Expansion of underground hot oil transport lines has been an ongoing challenge for engineers and designers. Native site soil or imported soil can place too much restriction on the expanding pipe causing undue pipe stress which leads to cracks, problems or failures.
Engineers for the Holly Refinery turned to Gilsulate 500XR for their solution to address expansion of their 189°F hot oil underground pipes. Using Gilsulate 500XR’s published mechanism for expansion compensation along with conducting underground pipe stress analysis; the engineer of record determined that using Gilsulate on their elbows and branches would provide the necessary flexibility for their critical expansion areas.
The field and design flexibility of Gilsulate 500XR offers engineers solutions to some of their challenging designs which other products just cannot solve. Let Gilsulate help you with your next refinery project!
