For higher pressures, or where greater joint strength is required, 95-5 tin-antimony solder and alloys E and HB can be used. The 50-50 tin-lead solder is suitable for moderate pressures and temperatures. Rated internal working pressures for solder joints made with copper tube using 50-50 tin-lead solder (ASTM B32 Alloy Sn50), 95-5 tin-antimony solder (ASTM B32 Alloy Sb5), and several lead-free solders (ASTM B32 Alloy E and Alloy HB) are listed in Tables 14.3a-e. In such cases, the stresses caused by a temperature change are usually insignificant. However, this may not be necessary when a tube length is short or when an expansion loop is used in a long tube run. Consideration should also be given to the stresses on joints caused by thermal expansion and contraction. The selection of a solder depends primarily on the operating pressure and temperature of the system. Flux acts as a wetting agent and, when properly applied, permits uniform spreading of the molten solder over the surfaces to be joined. Warranties by the manufacturer are the sole responsibility of the provider.Soldered joints depend on capillary action drawing free-flowing molten solder into the gap between the fitting and the tube.
