1.中小直径焊管用定减径机连续生产用于冷冻设备、液压设备、刹车系统、加热设备及装饰的小直径(4.76～13mm)薄壁(0.5-1.5mm)管是用以下方法生产的: ——冷拔无缝管; ——冷拔铜管; ——双层钎焊管(通常称作“BUNDY”管); ——冷拔焊管。这些管子越来越多地用配有定减径机(而不仅仅是定径机)的机组来生产。这种发展的主要原因在于: ——直流焊管技术配以冷减径的工艺得
1. Small and Medium Diameter Welded Pipe Continuous Production of Thin-Walled (0.5-1.5mm) Small Diameter (4.76 ~ 13mm) Thin-Wall Tubes for Refrigerating Equipment, Hydraulic Equipment, Brake Systems, Heating Equipment and Decoration, : - cold drawn seamless pipe; - cold drawn brass; - double brazed pipe (commonly referred to as “BUNDY” pipe); - drawing pipe. More and more of these pipes are produced with units equipped with sizing machines, not just sizers. The main reasons for this development are: - DC welded pipe technology coupled with cold reduction process
