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.
Claims12
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 at least a portion of the collar comprises a thickness that varies as viewed along a plane extending axially along a diameter of the collar, wherein the collar comprises a fiber reinforced composite comprising fibers and resin having fibers oriented along a hoop direction and 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 over the portion of the tube, wherein at least a portion of the collar comprises a thickness that varies as viewed along a plane extending axially along a diameter of the collar, wherein the collar comprises a fiber reinforced composite comprising fibers and resin having fibers oriented along a hoop direction and fibers oriented generally transverse to the hoop direction.
