industrial stainless steel U tube/shell and tube heat exchanger with good price

Description of the heat exchager

 A kind of shell and tube heat exchanger, which belongs to petrochemical equipment, is composed of a tube box, a shell and a tube bundle, and so on. The U shaped tube heat exchanger has only one tube plate, and both ends of the pipe are fixed on the same pipe plate.This kind of change the characteristics of heat exchanger tube bundle can be freely telescopic, not the tube due to the temperature difference between the shell and thermal stress, thermal compensation performance is good; for tube side of a double tube pass, process is longer, higher velocity, heat transfer performance better; ability to work under pressure; tube bundle can be extracted from the shell, to facilitate the inspection repairing and cleaning and simple structure and low cost. But in tube cleaning inconvenience, bundle in the middle part of the pipe is difficult to replace and because of the bending radius of the inner tube is not too small, in the tube plate with a central part of cloth tube is not compact, so the pipe number can not be too much and in the central part of the tube bundle gap exists, the shell side fluid easily and the impact of short-circuit in the shell side of the heat exchanger. In addition, in order to make up for the reduction of the pipe wall of the elbow, the straight pipe part of the wall thickness of the pipe. This affected the use of the occasion, it is only suitable for pipe shell wall temperature difference is larger, or the shell side of the medium is easy to scale and the pipe is clean and not easy to scale, high temperature, high pressure, corrosion of the situation.
