Abstract
A tool for determining the perpendicular of the face of a pipe flange relative to the outside diameter of the pipe to which the flange is being attached. The tool being a 90 degree framing square with a lateral or oblique leg portion. The lateral or oblique leg allows the square to be placed on edge with a first leg of the square parallel and in contact with the face of a pipe flange and a second leg at 90 degrees to the first leg extending beyond the pipe flange parallel to and in contact with the outer diameter of the pipe to be joined to the flange. Indicia is provided inscribed on the face of the squaring tool adjacent the contact edges to provide quick reference to the flange size and for use in various other construction layout measurements.
Claims5
A pipe flange square comprising a flat, framing square having an elongated vertical and horizontal leg the horizontal leg positioned 90 degrees relative to the vertical leg, the horizontal leg having an oblique portion therein for offsetting a first portion of the horizontal leg from a second portion of the horizontal leg.
A method for determining the perpendicular of the face of a pipe flange relative to the outside diameter of a pipe being welded thereto comprising the steps of
- a) clamping a pipe flange having a welding neck in close proximity to a squared pipe end prepared for welding;
- b) providing a flat framing square having a vertical and horizontal leg, the horizontal leg being positioned 90 degrees relative to the vertical leg, the horizontal leg having first and second portions separated by an oblique portion, said second portion being offset from said first portion;
- c) determining the perpendicular of the flange face relative to the outside diameter of the adjoining pipe by placing the framing square on edge in a manner whereby the vertical leg is parallel to and in contact with at least two opposing diametrical points located on said flange face;
- d) adjusting said flange relative to the adjoining pipe until linear contact is achieved between the pipe and the second offset portion of the framing square;
- and
- e) moving the framing square circumfrentially around the flange face and repeating step d) until the flange face is perpendicular relative to the outer diameter of the pipe.

- and
- e) moving the framing square rotationally around the flange face and repeating step d) until the flange face is perpendicular relative to the outer diameter of the pipe.
