Fail-Safe Transfer Line for Hazardous Fluids

摘要

The design principles, development, laboratory testing, fabrication and field testing of a fail-safe transfer line for hazardous liquids are described. The system provides a 2-inch-ID flexible hose line for off-loading tank cars or trucks and detects leaks by monitoring flow inventory with corrosion-resistant, turbine-type flow meters at the inlet and outlet ends. Reliable shutdown of the line at leak rates as low as 1% of flow is achieved.
