Rapp-it® Pipe Repair Tape / Bandage | 3.6m × 100mm | RAP124 | Emergency Pipe Repair System

Water-Activated Fibreglass Pipe Repair Bandage for Fast Emergency Repairs on Steel, PVC, Copper, Polypipe and Fibreglass Pipes

Supply Solutions Group supplies Rapp-it® Pipe Repair Bandage – 100mm × 3.6m (Part Number RAP124) to organisations operating across mining, manufacturing, engineering, marine, oil and gas, agriculture, utilities, maintenance and industrial workplaces throughout Australia.

Rapp-it RAP124 is a fast-acting emergency pipe repair bandage designed to provide a strong repair solution for damaged or leaking pipes and hoses.

The repair bandage consists of a woven fibreglass material impregnated with water-activated polyurethane resin.

When activated with fresh water and wrapped tightly around a properly prepared damaged pipe, the resin begins curing and forms a hard, reinforced repair around the affected area.

The RAP124 bandage measures 100mm wide × 3.6 metres long, making it suitable for appropriate medium and larger pipe-repair applications where increased bandage width provides practical coverage.

Rapp-it is designed for use on many common piping materials, including:

• Steel

• Polypipe

• PVC

• Fibreglass

• Copper

The system is engineered for demanding industrial applications and is commonly used where a leaking or damaged pipe needs to be repaired quickly to help reduce operational downtime.

Rapp-it specifies resistance to internal pressures of up to approximately 2500 kPa / 360 psi under suitable conditions.

The cured bandage also offers temperature resistance up to approximately 150°C / 300°F.

A key advantage of the Rapp-it repair system is its water-activated curing technology.

The bandage is immersed in fresh temperate water for approximately 10–20 seconds before application.

Once activated, it is wrapped firmly around the prepared repair area.

Rapp-it recommends extending the bandage approximately 50mm beyond each side of the leak and building a substantial repair thickness using multiple wraps.

The repair begins setting rapidly, with the manufacturer specifying a typical set time of approximately 20–30 minutes.

The material can also set underwater, providing useful versatility for appropriate wet-environment applications.

For the strongest repair, Rapp-it recommends a completed bandage thickness of at least approximately 10mm, generally achieved using around 12–15 wraps.

Rapp-it Pipe Repair Bandages can be used across emergency maintenance environments where conventional pipe replacement or welding may not be immediately practical.

The system is particularly relevant to mining, processing, marine, agricultural and industrial operations where leaking pipes can create expensive production downtime.

The Rapp-it Pipe Repair System typically combines the activated fibreglass bandage with Rapp-it Steel Putty, which is used to fill or seal the damaged area before the bandage is wrapped around the pipe.

This listing is for the RAP124 100mm × 3.6m pipe repair bandage configuration.

As an Indigenous-owned industrial supplier and procurement partner, Supply Solutions Group provides Rapp-it pipe repair products, maintenance consumables, adhesives, sealants, PPE and industrial supplies backed by responsive customer service, procurement support and Australia-wide business supply capability.

Why Choose Rapp-it® RAP124 Pipe Repair Bandage?

Rapp-it RAP124 provides a practical emergency-repair solution for situations where pipe damage could otherwise result in substantial downtime, fluid loss or disruption to operations.

Traditional pipe repair methods can require:

• Welding

• Pipe replacement

• Specialist tooling

• Extended shutdowns

• Replacement fittings

• Significant labour

Rapp-it provides an alternative emergency repair method using a water-activated fibreglass bandage.

Once activated, the bandage is wrapped tightly around the damaged section and allowed to cure.

The resin hardens into a reinforced composite structure around the pipe, helping create a strong repair without conventional welding or replacement procedures.

Water-Activated Technology

The Rapp-it bandage contains water-activated polyurethane resin.

Activation is straightforward:

1. Remove the bandage from its foil pouch.

2. Immerse it in fresh temperate water.

3. Soak for approximately 10–20 seconds.

4. Squeeze the roll once or twice while submerged.

5. Remove it from the water.

6. Immediately begin wrapping the pipe.

No separate resin measuring or mixing is required.

Rapid Repair Time

Rapp-it describes its system as capable of achieving a successful pipe repair in approximately 30 minutes.

The bandage itself typically sets in approximately 20–30 minutes.

For best results, Rapp-it recommends allowing at least 30 minutes for the completed repair to set rock hard before appropriate return to service.

Longer cure times may improve final repair performance.

High Pressure Resistance

Rapp-it specifies internal pressure resistance up to approximately:

2500 kPa / 360 psi

Actual repair performance depends on factors including:

• Pipe diameter

• Damage size

• Pipe material

• Surface preparation

• Number of wraps

• Repair thickness

• Application quality

• Cure time

• Operating temperature

Repairs should always be carried out according to current Rapp-it instructions.

High Temperature Resistance

The cured Rapp-it bandage is specified for temperatures up to approximately:

150°C / 300°F

This provides useful capability for appropriate industrial pipe systems exposed to elevated operating temperatures.

Suitable for Multiple Pipe Materials

Rapp-it specifies compatibility with most common pipe materials, including:

• Steel

• Polypipe

• PVC

• Fibreglass

• Copper

Correct surface preparation remains critical regardless of substrate.

Works Underwater

An important feature of Rapp-it is that the activated bandage can set underwater.

This provides additional flexibility for repairs in wet environments and situations where completely drying the surrounding area may be difficult.

The damaged surface should still be cleaned and prepared as thoroughly as possible before application.

Surface Preparation

Successful repair performance depends heavily on proper preparation.

Rapp-it recommends:

1. Shut down the affected pipe or hose.

2. Clean away dirt, oil, rust and other foreign material.

3. Roughen the damaged area using a metal file, wire brush, emery paper, rasp or similar tool.

4. Ensure sufficient clean surface is available for the bandage to bond.

5. Prepare the damaged area before activating the bandage.

Roughening the pipe surface helps improve adhesion of both the putty and bandage.

Using Rapp-it Steel Putty

The Rapp-it repair system uses Steel Putty to fill the damaged area before applying the bandage.

Manufacturer guidance includes:

1. Tear off the required amount of putty.

2. Twist and knead it until it becomes a uniform grey colour.

3. Press it firmly into the damaged section.

4. Begin bandage application within the putty's approximately 2–5 minute working time.

The putty helps fill cracks, holes and irregularities before the reinforcing bandage is applied.

Bandage Application

After activation:

1. Begin wrapping quickly.

2. Extend the bandage approximately 50mm beyond each side of the leak.

3. Pull each layer firmly as it is applied.

4. Maintain tight and consistent tension.

5. Continue wrapping until the full bandage is used or adequate repair thickness has been achieved.

6. With wet gloves, squeeze and mould the bandage using a rotating motion.

7. Continue working the surface until the resin stops foaming and begins to set.

A tight application is important for achieving a strong repair.

Recommended Repair Thickness

Rapp-it recommends that the completed bandage repair be at least approximately:

10mm thick

This generally corresponds to around:

12–15 wraps

Insufficient wrapping can reduce repair strength and pressure capability.

Important Safety Information

Pipe repair can involve pressurised systems, hot liquids, hazardous chemicals and stored energy.

Before attempting a repair:

• Shut down and isolate the pipe

• Depressurise the system

• Drain or control contents where required

• Identify the substance carried by the pipe

• Consult relevant Safety Data Sheets

• Wear the required PPE

• Ensure pipe temperature is safe for handling

• Follow site isolation procedures

• Follow Rapp-it application instructions

• Verify chemical compatibility

• Prevent environmental release

• Do not work on a pressurised damaged pipe unless an approved procedure specifically permits it

The manufacturer's pressure and temperature ratings should not be interpreted as permission to apply the product to a live pressurised system.
