All ratings listed for types K, L, M, DWV and refrigeration service tube in the preceding charts are calculated for tube in the annealed condition. These values should be used when soldering, brazing or welding is employed for joining components in a system. While the ratings for hard drawn tube are substantially higher, they should only be used for systems using properly designed flare or compression mechanical joints, since joining by any heating process might anneal (soften) the tube. In designing a system, careful consideration should also be given to joint ratings as well as those of the components.

COPPER TUBE AND SOLDER TYPE FITTINGS 1. Cut tube square with the cutter or fine hack saw (32 tooth blade is recommended). Remove Burr. 2. Clean outside end of copper tube thoroughly with sand cloth or sandpaper equal depth of fitting. Leave no dark spots. 3. Clean inside of fitting carefully to tube stop with wire brush. Note: Sand cloth or sandpaper may also be used. 4. Using a brush, apply light uniform coat of soldering flux to the outside of the tube and inside of the fitting.
1. Cut tube to length & remove burr with file or scraper.
2. Clean outside of tube with sandpaper or sand cloth.
3. Clean inside of fitting with wire brush, sand cloth or sandpaper.
5. Slip tube into fitting to tube stop. Turn tube back and forth once or twice to distribute flux evenly. 6. Apply heat uniformly around the fitting with torch. When solder melts upon contact with heated fitting, the proper soldering temperature has been reached. Remove flame and feed solder slightly off center at the bottom of the joint. Proceed across the bottom of the fitting and up to the top center position. Return to the starting point, and then proceed up the incomplete side to the top, again, overlapping the solder metal. Wipe off surplus solder with a piece of cloth. CAUTION: No not overheat the joint or direct the flame into the face of the fitting cup. Overheating could burn the flux, which will destroy its effectiveness and the solder will not enter the joint properly.
4. Apply flux thoroughly to inside of fitting.
5. Apply flux thoroughly to outside of tube - assemble tube and fitting.
6. Apply heat with torch. When solder melts upon contact with heated fitting, the proper temp for soldering has been reached. Remove flame & feed solder to the joint at one or two points until a ring of solder appears at the end of the fitting.

If inhaled, get fresh air and seek medical attention if ill feelings persist. KEEP OUT OF REACH OF CHILDREN. Refer to material safety data sheet for more information. For emergency first aid help, call 1-877-740-5015. PHYSICAL/CHEMICAL PROPERTIES Alloy composition Tin, Copper, Bismuth, Silver Appearance Silver Solid Wire Melting Range 420° F to 460° F DIRECTIONS FOR USE Cut the pipe to the exact length required using a tube cutter. Be sure the pipe is cut square. Remove all burrs on the inside and outside of the pipe surface with a reamer tool. Remove all oil, grease and oxide corrosion from the surface of the piping to be joined. Surfaces may be cleaned with abrasive sandcloth or a steel wire brush. The joining surfaces must be clean before soldering. Apply a small amount of approved flux to the pipe and fitting surface. Proper fluxing is important because the flux promotes the flow of the filler metal. Insert the pipe end into the fitting. Heat the joint area, using caution not to overheat the joint. Feed the solder wire into the joint. When the solder wire has drawn around the entire joint, remove the heat. When soldering process is complete, allow the joint to cool undisturbed. When joint is cool, remove any flux residual with a damp cloth. Safe Flo Silver Lead Free Solder is not recommended for use on aluminum.

Fitting Summary Data Sheet

ven with all the advances in technology today, the wholly welded piping system has for decades remained the best choice for use in high pressure and high temperature application. Many piping jobs in schools, industrial plants, refineries and factories have benefited from the inherent advantages of a completely welded system. It becomes a closed container joining pipes, valves, fittings, and flanges. A welded joint actually becomes part of the pipe, minimizing leak potential. This provides greater margins of safety, especially under conditions of high internal pressures. Additionally, welding fittings form a continuous metal structure with the pipe, adding forged-in strength to any piping system. Furthermore, smooth forged fittings simplify insulation and take up less space.
ASTM A 234 Scope This standard covers wrought carbon steel fittings of seamless and welded construction which are manufactured to the dimensional specifications of ASME B16.9 and B16.28. These fittings are primarily for use in pressure piping and in pressure vessel fabrication for service at moderate and elevated temperatures.
Materials The starting material for fittings shall consist of killed steel, forgings, bars, plates, seamless or fusion-welded tubular products with filler metal added and shall conform to the the chemical requirements of ASTM A 234. Unless otherwise specified, carbon steel plates may be either coarse grain or fine grain practice.
Manufacture Forging or shaping operations are performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, machining, or by a combination of two or more of these operations. The forming process shall be applied so that it will not produce injurious imperfections in the fittings.
Heat Treatment Hot-formed WPB fittings, upon which the final forming operation is completed at a temperature above 1150ºF and below 1800ºF, need not be heat treated. Cold-Formed WPB fittings, upon which the final forming operation is completed at a temperature below 1150ºF, shall be normalized, or shall be stress relieved at 1100ºF to 1275ºF.
