ADVANTAGES & QUALITY FEEDBACK OF BRAZING RING IN THE COPPER TUBE RECEIVED FROM VARIOUS CLIENTS

    1. The result of the testing was very nice enhanced quality for workmanship, installation & execution of Brazing pipes together in a shorter time span with great craftsmanship in a neat and tidy finish.

    1. By this we can execute our Brazing work faster compared to the conventional practice of doing Brazing with Brazing Rod in one hand & torch in the other.

    1. Instead of occupying two hands while doing Brazing. We could get it done with the one hand more skillfully and with better workmanship.

    1. Skill level required is nominal and hence any one (even unskilled brazer) can do leak proof joints with basic knowledge of handling torches.

  1. It becomes more Cost effective, as only required brazing filler metal is used and no excess material is wasted anywhere.

With continuous research and development taking place at MANDEV TUBES, we have been able to innovate and develop the ONE END EXPANDED COPPER TUBE WITH INNER BRAZING RING. The unique design helps eliminate a coupling cost, while joining the tubes. Not only it reduces costs by up-to 78% comparing to regular tube installation cost, it prevents leakage by 50% and also helps in saving 100% of your BRAZING COST.

Further as the tubes are of half hard temper, one can eliminate elbow cost, while joining the two tubes. Due to this uniqueness, it reduces costs by up-to 100% compared to regular installation and also prevents leakage by 100%. These tubes can be easily bent with the help of Mechanical bender.
