Abstract

An assembly and method for stiffening a flexible member according to which a stiffening member and an adapter surround the flexible member and an insert extends in an annulus between the adapter and the flexible member.

Claims (39)

1. An assembly for stiffening a flexible member, the assembly comprising:

a stiffening member extending over a portion of the flexible member;

an adapter secured to the stiffening member and extending over another portion of the flexible member in a spaced relation thereto to form an annulus;

an insert disposed in the annulus; and

a ring connected to an end of the stiffening member, and wherein an end of the adapter is secured to the stiffening member by a weldment extending between the adapter and the ring.

2. The assembly of claim 1 wherein the insert is secured to the adapter and to the ring.

3. The assembly of claim 2 wherein the insert is secured to the adapter and to the ring by a weldment extending between the insert and the adapter, and by a weldment extending between the insert and the ring.

4. The assembly of claim 1 wherein the insert is secured to the adapter.

5. An assembly for stiffening a flexible member, the assembly comprising:

a stiffening member extending over a portion of the flexable member;

an adapter secured to the stiffening member and extending over another portion of the flexible member in a spaced relation thereto to form an annulus; and

an insert disposed in the annulus, wherein the insert is secured to the adapter;

wherein the insert is secured to the adapter by a weldment extending between the insert and the adapter.

6. The assembly of claim 1 wherein the flexible member is a pipe and wherein the stiffening member, the adapter, and the insert are cylindrical.

7. An assembly for stiffening a flexible member, the assembly comprising:

a stiffening member extending over a portion of the flexible member;

an adapter secured to the stiffening member and extending over another portion of the flexible member in a spaced relation thereto to form an annulus; and

an insert disposed in the annulus to prevent the adapter from contacting said another portion of the flexible member, wherein the insert is fabricated from a material to eliminate wear of said another portion of the flexible member;

wherein the flexible member is a pipe and wherein the stiffening member, the adapter, and the insert are cylindrical;

wherein the insert is formed by two semi-circular insert portions.

8. A method for stiffening a flexible member, the method comprising:

surrounding a portion of the flexible member with a stiffening member;

surrounding another portion of the flexible member with an adapter that extends in a spaced relation to the flexible member to form an annulus;

securing the adapter to the stiffening member;

inserting an insert into the annulus; and

connecting a ring to an end of the stiffening member, and wherein the step of securing comprises welding the adapter to the ring.

9. The method of claim 8 further comprising securing the insert to the adapter and to the ring.

10. The method of claim 9 wherein the latter step of securing comprises welding the insert to the adapter and to the ring.

11. The method of claim 8 further comprising securing the insert to the adapter.

12. A method for stiffening a flexible member, the method comprising:

surrounding a portion of the flexible member with a stiffening member;

surrounding another portion of the flexible member with an adapter that extends in a spaced relation to the flexible member to form an annulus;

securing the adapter to the stiffening member;

inserting an insert into the annulus; and

welding the insert to the adapter.

13. The method of claim 8 wherein the insert is made of an elastomer material.

14. The method of claim 8 wherein the insert is made of polyurethane.

15. The assembly of claim 5 wherein said insert is fabricated from an elastomer material.

16. The assembly of claim 5 wherein said insert is fabricated from polyurethane.
