, the location of an obstruction beyond the existing pipe is illuminated by the emitted light beam.
