Metal-Free Tool Joint & Drill Collar Compound


Molyslip® ECOSLIP OCTG is a premium performance, metal-free, tool joint & drill collar compound based on high-quality vegetable oil thickened with calcium soap. The product contains specially selected solid lubricants coupled with high levels of corrosion inhibitors, anti-oxidant and anti-wear additives that make the product particularly suitable for use under the most aggressive conditions in corrosive wet/humid, dirty or chemical environments where a high degree of water washout resistance is required.

MO Molyslip® ECOSLIP OCTG has excellent lubricating and anti-wear properties to reduce friction during assembly preventing galling, ‘pick-up’ and seizure facilitating consistent joint make-up and easier breakout for routine maintenance. The product is formulated to meet the requirements of *API RP 5A3 / ISO 13678:2010.

Molyslip® ECOSLIP OCTG is effective over a wide temperature range and is specifically designed to prevent seizure of threaded connections and ‘cold welding’ of rotary shoulder/drill collar/tool joint connections on oilfield equipment such as drill strings, casings, production tools and tubing etc. The specially formulated blend of additives provides enhanced adhesion to cold/wet tooling and a high resistance to wash off whilst being thermally stable making it suitable for use in applications where high temperatures are encountered.

MOLYSLIP ECOSLIP OCTG is biodegradable and compliant with the requirements of HOCNF ‘E’ classification in the UK/NL and ‘Yellow’ rating in Norway.

*API RP 5A3/ISO13678:2010 – “Petroleum and natural gas industries-evaluation and testing of thread compounds for use with casing, tubing, line pipe and drill stem elements”.
