What Is PACTape and Why Proper Installation Matters

PACTape is a petrolatum-based anti-corrosive tape manufactured by WQ Trade, used to protect pipes, valves, cables, and structural metal from corrosion. While the tape itself offers excellent barrier properties, installation technique is critical to achieving long-term protection. Poor wrapping, incomplete coverage, or neglect can compromise performance.

This guide walks you through best practices for applying PACTape correctly, helping you maximise the life of your infrastructure.

Key Steps in Installing PACTape

1. Surface Preparation

• Clean the metal surface thoroughly to remove rust, mill scale, paint, dirt, oil, and moisture.
• Use a wire brush, sandpaper, or mechanical cleaning method as needed.
• Ensure the surface is dry before applying the tape to prevent moisture entrapment.

2. Overlap and Tension

• Stretch the tape slightly during application to maintain tension and compress the petrolatum compound.
• Overlap each wrap by around 50 percent to ensure full barrier coverage and eliminate gaps.
• Maintain consistent tension to avoid loose areas or air pockets.

3. Wrapping Around Irregularities

• Where pipes meet or there are welds, bends, or flanges, ensure you mould the tape snugly to the profile.
• Use multiple passes or partial cuts to allow the tape to follow contours without lifting or creating voids.

4. Application of Outer Wrap (Mechanical Protection)

• For added mechanical and weather protection, wrap with PVC outer wrap (non‑adhesive) after applying PACTape.
• The PVC outer wrap acts as a shield from UV, abrasion, and physical damage.
• Align outer wrap edges cleanly and avoid wrinkles.

5. Inspection and Maintenance

• After installation, inspect for loose ends, pinholes, or exposed tape edges.
• Check periodically, especially in harsh environments.
• Rewrap or repair any compromised sections promptly to maintain the integrity of the protective barrier.

Common Pitfalls and How to Avoid Them

• Leaving gaps or using improper overlap, always ensure 50 percent overlap.
• Wrapping loosely or without tension,  maintain consistent tension to compress the tape.
• Skipping surface prep,  any residue or moisture will undermine adhesion and effectiveness.
• Omitting the outer wrap in exposed areas,  mechanical protection is essential in many field conditions.

Benefits of Installing PACTape Correctly

• Enhances the long-term corrosion resistance of pipes, fittings, and metal interfaces.
• Minimises the need for frequent maintenance and repair interventions.
• Reduces downtime and associated costs in industrial, mining, or water infrastructure.
• Ensures full return on investment for the anti-corrosion system.
