Bleed Rings – Reliable Pressure Relief & Drainage Solutions
Bleed Rings are specially designed components installed between flanges to safely relieve excess pressure, drain trapped fluids, or connect instrumentation without dismantling the entire pipeline. They provide a practical and efficient solution for maintenance, testing, and monitoring in pressurized systems.
Key Features & Advantages
- Material Options – Available in Stainless Steel, Carbon Steel, Inconel, and other corrosion-resistant alloys.
- Robust Construction – Manufactured from forged metal for superior strength and durability.
- Standard Compatibility – Designed to fit between standard flanges with 1/2-inch or 3/4-inch tapping options.
- Multi-Purpose Use – Suitable for pressure venting, fluid drainage, and instrument mounting.
- Cost-Effective Installation – Easy to install and often preferred as an economical alternative to specialized flange assemblies.
