Overview
Product Overview
The Floating Reducer Hose (Single Carcass) by Quanyi Rubber is a specialized marine oil and fluid transfer hose designed to connect pipeline systems with differing inner diameters while maintaining self-buoyant surface positioning. Specifically engineered for demanding offshore environments—such as Single Point Mooring (SPM) facilities, FPSO offshore loading terminals, and heavy-duty marine dredging operations—this hose eliminates the need for external buoy attachment.
Manufactured with a high-grade synthetic rubber inner lining tailored for crude oil, liquid hydrocarbons, refined fuels, or abrasive slurry, the tube provides superior oil and wear resistance. The structural carcass is reinforced with multiple plies of high-tenacity tire cord and helical steel wire, offering high tensile strength, kink resistance, and full vacuum capability.
The floating carcass incorporates a specialized closed-cell foam layer that absorbs zero water, ensuring persistent reserve buoyancy even if the tough outer cover suffers localized surface damage. Wrapped in an age-, ozone-, UV-, and seawater-resistant EPDM outer rubber cover, the hose withstands severe wave motion, constant rubbing, and marine environmental exposure. Equipped with integrated built-in steel flanges, Quanyi floating reducer hoses ensure maximum operational safety and seamless diameter transition in offshore liquid logistics.
