Applications
Marine
Durable, high-performance HDPE pipe is ideal for a wide range of marine applications.
Long product life. High-strength, leak-proof material and joints. Corrosion, abrasion and chemical resistance. With its unique set of high-performance properties, HDPE is the ideal solution for a very wide of marine applications.
The ISCO marine product line offers superior flotation and protection from impacts, corrosion, chemicals and marine organisms.
HDPE’s high weather resistance enables it to survive UV exposure and freeze/thaw cycles with no degradation. Fusion-welded joints and attachments assure problem-free performance through the long life of the solution.
Why HDPE excels in marine evironments.

Fully fused HDPE joints create a monolithic, leak-free pipeline—ideal for submerged, tidal, and corrosive saltwater applications.
HDPE’s naturally buoyant, lightweight properties simplify transport and installation on or over water, while supporting floating systems with ease.
Built to last with a 100-year design life, HDPE performs reliably in demanding marine environments with minimal maintenance.
Inert to saltwater, chemicals, and marine organisms—HDPE resists corrosion, biological fouling, and chemical attack unlike traditional materials.
Engineered for high-impact resistance and abrasion tolerance—ideal for dynamic marine settings with floating debris, wave action, or vessel contact.
Withstands sun, salt spray, and extreme temperature swings—offering stable performance through freeze/thaw cycles and prolonged UV exposure.
HDPE solutions for marine applications: extreme performance and versatility.
