What is the NPT (National Pipe Thread)?
National Pipe Thread Taper is the most popular type of thread used in the United States and Canada for tapered threads used on threaded pipes and fittings. Unlike straight threads that you find on a bolt, a taper thread pulls tight and therefore makes a fluid-tight seal.
Malleable cast iron like ductile iron possesses considerable ductility and toughness because of its combination of nodular graphite and low carbon metallic matrix. However the nodules are not truly spherical as they are in ductile iron but are irregularly shaped aggregates.
Malleable cast iron and ductile iron are used for some of the applications in which ductility and toughness are important. In many cases, the choice between malleable and ductile iron is based on economy or availability rather than on properties. In certain applications, however, malleable cast iron has a distinct advantage. It is preferred for thin section castings as given below.
