TESCOM AGI BR Series packaged flushing ring solution

Emerson has announced the TESCOM AGI BR Series Flushing Ring, a packaged solution for flushing and bleeding applications in petroleum refineries, biofuel refineries and petrochemical facilities. By providing a complete, modular valve assembly with a single part number, the AGI BR Series flushing ring is designed to streamline ordering and allow for easy reordering with user-specific test requirements. Both traditional BRS ‘sandwich’ and BRW ‘wafer’ style rings are available, as well as the BR7 ‘integrated bonnet’ design, which includes the bleed/flushing functions in the flange ring itself.

Most flushing ring devices are sold as separate components and assembled in the field. This often involves on-site welding and non-destructive examination (NDE) requirements such as pressure testing, positive material identification (PMI), dye-penetrant and radiography. In comparison, the AGI flushing ring includes valve assembly, welding, painting and testing in one comprehensive, compact package.

The AGI flushing ring meets piping and instrument class requirements according to the ASME B16.34 standard and is suitable for installation in processes requiring flushing of residue in front of diaphragm seals such as distillation towers, hydrotreaters, coking towers, reactors and separators. Fugitive emissions bonnets and ball valves that follow ISO 15848-1 and 2 are also available.

The TESCOM AGI flushing ring features flanged connections that are available in a range of sizes from 1 to 6″, pressure class ratings from 150# ANSI to 2,500# ANSI, and temperature range options from -192°C to 538°C. Additionally, Emerson can provide custom variations and NDE testing to meet specific project requirements.
