“NW” Series Tube Sheet Grooving Tool
The SAPSONS “NW” Series Tube Sheet Grooving Tool is a precision tool used to make internal grooves in tube sheet holes for heat exchangers, condensers, boilers, and chillers. These grooves help secure tubes firmly during tube expansion, improving joint strength and leak prevention.
The tool features an automatic eccentric cutting mechanism, adjustable groove depth, and interchangeable pilots and cutters for different hole sizes. It provides fast, accurate, and consistent grooving performance, making it suitable for industrial fabrication and maintenance applications.
Key benefits include:
- Accurate and smooth grooving
- Stronger tube-to-tube sheet joints
- Easy adjustment and operation
- Wide diameter range coverage
- Reliable performance in heavy-duty industrial use
Description
The SAPSONS “NW” Series Tube Sheet Grooving Tool is a precision internal grooving tool specially designed for creating grooves inside tube sheet holes during the manufacturing and maintenance of heat exchangers, condensers, chillers, and boilers. These grooves help in mechanically locking expanded tubes firmly into the tube sheet, improving joint strength and leak resistance.
SAPSONS uses an automatic eccentric tool-holder mechanism, where the cutter activates automatically once the pilot nose touches the tube sheet face. The cutter then feeds smoothly into the bore to produce accurate grooves with controlled depth and position.
Key Features :
- High precision and fast grooving operation
- Adjustable groove depth and groove location
- Covers a wide range of bore diameters by changing pilots and cutters
- Automatic feed mechanism for consistent groove quality
- Quick-lock collar and stop nut for easy setup
- Different groove configurations available using form cutters
- Suitable for heat exchanger and condenser tube sheet applications
Typical Applications :
- Heat exchanger manufacturing
- Boiler tube sheet grooving
- Condenser tube installation
- Chiller and pressure vessel fabrication
- Tube expansion and tube locking operations
Technical Range (Typical) :
| Tool Model | Tube Sheet Hole Diameter | Max Groove Depth |
| 1SNW2MT | 9 – 32 mm | 2.0 mm |
| 3SNW3MT | 16 – 45 mm | 3.5 mm |
| 4SNW4MT | 19 – 48 mm | 4.5 mm |
| 6SNW5MT | 38 – 114 mm | 7.6 mm |
