Figures 5.6 and 5.7 show that the addition of 0.5 % molybdenum to ferritic Ductile Iron produces significant increases in creep and stress rupture strengths,resulting in high temperature properties that are comparable to those of a cast steel containing 0.2 % carbon and 0.6 % manganese.Ductile Iron Pipe Standards and Suggested Specifications ANSI/AWWA C151/A21.51 American National Standard for Ductile-Iron Pipe,Centrifugally Cast,for Water; ANSI/AWWA C153/A21.53 American National Standard for Ductile-Iron Compact Fittings,3-inch through 24-inch and 54-inch through 64-inch,for Water ServiceDuctile Iron Valve Flomatic ValvesFlomatics ductile iron valve series 80DI are one of the most popular valves in the water well industry today.They are specifically designed for use with submersible pumps or other applications where it is necessary for the check valve to be installed in the well casing.The 80DI series valves will provide excellent service in any application where a conventional check valve is recommended and is
Ductile iron is a kind of high-strength cast iron material developed in the 1950s.Its comprehensive performance is close to that of steel.Based on its excellent performance,ductile iron has been successfully used to cast some parts with complex stress,high strength,toughness and wear resistance.Ductile Iron Water Mains - ConstructionMentor.netA good rule of thumb for ductile iron pipe services is that 5/8,¾,and 1 taps can be made as direct taps,anything larger will often require a tapping saddle.Anything larger than 2 however should utilize a tapping sleeve.Thrust blocking is almost always required when installing ductile iron pipe and fittings.Ductile-Iron Pipe and Fittings - American Water Works The use of cast-iron pipe was introduced in the United States in the early 1800s.Since that time,various other piping materials have been offered for water distribu-tion.However,waterworks engineers continued to use cast iron until ductile iron,a stronger and equally durable piping material,became available.1.1.2 Development of Joints
