FAQ
Q1: What fluids is the Uni OSD hose compatible with?
A: This hose is designed for a wide range of hydrocarbons, including crude oil, diesel, lubricants, biofuels, and oil-based sludge. It is also suitable for many chemicals and abrasive slurries.
Q2: How does the price compare to other oil transfer hoses?
A: We offer highly competitive composite hose price points due to our integrated manufacturing and efficient supply chain. Despite this, every hose meets international quality and safety standards.
Q3: What does “OSD” stand for?
A: OSD refers to Oil, Sludge, and Discharge – indicating the hose’s suitability for transferring petroleum products, sludge materials, and discharge operations.
Q4: Can I get custom end fittings and lengths?
A: Yes, we provide custom lengths and a wide choice of end fittings (flanges, camlocks, etc.) to match your specific operational requirements.
Q5: Is the hose suitable for offshore use?
A: Absolutely. Its construction meets the demands of marine and offshore environments, including resistance to seawater, UV exposure, and fluctuating pressures.
