Description

Technical Field

[0001] The utility model relates to the field of pipe threading tooling, in particular to a pipe threading tooling for a U-tube heat exchanger. Background Technique

[0002] A heat exchanger is a heat exchange device. The main function of the heat exchanger is to transfer part of the heat of the hot fluid to the cold fluid. Heat exchangers play an important role in many industrial production fields such as chemical industry, petroleum, power, and food. Heat exchangers play a very important role in industrial applications and can effectively adjust the temperature of the fluid to meet the requirements of various technological processes.

[0003] A U-tube is a tube with a U-shaped shape and can be used for transporting fluids. A U-tube heat exchanger is a type of shell-and-tube heat exchanger and belongs to petrochemical equipment. It is composed of main components such as a tube box, a shell, and a tube bundle. The U-tube heat exchanger gets its name because its heat exchange tubes are U-shaped. When assembling a U-tube heat exchanger, pipe threading assembly needs to be carried out between the U-tube and the plate body on the heat exchanger.

[0004] However, when the prior art performs pipe threading assembly between the U-tube and the plate body on the heat exchanger, it requires workers to manually perform pipe threading assembly between the U-tube and the plate body on the heat exchanger. When workers manually perform pipe threading assembly between the U-tube and the plate body on the heat exchanger, it is not conducive to stably threading the U-tube and is likely to cause wear on the U-tube.

[0005] Therefore, we propose a pipe threading tooling for a U-tube heat exchanger. Content of the Utility Model
