Abstract
A hose assembly includes a metal hose, an end connection having a distal end defining a fluid connector and a proximal end defining a tube stub received in a distal end portion of the hose, and a weld collar surrounding the distal end portion of the hose and the tube stub of the end connection, with the weld collar, the hose distal end portion, and the tube stub being welded together at a welding zone proximal to a distal edge of the metal hose.
Claims20
A hose assembly comprising:
- a metal hose;
- an end connection having a distal end defining a fluid connector and a proximal end defining a tube stub received in a distal end portion of the hose;
- and
- a weld collar surrounding the distal end portion of the hose and the tube stub of the end connection, with the weld collar, the hose distal end portion, and the tube stub being welded together at a welding zone proximal to a distal edge of the metal hose.
1 more element
A method of making a hose assembly, the method comprising:
- inserting a distal end portion of a metal hose into a proximal end of a weld collar;
- inserting a proximal end tube stub of an end connection into the distal end portion of the metal hose, such that the distal end portion of the metal hose is radially disposed between the weld collar and the tube stub;
- and
- welding the weld collar, the hose distal end portion, and the tube stub together at a welding zone proximal to a distal edge of the metal hose.
1 more element
A method of making a weld collar for a hose end, the method comprising:
- providing a tube section;
- using a crimping tool, crimping the tube section to form a radially inward extending distal end portion defining an internal stepped portion, a tapered proximal end portion, and an intermediate portion extending axially and radially between the proximal end portion and the distal end portion.
