Our bleed and flush rings can be modified for your specific application or process line requirements
Mac-Weld flush rings are available in variety of bores including concentric, eccentric, reducing concentric and reducing eccentric style.
Our Flush Ring design is made to accept all flanged pressure transmitters on one side and a standard ANSI flange on the other side in all sizes. An example of this would be as follows; 2” thick can come with two different ANSI sizes on each side allowing for example a 2” 150# process to fit with a 3” 150# level transmitter.
Mac-Weld bleed rings are manufactured in house as well, and can be modified for your specific application or process line requirements. Bleed rings may also be referred to as calibration rings or drip rings, but they all do the same thing.
Face Styles
- Flat Face
- Raised Face
- Ring Type Joint (RTJ)
Exotic Materials & Coatings for Bleed and Flush Rings
We have experience manufacturing bleed and flush rings in a wide range of exotic and corrosion-resistant materials to suit demanding service conditions. Materials used include Super Duplex, Chrome-Moly, Hastelloy, 304/304L & 316/316L Stainless Steels, Carbon Steel , Monel, Inconel, Titanium, and Kynar just to name a few.
To further enhance performance and service life, available coatings and surface treatments include PTFE coatings for chemical resistance, electroless nickel plating (ENP), zinc or phosphate coatings, passivation, and specialized corrosion- or wear-resistant coatings as required by the application.
All rings are quality checked and tested to code, prior to being shipped
Precision | Quality | On-time Delivery
Mac-Weld manufacturers all bleed and flush rings, with over 40 years experience manufacturing the hardware to the temperature, flow and pressure industries. These rings are designed to mount between the flanged process connection and the diaphragm seal, which then allow easy access for on site calibration, venting & purging.
