What is a stainless steel precision tube?
Stainless steel precision tube refers to a type of stainless steel tubing manufactured with tighter dimensional tolerances, enhanced surface finishes, and superior mechanical performance compared to standard stainless steel tubes or carbon steel pipes. These high-precision tubes are engineered for applications that demand extreme accuracy, high cleanliness, and excellent corrosion resistance. Unlike regular stainless steel tubes, precision stainless steel tubing undergoes more rigorous quality control in terms of outer diameter tolerance, wall thickness, and surface treatment, ensuring minimum deviation and maximum performance. This makes it highly valued in high-tech, medical, and industrial applications.

Which material is used for boiler tubes?
Boiler tubes are a specialized type of piping designed to operate in high-temperature, high-pressure environments. Tube specifications are generally defined by outer diameter (or side length) and wall thickness, and range from fine capillary sizes to large-diameter tubes measuring several meters across. These tubes are widely used in industrial boilers, heat exchangers, power stations, and related thermal equipment, where they serve as critical components. Based on temperature performance, boiler tubes are categorized into general boiler tubes and high-pressure boiler tubes.
