Traditional laboratory lubrication tests often involve neat oils. However, compared to the cold rolling process, high levels of lubricant degradation and wear are often found. To better approach the situation in the field, laboratory lubrication tests were developed for emulsions. In this paper, the viability of these methods is illustrated by a number of field cases.
Forming, threading, and hydrotesting tubular goods require the use of metalworking fluids, which are usually in the form of water-soluble concentrates that contain mineral oil, synthetic oils, polymers, or a mix of all three.
