Fire protection wrap K-flex K-FIRE PIPE WRAP 82 mm for pipes – K-flex

K-flex K-FIRE PIPE WRAP 82 mm is a passive fire protection wrap designed for sealing pipe penetrations in walls and floors. It is intended to preserve the fire resistance of building compartments by wrapping around service pipes, closing gaps and helping to limit the spread of fire and smoke. The product is manufactured for mechanical services, HVAC and plumbing installations where maintaining compartmentation around pipe penetrations is required.

Advantages

The wrap is shaped for easy installation around circular pipes and provides a continuous protective layer that restores the fire-resistance integrity of penetrations without the need for complex on-site machining. Its 82 mm nominal width matches common pipe sizes and allows a tidy fit; the material is flexible to accommodate routing changes and fitting adjustments. Using a dedicated firestop wrap helps ensure compliance with passive fire protection practices and reduces the need for bulky collars or cast-in components.

Suitable for

• Sealing circular pipe penetrations through fire-rated walls and floors
• Mechanical services and HVAC pipe routes requiring firestopping
• Plumbing installations where compartmentation must be maintained
• Retrofit and new-build applications where a wrap solution is preferred

Key specifications

• Nominal wrap width: 82 mm for circular pipe applications
• Material: flexible fire-resistant wrap formulated for passive firestopping
• Application type: around pipes to close annular gaps and restore fire integrity
• Compatible installations: walls and floors with service penetrations for mechanical and plumbing systems

How to use

Measure the pipe and penetration to confirm the 82 mm nominal wrap is suitable for the pipe diameter and the annular opening. Wrap the K-FIRE PIPE WRAP tightly around the pipe so the material covers the full circumference and overlaps where required to create a continuous barrier. Position the wrapped pipe within the penetration and compress or adjust the wrap so that it fills the annular space between pipe and surrounding structure. Follow any additional fixing, sealing or retaining methods recommended for the building assembly to ensure the wrap remains in place and the penetration maintains the required fire-resistance rating.

Usage recommendations

Verify compatibility with the specific pipe material and the required fire-resistance rating for the wall or floor assembly. Use the correct wrap width for the pipe size and follow project fire-stopping layout and inspection procedures. For rated assemblies, refer to relevant test evidence or installation instructions from the manufacturer to confirm performance and compliance with local codes.
