Choke (sports) - Wikipedia

In sports, a choke is the failure of a sportsperson or team in a game in a situation where maintaining their performance is highly important. This can occur in a game or tournament that they are strongly favored to win, or in an instance where they have a large lead that they squander in the late stages of the event.

Chokes - Worldwide Oilfield Machine

used in high erosive and high pressure drop service. The externally guided flow sleeve controls the opening and rate of flow. This choke is used for low capacity/high pressure drop appliions. The flow is directed upward away from the outlet, impinges on itself in the centre of the flow cage which

Flow through chokes - PetroWiki

A wellhead choke controls the surface pressure and production rate from a well. Chokes usually are selected so that fluctuations in the line pressure downstream of the choke have no effect on the production rate. This requires that flow through the choke be at critical flow conditions.

Choke & Kill and Mud Boosting Lines – Offshore Line Pipe

To ensure the stability of the well in this situation, the riser is equipped with two high-pressure auxiliary safety pipes, called Choke & Kill lines. A third auxiliary pipe, called the Mud Boosting line, is used for injecting an additional flow of mud at the bottom of the riser to facilitate the return of the cuttings.

Choke Line - an overview | ScienceDirect Topics

2/3/2012· On the other hand, if the operator maintains choke pressure constant during a shut-in operation, the choke line friction pressure is reduced to 0, reducing the bottomhole pressure by the choke line friction pressure, P fcl, and allowing an additional influx. There is a very simple solution, one that has gained acceptance in the industry.
