摘要

The technical and economic indices of the production of cold-worked pipes and their surface quality can be substantially improved by using new highly effective coatings and lubricants when preparing the billet in drawing. For this purpose the "Filit" joint-stock company (Moscow Tubular Products Plant) developed a low-waste technology of chemical preparation of carbon steel pipes for short-mandrel and mandrel-free drawing based on using new chemical compositions and copper plating, phosphatizing, neutralizing, and soaping conditions.
