Integrated cable routing and support systems for refinery process units, utility corridors, tank farms, substations, and control facilities.
Designed to manage power, instrumentation, fiber optic, and emergency shutdown cabling across hightemperature, corrosive, and hazardous refining environments while maintaining operational safety and maintenance accessibility.
Scenario Challenge
Extreme Heat Exposure Around Process Units
Refinery cable systems are frequently installed near furnaces, reactors, steam lines, and flare systems where ambient temperatures and radiant heat can accelerate cable aging and reduce tray coating lifespan.
Corrosion from Sulfur Compounds and Chemical Vapors
Hydrocarbon processing environments expose cable support systems to sulfur compounds, acidic vapors, saline air, and chemical washdown conditions that rapidly deteriorate lowgrade metallic systems.
Dense MultiService Routing in Limited Rack Space
Refineries require simultaneous routing of MV power, LV distribution, instrumentation, DCS, fiber optic, and fire alarm systems within congested pipe rack structures while maintaining EMC separation and maintenance access.
Continuous Operation Requirements During Maintenance
Most refinery facilities operate under limited shutdown windows. Cable systems must support phased expansion, retrofits, and maintenance activities without major interruption to ongoing production.
