Spiral Plate, Tubular, & Shell-and-Tube heat exchangers

The spiral plate type is a new type of heat exchanger with good heat transfer efficiency, high running stability and multiple working together. High heat transfer efficiency, high operational reliability, and low resistance. However, the spiral plate heat exchanger requires high welding quality and is difficult to overhaul. Heavy weight, poor rigidity, special care should be taken when transporting and installing spiral plate heat exchangers.

The tubular heat exchanger is currently the most widely used heat exchanger in chemical and alcohol production. It is mainly composed of a casing, 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 exchanger, 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.
