HAELOK, now available in Australia and New Zealand through Technofast Industries, gastight fittings can be deployed in less than a minute to provide pipe seals in both systems and as retrofits in existing system, especially systems that have vibration and high pressure.

The HAELOK is used where vibrations and pressure pulses require the highest level of safety. The connectors are compatible with all natural refrigerants such as carbon dioxide (R744/CO2) in sub and trans-critical pressures from 40 bar up to 160 bar, ammonia (R717/NH3) and hydrocarbons such as propane (R290/C3H8), propylene (R1270/C3H6) and isobutane (R600a/C4H10).

HAELOK fittings are applicable to a range of applications such as power stations, oil, gas and petrochemical refineries.

“Pipe installation and repair work in such applications has to date often involved welding, which means you need a hot works permit, a spotter, x-raying, flushing, purging and a shutdown period – all of which take time and adds considerable cost. With a HAELOK fitting, one person can complete the repair in approximately 40 seconds and the pipe is ready to go,” Technofast Industries owner John Bucknell says.

“You can also isolate the particular area you are working on, rather than shutting down the whole line. Then, simply hydraulically cut the pipe, install the relevant HAELOK fitting, crimp the ends and the job is complete.”

The system can overcome difficult operating and space-limited installation conditions with its simplicity. It is a cost-attractive alternative to conventional joining techniques such as welding and brazing.

The HAELOK range includes 250 standard sizes and variations such as straight fittings, reduction fittings, fittings with internal or external threads, end caps, union tees, elbow 90° fittings, SAE flanges and more.
