How to manufacture the shell and tube heat exchanger I
How to manufacture the shell and tube heat exchanger I Shell and tube heat exchanger is a kind of heat transfer device, which is composed of shell, tube plate, tube bundle, baffle and cover; How is the manufacture to produce the shell and tube heat exchanger ? In the manufacturing of heat exchanger, the manufacturing process of cylinder, head and other parts is the same as that of general container manufacturing progress, but the requirements are different. The inspection of materials, drilling of tube plate and baffle hole, welding of cylinder and processing of flange are the key points to the quality. Throughout its manufacturing process, most of manufacturer still use traditional processes, in which the proportion of welding is relatively high, so it is necessary to weld in strict accordance with the welding process, and to detect the weld. The heat exchanger produced by H.Stars Group subsidiary company UAR, has gone through 18 processes. It has been meticulously processe
