Brazing Ends: These ends are available on brass valves. The ends have a special* shape to facilitate use of brazing alloys. These valveB are used for higher tempera tures than solder end valves. : 4.

The brass used in valves is similar to that used in brass pipe and contains some tin and lead as well as copper and zinc. : Table 11.

A flaring tool flares the tube end, and a ring nut pulls the flared tubing up against a seat on the valve. This makes a lap joint. 6. Hub Ends: Generally used for water supply and sewage piping. This type joint is used with cast iron pipe. The joint is a socket type made by inserting the pipe in the hub, then caulking with oakum. After caulking, the joint is sealed with molten lead. Valves are made of brass, iron, steel, and to some extent malleable iron. 1 12 .3 14 15 16 17 18 19 20 Ring Joint. Nominal , Pipe Size Center to End, 45-Deg Elbow EK Long .

Cast iron is not suitable for service (above 450 F). Malleable iron, which is a cast iron heat treated to provide some ductilJty, is used to some extent, primarily in place of cast iron. Steel is used either in the cast or forged state. For corrosive service, alloy and stainless steel are used. Steel is used for high temperature--high
