Premium Connection Tubing

Brief Introduction:

All the thread connections of casing and tubing which are not specified by API 5CT are called premium connections generally. These threads are designed to achieve high properties of connections.

Premium connections are used to achieve gas-tight sealing reliability and 100% connection efficiency under more severe well conditions. Severe conditions include:

 

High pressure;

High temperature;

Sour environment;

Gas production;

High-pressure gas lift;

Steam well;

Large dogleg (horizontal well);

 

Also, efficiency in flush joint, integral joint or other special clearance applications improves connections. A large diameter (> 16 in.) pipe improves the stab-in and makeup characteristics; galling should be reduced; and connection failure under high torsional loads (e.g., while rotating pipe) should be prevented.

NO.
