Stress characteristics of casing joint

Make up torque. The casing joint must be tightened to a certain torque before it can be put into oil and gas wells. For API threaded joints, the size of the make-up torque is specified in API RP 5c2.

Characteristics of casing joint

The main functions of oil casing are as follows: 1). Loose sealing, collapsing and leaking formation; 2). Sealing oil, gas and water layers to prevent collusion, thus forming oil and gas channels; 3). Installing wellhead to control oil and gas flow, so as to facilitate drilling and production.
