1. A clamp for requiring a pipe coupling between a first pipe section and a second pipe section through which fluid flows during the repair, comprising:
a first clamp unit extending along a central longitudinal axis of the clamp, the first clamp unit comprising:
a first end, the first end comprising:
a first flange; and
a plurality of first flange holes extending through the first flange;
a second end;
a first body portion extending between the first end and the second end; and
a first window extending through the first body portion in a direction perpendicular to the central longitudinal axis for exposing a first flange of the pipe coupling;
a second clamp unit removably coupled to the first clamp unit and extending along the central longitudinal axis, the second clamp unit comprising:
a first end, the first end comprising:
a second flange; and
a plurality of second flange holes extending through the second flange, and aligned with the plurality of first flange holes of the first clamp unit;
a second end;
a second body portion extending between the first end and the second end; and
a second window extending through the second body portion in a direction perpendicular to the central longitudinal axis for exposing a second flange of the pipe coupling; and
a coupling constructed and arranged to extend through each of the aligned first and second flange holes.
