Problems solved by technology
Its internal structure is compact and the tube bundles are tightly arranged. During the processing, it is easy to cause the product size to exceed the standard deviation, resulting in the product being scrapped.
When the size of the heat exchange tube is large and the tube wall is thicker, the manufacturing difficulty is doubled, especially the tube threading process, which takes up most of the time in the entire process and becomes a bottleneck restricting the production of wound heat exchangers

The invention discloses a portable pipe traction device which aims to solve problems of high cost of traction equipment for high and low-pressure heaters and high pipe penetrating difficulty of wound heat exchangers in the prior art. The portable pipe traction device comprises an expansion device, a first connector, a tension device and a second connector. The first connector is connected with the expansion device, the second connector is connected with the tension device, the first connector is connected with the second connector, the expansion device comprises a central spindle, a limiting plate, cones, a jaw, a washer and a pre-tightening nut, the limiting plate, the first cone, the jaw, the second cone, the washer and the pre-tightening nut are sequentially arranged on the central spindle, each cone is in the shape of a circular truncated cone, the jaw is tubular, and the tubular wall of the jaw is ladder-shaped. The portable pipe traction device has the advantages that the portable pipe traction device is simple in structure, convenient to use, wide in application range and high in cost performance, and is portable, the quality of a product and the pipe penetrating efficiency can be effectively improved, the production cycle is shortened, and the production cost is lowered.
Description
technical field [0001] The invention relates to the field of pressure vessels, in particular to the field of manufacturing high-pressure heaters, low-pressure heaters and heat exchangers, in particular to a portable tube introducer. Background technique [0002] In recent years, with the promotion of national energy conservation and emission reduction policies, people's concept of energy conservation and environmental protection, and awareness of energy reuse have gradually increased. High-pressure heaters, low-pressure heaters and heat exchangers have been widely used in chemical industries and other industries. important, even irreplaceable. High-pressure heaters and low-pressure heaters have adopted many new materials and new methods in design, manufacture, installation, and commissioning. The development has been relatively mature, and the manufacturing process is relatively complete. However, in the process of manufacturing the high and low pressure heaters, the tracti...
