Method of securing pipe elements end to end
DC CAFCFirst Claim
1. A method of securing facing end portions of pipe elements together in end-to-end relationship, wherein said end portions of said pipe elements have an outer surface of substantially cylindrical profile, said method comprising:
- using a coupling having a plurality of coupling segments attached to one another at both ends surrounding a central space, said coupling segments having arcuate surfaces adapted to interface with the outer surfaces of said pipe elements;
while said segments are attached to one another at said both ends, supporting said segments in spaced relation sufficient to permit insertion of said end portions of said pipe elements into said central space;
while said segments are attached to one another at said both ends and supported in spaced relation, axially inserting said end portions of said pipe elements into said central space; and
drawing said coupling segments towards one another so as to engage said arcuate surfaces with said outer surfaces of said pipe elements.

Abstract
A method of joining pipe elements in end to end relation using mechanical pipe couplings. The couplings have a plurality of segments attached end to end surrounding a central space. The segments have arcuate surfaces adapted to interface with the outer surfaces of the pipe elements. The method includes inserting end portions of the pipe elements into the central space and then drawing the coupling segments toward one another so as to engage the arcuate surfaces of the segments with the outer surfaces of the pipe elements.
