U-tube heat exchanger, isShell and tube heat exchangerA type consisting of components such as tube plates, casings, and tube bundles, etc.

In the same diameter, the U-tube heat exchanger has a larger heat exchange area; it features a simple, compact structure with high sealing performance, is easy to inspect and clean, consumes less metal at high temperatures and pressures, and is cost-effective; the U-tube heat exchanger has only one tube sheet, offering good thermal compensation and strong pressure-bearing capacity, making it suitable for operation under high-temperature and high-pressure conditions.

The main structure of the U-tube heat exchanger includes tube box, cylinder, end caps, heat exchange tubes, connecting pipes, baffle plates, anti-surge plates, and guide tubes, anti-short-circuit structures, supports, and other accessories for the shell and tube side.

The U-tube heat exchanger features only one tube plate, with both ends of the tubes fixed on the same plate. The tubes can freely expand and contract, eliminating thermal stress and offering excellent thermal compensation. The tube side employs a double-pass design, resulting in a longer flow path, higher flow velocity, and superior heat transfer performance. It has strong pressure-bearing capacity, allowing the tube bundle to be removed from the shell for easy maintenance and cleaning. Additionally, its structure is simple and cost-effective.
