Quality requirements and control of hot dip galvanizing for oval fin tube

The oval finned tube is the cooling element on the tube bundle of the direct air cooler. Because of the particularity of the use environment of the direct air cooler, the surface of the air cooler must be treated with good anti-corrosion treatment. Our factory uses hot-dip galvanizing for the anti-corrosion of the oval finned tube surface. In order to improve the service life of the air cooler. The quality requirements for hot-dip galvanizing of the elliptical finned tube include not only the general requirements for the quality of hot-dip galvanized parts, but also the special requirements for the quality of the dipping of the elliptical finned tube as the cooling element. Analyze the hot-dip galvanizing quality requirements of the elliptical finned tube, and explain how to perform the hot-dip galvanizing quality control of the elliptical finned tube.

Quality requirements and control of hot dip galvanizing for oval fin tube

Elliptical finned tube is the cooling element on the tube bundle of the direct air cooler.

Because of the particularity of the use environment of the direct air cooler, good anti-corrosion treatment should be carried out on the surface of the air cooler, It not only includes the general requirements for the quality of hot-dip galvanized parts, but also includes the special requirements for the quality of elliptical finned tubes as cooling elements.

This paper analyzes the quality requirements of hot-dip galvanized elliptical finned tubes, and expounds how to control the quality of hot-dip galvanized elliptical finned tubes
