Liquid-O-Ring 236 Metal-Free Tool Joint and Drill Collar Compound provides maximum protection to the drill string. Liquid-O-Ring 236 prevents galling, seizing, thread damage, and excessive wear resulting in prolonged tool joint and drill collar life. This non contaminating tool joint and drill collar compound resists washout and will not harden or dry out in the connection. Liquid-O-Ring 236 is a metal-free tool joint and drill string compound which enables ease of makeup and breakout of all joints and provides the required thread and shoulder protection under various operating conditions. The absence of metals and presence of corrosion inhibitors make Liquid-O-Ring 236 a superior tool joint and drill collar compound. It is an environmental alternative to compounds which contain metals such as zinc or copper.

Applications

• THREAD PREPARATION: MAKE SURE PIPE THREADS ARE CLEAN AND FREE OF ALL CONTAMINANTS. DO NOT apply 236 before proper conditioning has been done to pipe which has been exposed to H2 S, CO2, or downhole chemicals. Carefully wash threads with Aqua Cure™ 690 to remove any salt deposits, residual chlorine from thread cutting operations, dirt, and grease. Use a stiff or wire brush to remove all rust and corrosion. DRY THREADS COMPLETELY BEFORE APPLICATION. All residual water from cleaning procedure, re-threading operations or hydrostatic testing should be completely dried and treated using moisture displacer, such as 130 Water Displacer and Corrosion Inhibitor
• APPLICATION INSTRUCTIONS: Liquid-O-Ring 236 Metal-Free Tool Joint and Drill Collar Compound should be applied with a #2 dope brush or other equipment specifically designed for use with thread compounds (avoid using a paint brush). Use the dope brush bristles to force the compound into the roots of the threads. Take care to cover the entire threaded area. A VISUAL INSPECTION IS ADVISED. For optimum protection apply Liquid-O-Ring 236 to thread protectors as well. If these procedures are not followed, corrosion and pitting may occur
• INSPECTION: One month after application of 236, thread protectors should be randomly removed and inspected for corrosion. Subsequent inspections are recommended every three months
