The quality of stainless steel finned tubes is mainly evaluated based on the fin ratio (the ratio of the surface area of the finned tube to the bare tube area) and the bonding rate (qualified according to the national standard of 88%). The adhesion rate refers to the ratio of the heat transfer coefficient when there is a gap between the fin and the base tube, that is, when there is contact thermal resistance, to the heat transfer coefficient when there is no gap and the contact thermal resistance is zero. The wing ratio range of steel aluminum composite finned tubes is between 13.5-22.7, which can meet the needs of various process conditions The bonding rate is over 90%, ensuring that the heat transfer efficiency does not deteriorate during long-term use in working environments with temperatures below 210 degrees Celsius.
