Pipe Repair Packer – Inflatable CIPP Point Repair for Trenchless Pipe Rehabilitation

Our pipe repair packer (also known as inflatable pipe packer, CIPP point repair packer, or pipe patch packer) is a reusable, high-strength inflatable bladder designed for trenchless repair of localized pipe defects. Used with epoxy-saturated fiberglass patches, it seals cracks, holes, leaks, and root intrusion in sewer, water, gas, and industrial pipelines. Ideal for municipal and residential pipe rehabilitation without excavation.

What is a Pipe Repair Packer?

A pipe repair packer is an inflatable rubber bladder that is inserted into a damaged pipe, positioned at the defect, and inflated to press a resin-impregnated patch against the pipe wall. After the resin cures, the packer is deflated and removed, leaving a permanent, smooth, and structural repair. This trenchless point repair method saves time, reduces costs, and minimizes disruption compared to traditional dig-and-replace methods.

Our packers are made from high-grade EPDM rubber with Kevlar reinforcement, providing excellent durability, chemical resistance, and high inflation pressure capacity. They are reusable for hundreds of cycles when properly maintained.

Key Features

• Trenchless repair – No excavation needed; rehabilitate pipes from inside.
• Reusable – Designed for 100+ uses with proper care.
• High pressure – Withstands inflation pressures up to 3.5 bar.
• Flexible & durable – EPDM + Kevlar reinforcement resists abrasion and chemicals.
• Wide diameter range – Available for pipes from DN50 mm to DN1500 mm and larger.
• Bypass option – Central bypass tube allows water flow during repair (for live lines).
• Easy positioning – Can be pushed with air rods or pulled with winch cable.
• Compatible with epoxy & polyester resins – Works with standard CIPP patch materials.

• Man-entry pipes – Large diameter concrete or steel pipes.

How to Use a Pipe Repair Packer (Step-by-Step)

1. Inspect – Use a CCTV camera to locate the defect and measure pipe diameter.
2. Prepare patch – Cut fiberglass or felt patch to size; saturate with epoxy resin.
3. Attach patch – Wrap the wet patch around the deflated packer and secure with wire or string.
4. Insert – Push or pull the packer to the defect location (use air rods, push rods, or winch).
5. Inflate – Connect air compressor to the packer’s air line; inflate to specified pressure (e.g., 1.5-2.0 bar). Hold pressure.
6. Cure – Wait for the resin to harden (time varies by resin type and temperature).
7. Deflate & remove – Release air, withdraw the packer.
8. Post-inspect – Run CCTV to verify repair quality.

   

Frequently Asked Questions (FAQ)

Q: How many times can a pipe repair packer be reused?

A: With proper cleaning and storage, our packers can be reused 100+ times. Regular inspection for cuts or abrasion is recommended.

Q: Can the packer be used in pipes with flowing water?

A: Yes, for live lines we recommend our bypass pipe packer which has an internal hose that allows water to flow through during the repair. For dry or low-flow pipes, standard packers work fine.

Q: What resin should I use with the packer?

A: Use epoxy-based or polyester resins formulated for CIPP point repair. We can supply compatible resin upon request.

Q: Can it repair bends or elbows?

A: Standard packers are designed for straight pipes. For 90° elbows and P-traps, use our bendy packer which has extra flexibility and a shorter length.

Q: How do I determine the correct packer size?

A: Measure the internal diameter of your pipe. Choose a packer whose nominal range includes your pipe ID. For example, a DN150 packer fits pipes 100-200 mm. Provide your pipe size and we will recommend the right model.

Q: Do you offer custom packer sizes?

A: Yes, we manufacture custom packers for non-standard diameters (up to DN1200) and special lengths. Minimum order quantity applies. Send your specification.
