Stainless Steel Fixed Tube-Sheet Shell and Tube Heat Exchanger
TEMA/API 660/NB/ASME U Certified
Yuhong Fixed Tube-Sheet Shell and Tube Heat Exchanger
Reliable Heat Transfer Solutions for Wide Industrial Applications
Fixed tube-sheet shell and tube heat exchangers represent the most widely used, dependable, and cost-effective category of industrial heat exchangers. With a straightforward yet robust structure, high operational stability, and easy maintenance, they serve as key equipment for heating, cooling, condensation, and evaporation in countless industrial processes. Yuhong is a professional manufacturer focusing on the design, production, inspection, and after-sales service of fixed tube-sheet heat exchangers, supporting standard models as well as fully customized solutions to meet diverse working conditions across chemical, petrochemical, HVAC, water treatment, food processing, textile, pharmaceutical, and general manufacturing industries.
Product Structure & Working Principle
Yuhong fixed tube-sheet heat exchangers consist of a cylindrical shell, tightly fixed tube sheets at both ends, a precisely arranged tube bundle, channel covers, and connecting nozzles. The tube bundle is securely expanded and welded to the tube sheets, ensuring excellent sealing and mechanical strength. One fluid flows inside the tubes (tube side), while the other fluid flows through the shell side around the tubes. Heat is efficiently transferred through the tube wall between the two media without direct mixing.
Due to the rigidly fixed tube-sheet design, this type of heat exchanger is especially suitable for relatively clean fluids, steady temperature conditions, and applications where thermal expansion differences are not extreme. For applications with larger temperature differences between shell and tube fluids, we can optionally integrate an expansion bellows on the shell to relieve thermal stress and extend service life.
