Abstract

Techniques for implementing a pipeline system that includes a first pipeline component to be fluidly connected to a pipe segment, which includes tubing that defines a pipe bore and a fluid conduit within an annulus of the tubing, and a second pipeline component that includes a female fitting connector that defines a connector cavity. The first pipeline component includes a male fitting connector that defines a first connector bore and an outer surface of a leading end of the male fitting connector includes a retainer tab or base threading. The female fitting connector includes a base portion that defines a second connector bore and a retainer ring that interlocks with the retainer tab or the base threading on the leading end of the male fitting connector to facilitate securing the male fitting connector to the female fitting connector without using a discrete threaded fastener or hot tooling.

Claims (48)

1. A pipeline system, comprising:

a first pipeline component configured to be fluidly connected to a pipe segment that comprises tubing that defines a pipe bore and a fluid conduit within an annulus of the tubing, wherein:

the first pipeline component comprises a male fitting connector that defines a second connector bore; and

an outer surface of a leading connector end of the male fitting connector comprises a retainer tab; and

a second pipeline component comprising a female fitting connector that defines a connector cavity, wherein the female fitting connector comprises:

a base portion that defines a first connector bore, the connector cavity, and a ledge that extends part way into the connector cavity;

a retainer ring that interlocks with the retainer tab on the outer surface of the leading connector end of the male fitting connector to facilitate securing the male fitting connector to the female fitting connector without using a discrete threaded fastener or hot tooling, wherein the retainer ring is disposed within the connector cavity and comprises:

a ring protrusion on an inner surface of a leading ring end of the retainer ring; and

a ring lip; and

a spacer ring disposed in the connector cavity to facilitate securing the retainer ring in the connector cavity at least in part by maintaining the ring lip on the retainer ring interlocked with the ledge.

2. The pipeline system of claim 1 , wherein:

the first pipeline component comprises a bore fluid source, a bore fluid destination, or a first pipe fitting; and

the second pipeline component comprises the bore fluid source, the bore fluid destination, or a second pipe fitting.

3. The pipeline system of claim 1 , wherein the retainer tab on the outer surface of the leading connector end of the male fitting connector slides under and interlocks with the ring protrusion on the retainer ring of the female fitting connector to facilitate securing the male fitting connector to the female fitting connector.

4. The pipeline system of claim 3 , wherein:

a leading inner edge of the retainer ring in the female fitting connector comprises a female taper; and

a leading outer edge of the retainer tab on the male fitting connector comprises a male taper.

5. The pipeline system of claim 1 , wherein the female fitting connector or the male fitting connector comprises a connector seal compressed between opposing side surfaces of the female fitting connector and the male fitting connector to facilitate sealing the second connector bore of the male fitting connector and the first connector bore of the female fitting connector from external environmental conditions.

6. A method of assembling a pipeline system, comprising:

aligning a first connector bore defined by a female fitting connector in a first pipeline component with a second connector bore defined by a male fitting connector in a second pipeline component, wherein the female fitting connector comprises:

a base portion that defines the first connector bore, a connector cavity, and a ledge that extends part way into the connector cavity;

a retainer ring disposed within the connector cavity of the female fitting connector, wherein the retainer ring comprises a ring protrusion on an inner surface of a leading ring end of the retainer ring and a ring lip; and

a spacer ring disposed in the connector cavity of the female fitting connector to facilitate securing the retainer ring in the connector cavity at least in part by maintaining the ring lip on the retainer ring interlocked with the ledge; and

securing the male fitting connector to the female fitting connector at least in part by:

inserting a leading connector end of the male fitting connector into the connector cavity defined in the female fitting connector; and

engaging the retainer ring of the female fitting connector with an outer surface of the male fitting connector to facilitate fluidly connecting the first pipeline component and the second pipeline component via the first connector bore of the female fitting connector and the second connector bore of the male fitting connector without using a discrete threaded fastener or hot tooling.

7. The method of claim 6 , wherein:

the outer surface of the leading connector end of the male fitting connector comprises a retainer tab that extends radially outward; and

securing the male fitting connector to the female fitting connector comprises inserting the male fitting connector into the female fitting connector until the retainer tab on the male fitting connector slides under and interlocks with the ring protrusion on the retainer ring of the female fitting connector.

8. The method of claim 7 , wherein:

a leading inner edge of the retainer ring in the female fitting connector comprises a female taper to facilitate sliding the retainer tab on the male fitting connector under the retainer ring;

a leading outer edge of the retainer tab on the male fitting connector comprises a male taper to facilitate sliding the retainer tab under the retainer ring in the female fitting connector; or

both.

9. The method of claim 7 , wherein securing the male fitting connector to the female fitting connector comprises compressing a connector seal between opposing side surfaces of the male fitting connector and the female fitting connector to facilitate sealing the first connector bore of the female fitting connector and the second connector bore of the male fitting connector from external environmental conditions.

10. A system, comprising:

a female fitting connector that defines a connector cavity, wherein:

the female fitting connector is configured to be secured to or integrated with a first body of a first pipeline component; and

the female fitting connector comprises:

a retainer ring disposed within the connector cavity, wherein the retainer ring comprises a ring lip;

a base portion that defines a first connector bore, the connector cavity, and a ledge that extends part way into the connector cavity; and

a spacer ring disposed in the connector cavity to facilitate securing the retainer ring in the connector cavity at least in part by maintaining the ring lip on the retainer ring interlocked with the ledge; and

a male fitting connector that defines a second connector bore, wherein:

the male fitting connector is configured to be secured to or integrated with a second body of a second pipeline component; and

the male fitting connector is configured to be disposed within the connector cavity of the female fitting connector such that the retainer ring in the female fitting connector interlocks with an outer surface of the male fitting connector to facilitate fluidly connecting the first pipeline component and the second pipeline component via the first connector bore of the female fitting connector and the second connector bore of the male fitting connector.

11. The system of claim 10 , wherein:

the retainer ring of the female fitting connector comprises a ring protrusion on an inner surface of a leading ring end of the retainer ring; and

the outer surface of a leading connector end of the male fitting connector comprises a retainer tab that is configured to slide under and interlock with the retainer ring in the female fitting connector to facilitate securing the male fitting connector to the female fitting connector.

12. The system of claim 10 , wherein the male fitting connector is configured to be secured to the female fitting connector without using a threaded fastener or hot tooling.
