Bleed & Flush Rings

Bleed & Flush Rings

Bleed and flush rings are circular, flanged components installed between standard process flanges and instrumentation such as diaphragm seals or pressure transmitters. These rings include one or more threaded ports that provide access to the process media for flushing, venting, draining, or sampling. Constructed from durable, corrosion-resistant materials like stainless steel, they offer a secure and standardized interface for fluid system maintenance and monitoring.

Bleed rings are primarily used to relieve pressure, drain trapped fluids, or safely vent gases from piping systems. This is especially important during maintenance or shutdown procedures, as they allow for controlled depressurization without dismantling the pipeline. Flush rings, on the other hand, are used to clean the process side of a diaphragm seal by introducing a flushing fluid. This prevents the buildup of process material that could affect measurement accuracy or damage sensitive instrumentation.

Both bleed and flush rings enhance safety, reliability, and performance in fluid handling systems. They allow maintenance personnel to perform critical operations such as line purging, calibration, and pressure equalization with minimal disruption. Their use helps maintain measurement integrity, reduce downtime, and extend the life of connected equipment.

These rings are commonly used across general industries, including oil and gas, chemical processing, power generation, water treatment, food and beverage, and pharmaceuticals. They are particularly beneficial in applications involving viscous, corrosive, or solid-laden fluids, where keeping diaphragm seals clean and relieving trapped pressure are essential for efficient and safe operation.
