Developments for cold stretched reduced tubing

摘要

Formtek Metal Forming Inc, USA, has developed a new concept within the carbon steel, small diameter tubing markets, specifically aimed at the cold stretched reduced tubing market. Under the Yoder brand name, the cold stretched reduced process assists tube producers in manufacturing tubing that is usually used in the automotive fuel line, appliance refrigerator, and other small diameter markets. The new process specifically targets tubing that is too small for high frequency induction welding (where impeders are too small for this range). Producers of this tubing need the speed that high frequency or square wave welding can offer to meet production requirements.
