CLEANWELL® Zero is an anti-corrosion and lubricating semi-dry system applied in the mill on the surface of VAM® threads. Developed for Carbon steel and Corrosion resistant alloy materials, CLEANWELL® Zero is designed to prevent the use of thread compounds that have proved to damage the environment, affect health and safety or contaminate downhole equipments and producing formation . Using CLEANWELL® Zero  will generate no discharge nor unnecessary handling from the mill to the rig. Take off the protector and run it !
