NordiTube’s inserted hose pressure liner lands in Australia

With more than 40 years of cured-in-place pipe (CIPP) lining experience, NordiTube Technologies has brought the next level of pressure liners to Australia. 

NordiTube customers profit from scale production, and its manufacturing facilities in America, Vietnam, Europe and China, which creates more economic prices and lower lead times. This extended research and development (R&D) structure allows the company to maintain technical leadership, and high-quality products. 

One result of this is the IH Liner. Inserted hose (IH) liner technology for pressure pipe rehabilitation was first developed in Europe more than 20 years ago. This technology is effective for long distance pressure pipe rehabilitation. 

So far, this technology had been limited on diameters up to DN500. 

Now, NordiTube has brought the IH technology to the next level, by producing pressure liners up to DN1200. Used for the water, sewer main, gas, hot temperature, and oil industries, the IH system range is between 50mm–1200mm and is AS/NZS 4020 approved. 

The IH Liner only requires standard equipment, including a winch, air compressor and a IH tool kit, with supervisor training provided for first installers by NordiTube. 

In New South Wales, Sydney Water utilised this game-changing product on its Strathfield Sewer Rising Main project. 

The rehabilitated section posed a challenge for the designers because of the location and the diameter of the pressure pipe. 

The line was located under two busy roads and a school, which meant that open dig pipe replacement was immediately out of the question. 

To add further challenges, the project had to be completed within a two-week timeframe. 

In total, the length to be rehabilitated was 320m of 750mm mild steel cement lined pipe. The IH Liner, capable of large diameters, allowed the designers the opportunity to match the time frame, diameter size and pressure rating for this challenging project.

After the cleaning, the IH Liner installation was achieved over four days. The set-up of the liner, including the equipment assembly, only took half a day. 

On the second day, the pulling-in was accomplished, with took three hours for the entire 320m length of DN750 liner. Once this was completed, the liner was expanded the next day with an air compressor unit to establish its pre-set round shape. 

The Sydney Water team later installed the two connectors, before a pressure test was conducted, and the line then ready for reconnection.

“We are glad that we could provide Sydney Water with a technology for the trenchless rehabilitation of large diameter pressure pipes,” NordiTube Asia Pacific Business Development Manager Marc Luksch said. 

“Next to the IH Liner, with the WSAA and AUS/NS 4020 for drinking water approved Nordiflow and Tubetex CIPP solutions, NordiTube provides now the full toolbox for pressure pipes of all sizes and lengths to customers in Australia and New Zealand.” 

Starting with its roots in Belgium, NordiTube Technologies quickly expanded to become a market leader in Europe, North America, and Asia in providing pressure rehabilitation solutions for the water, gas, industry and sewer-main markets. 

Now, 40 years later, NordiTube Technologies has manufacturing facilities in Belgium, Vietnam, America, and China. 

The company reaches its customers globally with fast and effective lead times and local technical support offices. 

This is achieved with NordiTube Asia Pacific’s Singapore team and NordiTube Australia – Adelaide covering the technical sales support in the Asia Pacific market.
