Fast Cure Bakerlok ® Thread-Locking Compound replaces welding for casing joints on the bottom lengths to prevent unscrewing while drilling out cement. Welding of shoes, couplings, and collars to casing often weakens the casing and should be avoided wherever possible.
Withstanding High Breakout Torque. Tests under bottom hole temperatures ranging from 50º through 400º F showed Bakerlok® withstood greater torque than a standard joint welded in three places with 2 inch beads.
Unaffected by Vibration. At 400º F Bakerlok® was subjected to a steady breakout torque for 8 hours while under continuous vibration from a 6 pound air hammer. Breakout torque was increased until six times the 3,300 ft-lb makeup torque finally broke the joint.
High Lubricity. Tests were made using Bakerlok® on one side of a standard coupling and API Modified Thread Dope on the other. Identical pin threads were made up into the coupling. For the same amount of torque, the joint with Bakerlok® made up further and was cooler than the joint lubricated with standard thread dope. Bakerlok® has a .9 Friction Factor/Torque Factor.
Leak proof Seal. Joints made up with Bakerlok® using standard torque were tested with water pressures in excess of the listed burst pressure of the casing. The joint showed no leakage.
Corrosion Resistant. Five different samples of Bakerlok® covered steel and underwent a 96 hour ASTM and salt spray test. The result: no visible change in Bakerlok®; no acceleration of the normal corrosion rate on the five samples of steel.
