Deep hole tube sheet drilling machine series

Tube sheets are widely used in tubular heat exchangers, boilers, pressure vessels, steam turbines, large central air conditioners and other industries.

Mainly used in chemical vessels, such as tubular heat exchangers, pressure vessels, boilers, condensers, central air conditioners, evaporators, and seawater desalination, to support and fix the tubular. Rigid and has great thermal conductivity.

The tube sheets used for the third and fourth types of pressure vessels require relatively high precision. The traditional hole processing method is the fitter scribing and the rocker drilling hole. In recent years, with the large-scale chemical container, the diameter and thickness of the tube sheet are also increasing, and the CNC technology is also introduced into the processing of the tube sheet. The use of machining centers for high-efficiency and high-precision hole processing has gradually been accepted by some large enterprises. At present, the demand for large and heavy tube sheets in the fields of nuclear power, seawater desalination, and central air-conditioning heat exchangers is showing an increasing trend.

In the inspection process of the tube sheet, the main inspection indicators are the hole position, the hole diameter tolerance, the smoothness in the hole, the presence or absence of burrs, the position of the groove, etc. For the double tube sheet, more attention is paid to the hole position during the inspection process. Hole fit is very important. The large-scale CNC three-axis deep hole drilling machine independently developed and designed by our company can be guaranteed.
