Which two materials are often used in stainless steel heat exchange tubes? 8/18/2023 10:20:58 AM

   Zhejiang Shengguang Stainless Steel Co., Ltd. is a relatively large-scale stainless steel pipe manufacturer in Zhejiang Province. The company mainly produces and sells stainless steel seamless tubes and boiler heat exchange tubes as the leading products, which can produce Φ6-630mm and thickness 1-30mm. The main steel types are: 300 series stainless steel, duplex steel, high-nickel alloy, etc. Special materials and specifications can be produced according to customer needs, and the production and sales of stainless steel welded pipes, stainless steel pipe fittings, stainless steel flanges, valves and other products are attached.

   The commonly used materials for stainless steel heat exchange tubes are 304 and 304L. The following Shengguang Stainless Steel will introduce you.

304 stainless steel:

   304 stainless steel is widely used in stainless steel heat exchange tubes, which have good thermal conductivity, and its core function is to transfer the heat generated by the gas. The better the thermal conductivity, the better the heat exchange.

   The processing of stainless steel heat exchange tubes is difficult, and its internal structure and welding process requirements are high. If you do not pay attention to the manufacturing process, it will affect the quality of the whole machine, and there are risks in the manufacturing process. However, 304 stainless steel can be used for hot processing such as stamping and bending. Heat treatment and hardening occur.

   304L stainless steel:

   304L stainless steel has good welding performance. After welding or stress relief, it can maintain excellent intergranular corrosion resistance. Its thermal shock resistance is higher than that of 304 stainless steel, which can make the whole machine more stable and reliable.

   The two materials of the stainless steel heat exchange tube can be selected according to the actual situation.
