Hydraulic System Protection: Used to sleeve high-pressure hoses on heavy machinery to prevent "burst-injuries" and protect against external abrasion. Underground Utility Services: Essential for shielding fiber-optic cables and water lines from soil shifting and accidental excavation damage. Oil & Gas Processing: Employed as a "jacket pipe" in subsea or overland pipelines to provide mechanical protection and secondary containment. Bridge & Highway Construction: Utilized to cover post-tensioning tendons and structural cables to prevent corrosion and physical tampering. Chemical Manufacturing: Used as a splash-guard pipe to contain potential leaks from primary hazardous fluid lines in overhead racks.
