LIQUID PREPARATION SUITABLE FOR APPLICATION AS A LUBRICATION LAYER ON METAL COLD WORKED OBJECTS, AFTER DRYING ON METAL OBJECTS AND PROCESS FOR PRODUCING METAL PIPE WITH A LAYER OF A SOLID LUBRICANT, WHICH PIPE IS SUITABLE FOR TAPERING, DRAWING OR FOR BOTH TAPERING AND DRAWING

摘要

A lubricant composition including ethoxylated long chain primary alcohols and, preferably, boron compounds but excluding most other previously used organic lubricant materials gives superior results in tube pointing operations, especially with thick walled tubes, and is also useful for drawing operations, either subsequent to pointing or independently of pointing, where very high quality surface finishes are desired.
