DVVV and refrigeration service tube in the preceding chartsare calculated for tube inthe <br />annealed condition. These values should be used when soldering, brazing or welding is employed forjoining components in <br />a system. While the: ratings for hard drawn tube are substantially higher, they should only be used for systems using properly <br />designed flare or compression mechanical joints, since joining by any heating process might anneal (soften) the tube. <br />In designing a system, careful consideration should also be given to joint ratings as well as those of the components <br />A BRAND OF MUEHAilR INDUSTRIESA <br />
