CLEANWELL® DRY is an anti-corrosion and lubricating dry system applied in the mill on the surface of VAM® threads. Developed for Carbon steel and 13CR material, CLEANWELL® DRY 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® DRY will generate no discharge nor unnecessary handling from the mill to the rig. Take off the protector and run it !
