Abstract
A connection for oilfield use is disclosed. It features male and female components held together by dogs actuable through one of the members and into the other. Different configurations of the connections envision a built-in preload to the connection when made-up. This is accomplished by a cantilevered component at the extremity of one of the components of the connection. Alternatively, the preload feature can be incorporated into the dog or other locking assembly that holds the components of the connection together. The connection is particularly useful in subsea chokes which have a removable insert which can be mounted to or removed from the choke body which is located subsea.
Claims20
A connector, comprising:
- a male component insertable into a female component;
- a compliant portion on one of said male and female components which elastically moves to apply a preload when said male and female components are assembled to each other;
- a lock mechanism extending at least in part into said male and female components to selectively hold them together with said compliant portion applying said preload.
A connector, comprising:
- a male component insertable into a female component;
- a compliant locking member movable between a retracted position where said male and female components can be brought together or separated and a locking position where said locking member both holds said male and female components together and applies a preload force to said connected components.
