This paper describes an improved design of end closure for screw locking ring U-shaped tube heat exchanger used in oil-refining process with use of the D-section shearing bolts as its load-carrying connectors between the tube channel cover and the top flange instead of the connection by acme screw locking ring and the strength calculating method for its main load-carrying components and an comparison with two others are presented. This new construction has the features of compacted design, saving material and easy assembling and disassembling etc.
