User Manual for SIP 12T Hydraulic Pipe Bender

Quick Guide

The SIP 12T Hydraulic Pipe Bender is designed for bending steel pipes (galvanized and black). It is not suitable for thin-walled tubes like copper. Always operate on a level, stable surface and ensure the work area is clear of bystanders.

Description

The unit features a 12-ton hydraulic ram and comes with six bending formers to accommodate various pipe sizes. It is a manual tool requiring physical operation of the pump handle.

Safety Instructions

• Capacity: Never exceed the 12-ton maximum capacity.
• Material: Use only for steel pipe. Do not use for thin-walled tubes (e.g., copper) or for compressing springs.
• Operation: Always operate on a level, stable surface. Never stand on the product.
• Maintenance: Keep hands and limbs clear of moving parts. Do not adjust safety overload valves.
• Protection: Always wear eye protection and heavy protective clothing.
• Inspection: Before use, check for cracked welds, loose bolts, or oil leaks. Do not use if damaged.

Operation

The tool includes six bending formers for British Standard Pipe (BS1387) sizes: 1/2", 3/4", 1", 1-1/4", 1-1/2", and 2 inches.

1. Setup: Place the pipe in the former. Secure guide rollers using the R-clips.
2. Valve Control: Close the hydraulic valve by turning it fully clockwise.
3. Bending: Pump the operating lever gently. For best results, bend progressively by adjusting the guide rollers.
4. Removal: Once the bend is complete, open the hydraulic valve (turn anticlockwise) to release pressure and remove the work.
5. Former Removal: If the former sticks, use a hammer and brass drift to tap it gently. Never hammer directly on the edges of the former.

Maintenance

• Cleaning: Keep the tool clean.
• Storage: Store in an upright position with the ram in its lowest position. Do not store on its side to prevent air from entering the system.
• Bleeding the Ram: If performance is poor due to air in the system:
  • Keep the ram in a vertical position.
  • Close the release valve (clockwise).
  • Remove the rubber bung on the upper cylinder.
  • Pump the handle several times to expel air.
  • Replace the rubber bung.
