Description
Titanium tubesheet is mainly used for chemical containers to support column tubes. Titanium tubesheet is widely used in chemical equipment in high-end because of its excellent corrosion resistance. In addition to provide the titanium tube sheet which has not been machined, Giant Metal also produces the mechanically processed tube sheet according to the drawing from customer. We use CNC drilling machine with the rocker drilling hole processing, effectively ensure the position precision of the double tube sheet hole, aperture of tolerance and aperture finish, greatly improved the quality of the tube sheet.

Applications
Used for shell and tube heat exchanger, boiler, pressure vessel, steam turbine, the large central air conditioning, water desalination, etc.
