Re-Grooving Tube Hole in Tube Sheet

Re-grooving tube holes in a tube sheet is a process used to repair damaged or worn tube holes in a heat exchanger tube sheet. Over time, the tube holes in the tube sheet can become damaged or worn due to the constant expansion and contraction of the tubes. Re-grooving involves cutting new grooves or channels in the tube sheet to accommodate new tubes. Re-grooving tube holes in a tube sheet is a complex process that requires specialized equipment and experienced technicians.

General overview of the re-grooving process:

• Inspection: The tube sheet is inspected to identify any damaged or worn tube holes that need to be re-grooved.
• Grooving: The damaged or worn tube holes are re-grooved using specialized equipment, such as a tube sheet grooving machine. The grooves are cut to the correct depth and spacing to accommodate the new tubes.
• Tube Installation: The new tubes are then installed into the re-grooved tube holes, typically using a tube expander to ensure a secure fit between the tubes and the tube sheet.
• Testing: The heat exchanger is then tested to ensure that the new tubes are properly installed and there are no leaks or other issues.
