ASOE Pipe-in Liner

Nuflow has partnered with ASOE Hose Manufacturing to deliver a new, innovative pipe relining process. Pipe-in Liner is a non-structural liner constructed from Fabric Reinforced Flexible Plastic Pipe (FRFPP). The installation method requires folding the Pipe-in Liner into a U-shape, before pulling it into the host pipe and expanding it. Once in place, it functions as a leakage-free liner within the host pipe.

Common applications

Suitable water pressure pipes at normal temperatures:

Water mains, fire mains, and rising mains ranging from DN50-DN1400.

Potable water:

ASOE Pipe-in Liner is approved for potable pipes and drinking water systems.

Key features of ASEO Pipe-in Liner

Enhanced durability

With no structural connection between the liner and the host pipe, it increases durability by operating independently.

Optimal flexibility

The Pipe-in Liner can be easily pulled through 45 or 90-degree bends with a 5D radius.

Maintains shape

No matter how much or little internal or external pressure, the liner maintains its round shape within the host pipe.

Increased capabilities

The Pipe-in Liner requires a small working zone and has limited restrictions on pipe conditions.

Abrasion-resistant

Made from a high-tenacity fabric reinforcement layer, the hose liner is resistant to abrasion.

High burst pressure

Completed assets can withstand pressure between 3000 kPa - 12000 kPa.

50 years

The Pipe-in Liner possesses a long design life of 50 years within a range of circumstances.

Simpler installation

With no resin or curing needed, the installation process can be much more streamlined.

Highly certified

Compliant with several standards, including AS/NZS 4020:2018 and NSF 61.

ASOE Pipe-in Liner repair process

1

Pipe inspection

Before we begin, we inspect the pipes with CCTV cameras and use the footage to assess the best approach.

2

Clean and clear

We clear out the host pipe using high-pressure water jetting tools.

3

Pipe-in Liner installation

After preparing the area, we fold the liner into a U-shape, bind it with tape, and pull it into the host pipe.

4

Finalising the repair

We conduct an air pressure test, install rendition pipes, and conduct a final CCTV inspection to ensure quality.

QUALITY ASSURANCE

Tested to ensure ASOE is compliant with all international standards
