Zhejiang Mingxin Stainless Steel Co., Ltd. is a modern stainless steel pipeline system manufacturing enterprise integrating scientific research, production and sales. The company adopts advanced, efficient and mature production management mode. Leading materials for the production of high-quality stainless steel, to provide reliable and safe stainless steel pipes and pipe fittings for global users.
In order to make stainless steel heat exchange tubes meet higher requirements for cold processed products, most of the stainless steel heat exchange tubes need to be cold processed, and the cold processing of stainless steel heat exchange tubes is divided into two processes: cold rolling and cold drawing. What we are going to talk about today is stainless steel. Cold drawing process of heat pipe.
There are three ways of cold drawing:
1. Cold drawing of the plug: the plug with the inner diameter of the finished product is used for cold drawing.
2. Mandrel cold drawing: Use a mandrel with the same length as the stainless steel heat exchange tube for cold drawing. The cold drawing of the mandrel can make the inner wall of the stainless steel heat exchange tube smooth and achieve a large deformation ratio. This method is suitable for Stainless steel heat exchange tubes with long dimensions.
3. Free cold drawing: adopt the cold drawing method without mandrel.
