Tube Bundle Dryer for Alcohol
Technical Advantages
All heat exchanger tubes and tubesheets are joined by strength expansion.
Since the first tube bundle dryer manufactured in 2001, expansion jointing technology has been used all the time. Due to the special structure of the tube bundle dryer, the flexible deformation of the middle steel tube is drooped up to 15 mm. During the rotation of the tube bundle, alternating stress is generated, which acts on the root of the steel tube and the tube sheet. The carbon content is reduced due to the heat affected zone of the weld. The strength is reduced, so the steel pipe is easy to break. So we use a fully expanded process.
