Pipe Coupling Spacer Insert

A coupling system for connecting two tubulars, the coupling system comprising a coupling, a first tubular and a second tubular connected together by the coupling, each tubular having a tubular end within the coupling, the tubular ends spaced-apart from each other, a spacer between the tubular ends and in contact therewith, the spacer comprising at least two parts, the at least two parts movable with respect to each other, wherein each of the at least two parts has a body with a thickness sufficient to protect the tubular ends, wherein there is a space between the tubular ends and the spacer occupies said space, wherein the at least two parts comprise an inner part and an outer part, each of said inner and said outer part having a channel therethrough defined by an inner wall of a part body and said channels providing a smooth surface through the spacer for enhancing flow through the spacer and through the tubulars, and wherein the at least two parts fit together with a friction fit.

A spacer for use in a coupling for coupling together two tubulars, the coupling with a coupling body, the coupling body being generally cylindrical and having a channel therethrough, the coupling body with two spaced-apart ends, each end threaded for threaded mating with a tubular so that the coupling connects the two tubulars, the coupling having an interior wall, the spacer comprising two parts, a first part and a second part, the first part movable with respect to the second part to accommodate a distance within a coupling between spaced-apart ends of two tubulars connected by the coupling.
