The bearing capacity of stainless steel heat exchanger tube is affected by two factors:

1. Raw materials: The raw materials for processing and producing stainless steel heat exchange tubes are mainly austenitic stainless steel 201, 304, 304L, 316, 316L, etc. It is not excluded that some heat exchange tube manufacturers' heat exchange tubes are made of duplex stainless steel welding pipes. Different raw materials lead to different performance of stainless steel heat exchange tube, for example: duplex stainless steel tube has high strength and corrosion resistance, compared with the general 316L austenitic stainless steel heat exchange tube, the stainless steel heat exchange tube produced with it has better wear resistance, corrosion resistance and corrosion fatigue resistance, different raw materials will lead to different pressure bearing capacity of stainless steel heat exchange tube.

2. Specification and size: the commonly used stainless steel heat exchange tube size (outer diameter x wall thickness) is mainly φ19mmx2mm, φ25mmx2. 5mm and φ38mmx2. 5mm stainless steel pipe φ25.

HAOSTEEL insists on manufacturing "high-quality steel pipe" and focuses on serving the high-end market. At present, the company has become a qualified supplier of nuclear power plants in China, and continues to supply large quantities of nuclear power plants such as Shandong Nuclear Power Plant and Guangdong Nuclear Power Plant. At the same time, it is listed as an excellent qualified supplier by famous petrochemical, nuclear power, coal-to-oil, boiler and pressure vessel manufacturers at home and abroad.
