The main properties of domestic (Karbon-2) and three overseas (HAKUFORM 50-65-2, Multan 7040, ToolWay ST) cooling lubricants (coolant) are studied, making it possible to evaluate quantitatively their efficiency in welded pipe manufacture. The effect of different coolant grades on depth of score marks and surface roughness of welded steel pipes at the Filit Moscow Pipe Plant is studied. An integral method is proposed for evaluating coolant quality under plant conditions.
