Shell-and-tube heat exchangers are currently the most widely used heat exchangers in chemical and alcohol production. It is mainly composed of a shell, a tube sheet, a heat exchange tube, a head, a baffle plate and the like. The required materials can be made of ordinary carbon steel, copper or stainless steel. In the heat exchange, a fluid enters from the joint pipe of the head, flows in the pipe, and flows out from the outlet pipe at the other end of the head, which is called the pipe process; another fluid enters from the pipe of the casing, from The other joint on the casing flows out, which is called a shell-and-tube heat exchanger.
Features
1. High heat transfer coefficient: the threaded pipe is a high-efficiency heat transfer element combined with internal and external threads made of copper or stainless steel with high thermal conductivity. The threaded tube heat exchanger made of it has a small fluid resistance. Strong turbulence is formed, which greatly increases the heat release coefficient inside and outside the tube.
2. Compact structure: The heat transfer area per unit volume of this product is large. The total heat transfer coefficient is high, so the floor space is greatly reduced, saving material and space.
3, not easy to scale: due to the special concavo-convex structure of the threaded tube, the multi-layer layer and the rotating shape scouring effect inside and outside the tube, combined with the heat extension and contraction of the tube, no impurities remain inside and outside the tube wall, so it is not easy to scale Long-term operation is good.
4, not easy to leak: This product has a short sealing circumference. The thick thread of the threaded pipe is similar to the expansion joint. It has its own compensation ability. The heat exchanger has small thermal stress and is not easy to leak.
5, easy to install: This series of heat exchangers are available in horizontal and vertical versions for easy installation in different locations.
