product description

The tube plate inner hole slotting device is referred to as a slotting device, which is also known as a slot cutter, a slot cutter, and a slotting device, and is a special cutter for slotting the inner hole of the tube sheet before the expansion tube. After the pipe hole is grooved, the sealing property and the pulling force of the pipe and the pipe plate connection after the expansion of the pipe system are increased, the connection strength with the pipe is greatly improved, the loosening and stretching are not easy, and the pipe which is expanded when the pipe is expanded can be reduced or eliminated. Thermal expansion and contraction or other factors caused by gaps or pores caused by expansion problems and troubles. The accuracy of the groove in the inner hole of the tube plate directly affects the quality of the tube. The A, B, C, E series slotting device is a special device for slotting the inner hole of the heat exchanger tube plate which can meet the requirements of hydraulic strength expansion.

I. Introduction

 

With the wide application of hydraulic strength expansion technology, the requirements for tube plate slotting are getting higher and higher, and the user's original self-made simple slotting device can not meet the requirements of hydraulic strength expansion to open 8-12mm wide groove. Therefore, in order to solve the problems of this part of the user, the company has successfully developed a tube plate slotter that can meet the requirements of the hydraulic strength expansion groove.

YFK-8A, 8B, 8C, 10A, 10B, 10C, 12A, 15A series slotting device is a special device for slotting the inner hole of heat exchanger tube plate which can meet the requirements of hydraulic strength expansion. It is our company adopting the United States. And a domestic multi-purpose slotter designed and improved by domestic advanced technology. They are composed of three parts: (1) the main body, (2) the arbor, and (3) the blade. Different types of slotting machines are available according to customer requirements. The shank and blade are customized according to user requirements. The shank is custom made to the aperture and the blade is customized to the groove width.

Second, special features

1. High production efficiency, 1-2 holes per minute can be opened;

2, automatic positioning, adapt to the common hole of various specifications of the pipe hole;

3, 3-6-3 double groove molding, 6-15 single groove molding;

4. High quality and good reliability of slotting;

5, can be grooved according to the requirements of hydraulic expansion;

6, can choose any shape slotting tool (example: rectangular, triangular, single slot, double slot, etc.).
