Production of stainless steel heat exchange tube to do several things?

Stainless steel tube as we all know, in fact, stainless steel heat exchange tube is a kind of stainless steel tube, it is one of the important components of stainless steel heat exchanger, the main role is to exchange the existence of heat between the two. The quality difference of heat exchange tube directly affects the heat exchange work and heat exchange results of heat exchanger, so the choice of heat exchange tube, to choose the regular manufacturers in line with the production standards, Huatian stainless steel is a focus on the production of stainless steel heat exchange tube enterprises. Because the heat exchange tube may be a mixture of steam, water, soda and corrosive medium, the use of more diversified conditions, so before the copper tube to a certain extent can not meet the needs of heat exchanger components, stainless steel heat exchange tube has emerged as The Times require, become the replacement of copper tube heat exchange tube. Stainless steel heat exchange tube has the characteristics of good safety, heat exchange performance and economy, so stainless steel heat exchange tube is commonly used in recent years.

Since it comes to the stainless steel heat exchange tube, let's talk about its production of raw materials. Can do the heat exchange tube of stainless steel material has 201 stainless steel, 304 stainless steel, 304L stainless steel, 316 stainless steel, 316L stainless steel and so on, due to their different chemical composition, also affect the corrosion resistance of stainless steel heat exchange tube, and their respective stainless steel heat exchange tube price is also very different, such as: Compared with 304L stainless steel, the corrosion resistance of 316L stainless steel tube is better, if the 316L stainless steel tube is used to process the stainless steel heat exchange tube, the corrosion resistance will be improved naturally, so if the medium is highly corrosive, the priority will be 316L stainless steel tube to process the production of stainless steel heat exchange tube.

In understanding the production of stainless steel heat exchange tube raw materials, we will look at the processing of stainless steel heat exchange tube production of raw materials, mainly heat treatment, grinding treatment, pickling passivation and so on, a specific point, is:

1, heat treatment, in fact, is to carry out solution heat treatment of stainless steel pipe. The hardness of u-shaped heat exchange tube bend section without heat treatment and subsolid solution treatment will increase with the decrease of bending radius, so in order to better use stainless steel heat exchange tube, we have to carry out solid solution heat treatment of stainless steel pipe. It is worth noting that the low solution temperature affects the solution treatment effect, and the microstructure and hardness of stainless steel heat exchange tube can not get ideal results; The temperature is slightly higher, there may be stainless steel U-shaped pipe section inside the concave or cracks and other defects.

2, grinding processing, the requirements of this light is made of stainless steel tube), commonly used dry grinding, grinding wire drawing oil, 8 k mirror processing industries, among them, the ground wire drawing oil is relatively common, because 304 series stainless steel reflects the very good adornment effect after oil mill, grinding surface is more delicate, uniform, antirust effect is more outstanding.
