介绍了目前在冰箱管、汽车用刹车管、油管等小直径（１２．７ｍｍ以下）管生产中已普遍使用的冷张减工艺。这种工艺尤其用在焊管生产中，焊管机只生产一种（最多２种）规格的管子，经过冷张减（在线）生产各种小直径管，最小到４．７５ｍｍ（有的到３．８ｍｍ）。使用该工艺有许多优点，诸如，节省能源，没有辐射，收得率高。还举例说明了冷张减机的生产程序。在国内已有山东潍坊、江苏张家港等厂使用这种冷张减设备。本文作者是美国Ｙｏｄｅｒ公司的技术开发部主任。
The cold reduction process that is commonly used in the production of small diameter (12.7 mm or less) tubes such as refrigerator tubes, brake tubes for automobiles and tubing is introduced. This process is especially used in the production of welded pipes. The pipe machine produces only one (up to two) sizes of pipe, cold-reduced (on-line) to produce a variety of small diameter pipes down to 4.75mm (up to 3). 8mm). There are many advantages to using this process, such as energy savings, no radiation, and high yield. Also gives an example of cold reduction machine production process. Weifang in Shandong Province, Zhangjiagang, Jiangsu and other plants using this cold cut equipment. The writer is the director of technology development at Yoder in the United States.
