Product range

CALSIS; Visual inspection, and measurement, of internal root profile of pipeline welds.

The CALSIS is currently in use on landlines inspecting, and measuring root profile in stainless steel and clad pipe welds. The interchangeable scanning heads and wheel sets allow the CALSIS to operate in pipe sizes from as small as 110mm I.D., making this the most versatile internal inspection tool of its kind.

The CALSIS can be deployed either as an independent unit driven by an electric crawler, on reach rods, or attached to the pipeline internal line up clamp (depending on project requirements). The 1-kilometre wireless transmission system makes the CALSIS the perfect tool for land line closing welds, allowing the inspector clear HD video, and root profile measurement down to 50 microns resolution.

ALXIII Series

The ALXIII Series is the most advanced welding data logging system available to date.

The ALXIII Portable is a 'go-anywhere' battery/mains powered unit capable of monitoring all types of arc welding in the workshop at a remote location. Each of the high capacity rechargeable NiMH battery packs powers the ALXIII for up to three hours of weld monitoring. 

Also available as a two-channel or four-channel unit, the ALXIII Workstation can be utilised in many different applications and is the industry workhorse for the international oil and gas pipeline section. The unit has all the facilities of the ALXIII Portable but allows one unit to monitor up to four welding heads from a single location.

In addition, the ALXIII RS can easily turn your own laptop or desktop PC into an advanced arc welding data logging and monitoring system.
