Abstract
A collar for applying a radial compressive force to an outer surface of a tube and a tube assembly including the collar and the tube.
Claims17
An annular collar for applying a radial compressive force to an outer surface of a tube, said collar comprising:
- a first end axially opposite a second end;
- and
- an inner surface, wherein the collar in cross-section as viewed along a plane extending axially along a diameter of the collar comprises a first section and a second section radially adjacent to the first section, wherein the second section surrounds the first section, wherein the collar comprises a fiber reinforced composite comprising fibers and resin, wherein fibers forming one of the first and second sections are oriented along a hoop direction, and wherein the other of the first and second sections comprises fibers oriented generally transverse to the hoop direction.
A tube assembly comprising:
- a fitting having a first end opposite a second end;
- at least a section of the fitting having an annular outer tapered surface reducing in diameter in a direction axially along an axial direction toward one of said first and second ends;
- a tube having a portion over the annular outer tapered surface, said portion having an outer surface tapering from a larger outer diameter to a smaller outer diameter;
- and
- an annular collar having an inner surface over an outer surface of the portion of the tube, wherein the collar in cross-section as viewed along a plane extending axially along a diameter of the collar comprises a first section and a second section radially adjacent to the first section, wherein the second section surrounds the first section, wherein said collar comprises a fiber reinforced composite material comprising fibers and resin, wherein fibers forming one of the first and second sections are oriented along a hoop direction, and wherein the other of the first and second sections comprises fibers oriented generally transverse to the hoop direction.
