a) a set of a first and second semicircular clamp pieces that when joined together by bolts creates a first and second circular clamp piece, wherein a first and second circular clamp creates a four-piece clamping device;

b) wherein each of the four-piece clamps are identical and comprise a semicircular shape, wherein each set of two semicircular clamps bolt together with four bolts to produce a first and second circular clamp piece;

c) wherein each semicircular clamp piece has a projection on each end of the semicircular clamp piece, such that when two semicircular clamp pieces are bolted together to form a circular clamp piece, the projections of each semicircular clamp piece meet to form two larger projections which creates a depression between the two larger projections; and

d) wherein the first and second circular clamp pieces fit together by the projections of the first circular clamp piece fitting into the depression of the second circular clamp piece, and the projections of the second circular clamp piece fitting into the depression of the first circular clamp piece to form a single pipe clamp.
