Make Brazed Joints Better, Faster, and More Reliable

When using copper fittings that are designed for soldering, such as those made to ASME B16.22 or MSS SP-73 standards, only partially inserting the tube into the fitting is necessary as long as the joint is going to be brazed instead. The full insertion of the tube is not actually a very good idea when brazing solder-joint fittings because it wastes additional time and resources. The Brazing Dimpler® has even been permitted for use with medical gas piping under the 2012 edition of NFPA 99, published by the National Fire Protection Association.  In the section regarding assembling and heating brazed joints, the NFPA 99 specifies that, "Tube ends shall be inserted into the socket, either fully or to a mechanically limited depth that is not less than the minimum cup depth (overlap) specified by ANSI/ASME B16.50, Wrought Copper and Copper Alloy Braze-Joint Pressure Fittings."

Brazing Dimpler® Corporation, located in Greensboro, North Carolina, has also been featured in several magazines and other publications that cater to the engineering community. "Conventional Wisdom: When Brazing Copper Tube Is Wrong" was published in PMEngineer (PME) in January, 2005. This article featured our specialized dimpler and explained it in the following ways:

• Improves Brazed Joint Quality
• Reduces the Cost of Making Brazed Joints by 50% over the MCAA Labor Estimating Manual
• Improves Long-Term Performance of Joints

• Simplifies Cutting and  Assembly
• Reduces Filler Metal  Consumption by 50%
• Makes it Easier for the Brazer to Make a Top-Quality Joint
