Abstract
A gauge for measuring a weld between two abutted pipe sections has a unitary body including a reference edge for abut an outer surface of the pipe sections, a first gauge portion at a prescribed first distance from the reference edge corresponding to a minimum cap height of the weld, and a second gauge portion at a prescribed second distance from the reference edge corresponding to a maximum cap height of the weld. One or both ends of the body includes an end surface and a bevel surface at an obtuse angle to the end surface so as to be arranged to abut a bevel cut end of a pipe section when the end surface abuts the outer side of the pipe section to gauge an inclination of the bevel cut end. A measurement scale with an advance cut line extends along the body opposite from the reference edge.
Claims15
A gauge for use in measuring a weld between two abutted pipe sections, the gauge comprising:
- a unitary body comprising:
- at least one reference edge arranged for abutment along an outer surface of at least one of the pipe sections;
- a first gauge portion in fixed relation to said at least one reference edge and arranged to be located at a prescribed first distance from said at least one reference edge corresponding to a minimum cap height of the weld relative to the outer surface of the pipe sections;
- a second gauge portion in fixed relation to said at least one reference edge and arranged to be located at a prescribed second distance from said at least one reference edge corresponding to a maximum cap height of the weld relative to the outer surface of the pipe sections.
A method of measuring if an external profile of a weld between two abutted pipe sections is between a prescribed minimum cap height and a prescribed maximum cap height, the method comprising:
- providing a gauge comprising a unitary body having at least one reference edge, a first gauge portion in fixed relation to said at least one reference edge at a prescribed first distance from said at least one reference edge corresponding to the prescribed minimum cap height, and a second gauge portion in fixed relation to said at least one reference edge at a prescribed second distance from said at least one reference edge corresponding to the prescribed maximum cap height;
- abutting at least a portion of said at least one reference edge along the outer surface of at least one of the pipe sections such that the first gauge portion is aligned with the weld;
- identifying if the first gauge portion engages the weld;
- abutting at least a portion of said at least one reference edge along the outer surface of at least one of the pipe sections such that the second gauge portion is aligned with the weld;
- and
- identifying if the second gauge portion engages the weld.
