Stainless steel heat exchange tubes, single metal pipes and ordinary bimetallic composite pipes are difficult to meet the requirements of the boiler and heat exchanger industry, while meeting seemingly contradictory and demanding performance requirements such as high strength, good thermal conductivity, and good corrosion resistance.

This is because the bimetallic composite tubes made by traditional methods have some insurmountable shortcomings to varying degrees. For example, due to insufficient bonding force, it is impossible to overcome the difficulty of different expansion rates of the two metals in a hot environment (usually the bonding force of composite tubes In 0.2MPa-1.5MPa), heat treatment and other plastic processing cannot be performed, so it cannot be used in many industrial application scenarios.

At present, the existing common bimetallic composite tubes can not meet the requirements for the use of heat exchange tubes for heat exchangers in terms of binding force, heat exchange efficiency and processing technology, and are only suitable for fluid transportation and structural load bearing. Therefore, from the perspective of high efficiency and energy saving, it is of great significance to develop and manufacture boiler and heat exchanger stainless steel heat exchange tube projects.

Customers with this need are welcome to consult Hangao Tech (SEKO Machinery). Our high-speed precision annealed stainless steel heat exchange tube production line can be integrated, welding, grinding, bright annealing, cutting in one. Specific process standards, we can customize and design according to customer requirements.
