DUCTILE IRON PIPE
Ductile Iron also differs from Gray Iron in that its graphite form is spheroidal, or nodular, instead of the flake form found in Gray Iron. This change in graphite form is accomplished by adding an inoculant, usually magnesium, to molten iron of …

THRUST RESTRAINT DESIGN FOR DUCTILE IRON PIPE
pe.mcwane.comDuctile Iron pipe and fittings are most often joined with push-on (Figure 1) or mechanical joints. Neither of these joints provides significant restraint against longitudinal separation other than the friction between the gasket and the plain end of the pipe or fitting.

In this manner, the mechanical properties are considerably improved. The strength increases, yield point improves and brittleness is reduced. Such castings can even ...
