Rings

P&I designs and manufactures brazing rings to customer-defined specifications. Our rings help provide accurate braze volume control and improve consistency during the joining process yielding a higher-quality braze joint while reducing alloy consumption. Our manufacturing capabilities allow us to produce many ring types ensuring more efficient and higher-quality braze joints.

Segment Braze Ring

ID Band Braze Ring

A ring made from flattened wire. Often used to increase volume of preform where increased wire diameter won't work. Also used to place 1 preform instead of 2. ID Typical dimensions: 0.500 ID X 0.020 X 0.050 BAND-RING X 0.015 Max Gap.

Band Braze Ring

Edgewound

A ring made from flattened wire, but with the smaller surface on the ID & OD. Can be a cheaper alternative to a washer. Edgewounds have a slight helix. Typical dimension: 0.500 ID X 0.020 X 0.050 EDGEWOUND X 0.015 Max Gap.
