Integral lifting bails are a type of lifting equipment used in the oil and gas industry to lift and move heavy loads, such as drill pipes, drill collars, and other tubulars.

These lifting bails are typically made from high-strength alloy steel and are designed to be attached to the top of a tubular or tool joint using a threaded connection. The bails have a loop or eye at the top for attaching a lifting hook or crane, and are rated for a specific weight capacity.

Integral lifting bails are preferred over other types of lifting equipment, such as slip-type bails or collar-type bails, because they are designed to provide a secure and stable lifting point that is directly integrated into the tubular or tool joint. This reduces the risk of the load slipping or becoming unstable during lifting and helps ensure a safer lifting operation.

Integral lifting bails are commonly used in drilling operations to move drill pipe, casing, and other tubulars in and out of the wellbore. They are also used in well intervention and completion operations, as well as in the transportation and storage of tubulars.
