Bleed Rings – (also called bleeder spacers, vent rings, test inserts, or drip rings) are an easy and effective way to access in-line flow and can be used to take samples, drain piping, and install valves and various instruments. They can also reduce or dispose of pressure before removing a flange through the use of valves or blind flanges. One of the most common applications are their use as an alternative to orifice flanges. This is because they are faster to fabricate, easier to install, and more cost-effective. Typical industry standard is 1-1/2” thick and drilled/tapped with a radial NPT or machined for a socket weld prep at any size (may effect thickness) and material grade of your preference. Bleed rings can have a serrated, smooth, or RTJ finish depending on the desired application; and each one is manufactured to the customers specifications for purchase only. As with our other specialty products, many variations exist. We take pride in our custom fabrication capabilities that guarantee your needs are met regardless of the particular application.
