Molten sulfur hose holds up to high heat

At the North Carolina State Ports Authority in Morehead City on the Atlantic, supply terminals house the chemical molten sulfur used in making of sulfuric acid and other by-products that store PCS phosphates, such as transportation, chemical food processing, and agricultural products.
The nearby supply terminals are close to Morehead's deepwater port that includes a barge slip for bulk-carrying barges to dock and fill up with the molten sulfur, PSC Phosphate products. Molten sulfur is then transported to various industrial destinations along the Eastern Seaboard.
B&B Hose in Wilmington NC has been a longtime hose supplier to PCS Phosphate, but over the years as environmental laws became more stringent, so have the hoses' specifications.
When B&B needed a new source for these specialized hoses, Richard Horton, the firm's general manager, turned to Pete Livengood of the NovaFlex Group.
In this hose's operation, maintaining molten sulfur at a consistent temperature of 275° F during transfer is crucial, or it will solidify. The molten sulfur's temperature must be maintained when it leaves the South American refinery.
Novaflex Hose of Burlington NC designed and supplied a specialized 2"-thick hose complete with built-in carbon steel flanges made specifically for the transfer of molten sulfur. With working pressures of up to 225 psi with material between 270° to 300° F, an extremely robust hose was needed.
Horton admitted that his company tried hoses from some of the competition, but they just didn't hold up. The last hose he bought from Livengood — prior to his joining Novaflex — lasted 12 years. “There is a specialized way of doing it,” said Horton, “and I have great confidence in Pete's expertise. That's why we're now using Novaflex.”
