Investigators say a hydraulic fitting failure set off the 2022 B-2 incident at Whiteman AFB, ending in a gear collapse, wing fire and $300M repair bill. The U.S. Air Force has released the Accident ...

Couplings are probably the most compliant and predictable component in a motion system. Turn up the speed, however, and it's a different story. Learn how to address this engineering issue. Couplings ...

In recent years, environmentally-assisted cracking has caused failures of many Grade P110 couplings during fracturing operations, causing enormous economic loss to the oil and gas industry. Factors ...

Operators can avoid failure of couplings during hydraulic fracturing by using a design window when designing a casing string. Hydraulic fracturing treatments produce higher stress levels in couplings.

Materials — When complicated geometry proves more trouble than it’s worth, the deceptively simple function of transmitting torque can be improved by even small changes in chemical makeup. The core ...
