In industrial maintenance, especially in heat exchanger servicing, the safe and efficient handling of tube bundles is crucial. Tube bundle pulling machines (or extractor/insertion systems) have become essential tools for minimizing downtime and preventing damage during maintenance.
Here's a step-by-step guide on their proper use:
1. Preparation & Safety Checks
- Ensure the heat exchanger is depressurized, drained, and cooled.
- Verify that lifting equipment (cranes, hoists) is rated for the bundle's weight.
- Inspect the pulling machine’s alignment, cables, and hydraulic systems (if applicable).
2. Bundle Extraction Process
Step 1:** Attach the pulling machine’s harness or clamping mechanism to the tube bundle.
Step 2:** Apply steady tension to slide the bundle out of the shell. Hydraulic systems may assist for heavy bundles.
-Step 3:** Support the bundle during extraction to avoid bending or dropping.
3. Transport & Cleaning
- Use roller conveyors or forklifts to move the bundle to the cleaning area.
- Clean tubes (chemically, hydro-blast, or mechanically) and inspect for defects.
4. Bundle Reinsertion
Step 1:** Align the bundle precisely with the shell.
Step 2:** Use the pulling machine in reverse (or a pusher attachment) to guide the bundle back smoothly.
Step 3:** Confirm proper seating and reassemble end caps/bolting.
### **Why It Matters**
- **Safety:** Reduces manual handling risks.
- **Speed:** Cuts downtime by 50% compared to traditional methods.
- **Precision:** Prevents costly tube damage.
