Short Description
Bakerlok thread locking compound 8 oz kit

Bakerlok thread locking compound 8 oz kit


Bakerlok Thread-Locking Compound replaces welding for locking 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.

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 furrher and was cooler than the joint not made up with Bakerlok.


Withstands High Breakout TorqueTests under bottom hole temperatures ranging from 50° through 400° F showed Bakerlok withstood greater torque than standard joint welded in three places with 2 inch beads.

Unaffected by Vibration.At 400° F Bakerlok was subjected to steady vibration from a 6 lb air hammer. Breakout torque was increased until six times the 3,000 ft-lb makeup torque finally broke the joint.

Leakproof Seal. Joints made up with Bakerlok using standard torque were testing with water pressures in excess of the listed bursting strength of the casing without any signs of leakage.

Easy Mixing. The Bakerlok formulation ensures stable consistency to permit mixing under a variation of temperatures existing in the field, i.e., from 9 degrees to 115 degrees F.

Ample "Potlife" After Mixing. The selection of the chemicals in Bakerlok provides a "potlife" in excess of one hour; even at temperatures of over 100°F.

Corrosion Resistant.Five different samples of Bakerlok covered steel 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.
