Example text

When cool, clean off any remaining flux residue with a wet rag (Figure 26). Whenever possible, based on end use, completed systems should be flushed to remove excess flux and debris. Testing Test all completed assemblies for joint integrity. Follow the testing procedure prescribed by applicable codes governing the intended service. Strong, leak-tight brazed connections for copper tube may be made by brazing with filler metals which melt at temperatures in the range between 1100ºF and 1500ºF, as listed in Table 12, page 40.

FIGURE 9: Bending Using a Lever-Type Hand Bender (tool shown is appropriate for use with annealed tube only) 42 Soldered joints, with capillary fittings, are used in plumbing for water lines and for sanitary drainage. Brazed joints, with capillary fittings, are used where greater joint strength is required or where service temperatures are as high as 350°F. Brazing is preferred, and often required, for joints in refrigeration piping. Mechanical joints are used frequently for underground tubing, for joints where the use of heat is impractical and for joints that may have to be disconnected from time to time.

The flux requirement is usually 2 ounces per pound of solder. Cooling and Cleaning Allow the completed joint to cool naturally. Shock cooling with water may stress the joint. When cool, clean off any remaining flux residue with a wet rag (Figure 26). Whenever possible, based on end use, completed systems should be flushed to remove excess flux and debris. Testing Test all completed assemblies for joint integrity. Follow the testing procedure prescribed by applicable codes governing the intended service.
