Feature Safety Product or CAP Series.
The steel mill opted for the CAP rectangular windows which could do the job of three traditional round IR windows and offered a greater field of view from a single installation. Instead of fitting 368, 3in diameter units, the mill was able to reduce the IR window installation to 176, making savings on product and installation costs. The customer ordered 160 CAP-12 units, a model with 12in wide IR window and cover, and just 16 IRISS VPFR-75, 3in diameter IR windows.
Once the IRISS IR windows and ultrasound ports were installed, inspection became a one-person job as there was no requirement to remove panels or wear increased levels of PPE.
Without IR windows the total man hours for one round of inspection was 416 hours. After the installation, the mill confirmed an overall reduction in man hours of 95%. Furthermore, it was possible to inspect critical assets, a process previously deemed impossible due to safety risk implications.
Cost analysis
Prior to the arc flash review, the mill’s IR inspections were completed live and involved personal protective equipment, live works procedures, risk assessments, permits, etc. The resultant cost analysis is based on the following parame- ters: Inspection takes 24 days per year based on an eight hour day; two x PPE suit-ups per day, 30 minutes per person, per suit up; one hour per compartment panel removal, etc. x two for a two-person team; 169 individual panels to be inspected.
Thanks to the IRISS products, live IR and ultrasound inspection of 176 critical assets can now be completed safely by one person while the systems are in-cycle and under full load condi- tions. Furthermore, the inspections can be com- pleted with greater ease, allowing an increased frequency to reflect industry best practice of four times per year. The potential of criti- cal asset failure at the
mill is now vastly reduced, production losses are averted and the company’s commercial reputation is assured.

with socket housing: established name, new possibilities. with socket housing expands the pioneering connector series from HARTING with a solution
for cable connection along a surface. The housing sizes 30 and 60 with a maximum of four lateral cable entries in metric thread sizes M25, M32 and M40 enable the exible realisation of a space-saving cable guide. Together with the possibility of contact bridging a new application arises: a space-saving distribution cabinet. Find more information under phone +44 (0)1604 827500 or send an e-mail to
