The blind flange launched sideways like a disc, struck a cable tray support, and embedded itself into a concrete firewall. … Read more
Two junction boxes sat on the receiving dock last Thursday morning. Both rated for Zone 1 gas environments, both from the same manufacturer, both containing identical internal components. One carried a CE mark with ATEX Category 2G designation. The other displayed an IECEx Certificate of Conformity number with EPL Gb. A procurement engineer on a … Read more
The fractionation train had been running the same feed composition for eleven months straight. When the operations team switched to a heavier feed slate from a new upstream well, they treated it as a routine adjustment — a tweak on the DCS, a revised set point, nothing that needed paperwork.
