Abstract

A method for coupling a fitting to a tubing end includes pressing a collar over the outer surface of the tubing until the strain on the collar in the hoop direction is at a predetermined level, or pressing a collar with a predetermined axial load.

Claims (42)

1. 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; 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 substantially all fibers forming one of the first and second sections are axially oriented, and wherein the other of the first and second sections comprises fibers oriented generally transverse to the axial direction, wherein one of the first and second sections has an axial length greater than the axial length of the other of the first and second sections.

2. The tube assembly of claim 1 , wherein substantially all fibers forming the first section are axially oriented, and the second section comprises the fibers oriented generally transverse to the axial direction.

3. The tube assembly of claim 2 , wherein the second section comprises fibers oriented generally perpendicular to the axial direction.

4. The tube assembly of claim 1 , wherein one of said first and second sections is generally triangular in said cross-section defining a collar tapered surface reducing in diameter in the axial direction.

5. The tube assembly of claim 4 , wherein said one of said first and second sections being generally triangular in said cross-section is formed by said substantially all fibers being axially oriented.

6. The tube assembly of claim 4 , wherein the collar tapered surface comprises two tapered surface portions tapered at different angles in cross-section as measured along the plane.

7. The tube assembly of claim 4 , wherein the other of the first and second sections is generally rectangular is cross-section as measured along the plane.

8. The tube assembly of claim 7 , wherein said rectangular section has said axial length that is greater than the axial length of said triangular section.

9. The tube assembly of claim 8 , wherein the collar further comprises a third section radially between the first and second sections.

10. The tube assembly of claim 1 , wherein the first section is formed separately from the second section and wherein the two sections are adhered together after said two sections are formed to form the collar.

11. 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 substantially all fibers forming one of the first and second sections are axially oriented along an axial direction, and wherein the other of the first and second sections comprises fibers oriented generally transverse to the axial direction, wherein one of the first and second sections has an axial length greater than the axial length of other of the first and second sections.

12. The collar of claim 11 , wherein substantially all fibers forming the first section are axially oriented, and the second section comprises fibers oriented generally transverse to the axial direction.

13. The collar of claim 12 , wherein the second section comprises fibers oriented generally perpendicular to the axial direction.

14. The collar of claim 11 , wherein said one of said first and second sections is generally triangular in said cross-section defining a tapered surface reducing in diameter in the axial direction.

15. The collar of claim 14 , wherein said one of said first and second sections being generally triangular in said cross-section is formed by said substantially all fibers being axially oriented.

16. The collar of claim 14 , wherein the tapered surface comprises two tapered surface portions tapering at different angles in cross-section as measured along the axially extending plane.

17. The tube assembly of claim 14 , wherein the other of the first and second sections is generally rectangular is cross-section as measured along the plane.

18. The tube assembly of claim 17 , wherein said rectangular section has said axial length that is greater than the axial length of said triangular section.

19. The collar of claim 11 , wherein the collar further comprises a third section radially between the first and second sections.

20. The collar of claim 11 , wherein the first section is formed separately from the second section and wherein the two sections are adhered together after said two sections are formed to form the collar.

21. 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; 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 in a hoop direction, and wherein the other of the first and second sections comprises fibers oriented generally transverse to the hoop direction.

22. The tube assembly of claim 21 , wherein substantially all fibers forming the second section are oriented in the hoop direction.

23. The tube assembly of claim 21 , wherein one of said first and second sections is generally triangular in said cross-section defining a collar tapered surface reducing in diameter in the axial direction.

24. The tube assembly of claim 23 , wherein said one of said first and second sections being generally triangular in said cross-section is formed by substantially all fibers being axially oriented.

25. The tube assembly of claim 23 , wherein the collar tapered surface comprises two tapered surface portions tapered at different angles in cross-section as measured along the plane.

26. 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 axially oriented along a hoop direction, and wherein the other of the first and second sections comprises fibers oriented generally transverse to the hoop direction.

27. The collar of claim 26 , wherein substantially all fibers forming the second section are oriented in the hoop direction.

28. The collar of claim 26 , wherein said one of said first and second sections is generally triangular in said cross-section defining a tapered surface reducing in diameter in the axial direction.

29. The collar of claim 28 , wherein said one of said first and second sections being generally triangular in said cross-section is formed by said substantially all fibers being axially oriented.

30. The collar of claim 28 , wherein the tapered surface comprises two tapered surface portions tapering at different angles in cross-section as measured along the axially extending plane.
