What are the general stainless steel heat exchange tube materials?

2022-06-08

The exchanger has been widely used in many fields at present. The heat exchanger is made of food grade stainless steel, which has the characteristics of anti-rust and anti-scaling. Stainless steel heat exchange tube is one of the components of the heat exchanger, used for heat exchange between two kinds of media, usually in simplified Chinese, in our production and life more and more widely used.

Commonly used materials are:

304 stainless steel; 304 stainless steel is widely used in stainless steel heat exchange tube, the core role of the heat exchange tube is to conduct the heat generated by the gas out, the better the thermal conductivity, the better the heat exchange. 304 stainless steel has good thermal conductivity. The processing of stainless steel heat exchange tube is very difficult, the internal structure and welding process requirements are very high. If there is not careful in the manufacturing process, the quality of the whole machine will be affected, and the manufacturing process is risky. 304 stainless steel can be used for stamping, bending and other hot processing, there will be no heat treatment hardening phenomenon.

304L stainless steel; 304L stainless steel has very good weldability. After welding or stress elimination, it can maintain excellent intergranular corrosion resistance, thermal shock resistance is higher than 304 stainless steel, making the machine more stable and reliable.

The above two different materials of stainless steel heat exchange tube can be customized according to customer requirements, there is a need to call consultation.
