AI vision inspection of high-pressure cylinders
A maker of high-pressure gas cylinders cut inspection time by 22% with an AI vision system
Problem
ENK makes high-pressure cylinders used in shipbuilding and for specialty gases. Each cylinder must be inspected, and inspection time is part of the production cycle.
Approach
As a participant in the Ministry of Trade, Industry and Energy's AI Factory leading project, the company introduced an AI vision inspection system for its cylinders. The ministry reported the result in August 2026, after reviewing 42 early sites out of about 170 it had supported.
Results
Takeaway
ENK reported a 22% reduction in cylinder inspection time, while another site in the same programme reported 90%. The programme published no common measurement method for comparing the results.
