Method of forming a flared-end pipe with a reduced resistance bead seal and method of use

A method of sealingly joining two members together comprising the steps of:

• forming a first mounting surface on a first member:
• forming a second mounting surface on a second member by axially pressing a tool into the second member to form exterior and interior parallel conical surfaces extending angularly from the axial extent of the second member;
• simultaneously with the step of forming the second mounting surface, extruding an annular reduced resistance bead by the axial pressing of the tool as a continuous, one-piece extension from a plane defined by the second mounting surface of the second member;
• and
• joining the first and second members to bring the reduced resistance bead into complete annular, sealing engagement with the first mounting surface of the first member.

A method of forming a flared end on a fluid conduit comprising the steps of:

• forming a first end of a conduit radially outward from an axial extent of the conduit with an end extending radially inward by axially pressing a first tool into the first end of the conduit;
• bending a portion of the first end of the conduit inward on itself by axially pressing a second tool into the first end of the conduit to form exterior and inner substantially parallel flanges, an exterior conical surface formed on the outer flange and an inner conical surface formed on the inner flange;
• and
• simultaneously with the bending of the flared first end of the conduit extruding an annular reduced resistance bead having a sidewall terminating in an outer end by the axial pressing of the second tool as a continuous, one-piece, radially inward projecting extension from a plane defined by the interior conical surface.

The method of forming a flared end on a fluid conduit comprising the steps of:

• flaring a first end of a conduit radially outward from an axial extent of the conduit by axially pressing a tool into the first end of the conduit to form exterior and interior parallel conical surfaces on the first end of the conduit, both disposed at a predetermined angle from the axial extent of the conduit;
• the step of flaring the first end further including bending a portion of the flared first end of the conduit inward on itself to form outer and inner substantially parallel flanges, the exterior conical surface formed on the outer flange and the inner conical surface formed on the inner flange;
• and
• simultaneously with the flaring of the first end of the conduit, extruding an annular reduced resistance bead having a sidewall terminating in an outer end, the bead formed as a continuous, one-piece, radially inward projecting extension from a plane defined by the interior conical surface.
