Ward Class 150 Malleable Iron Fittings are made with the
most sophisticated metallurgical and processing controls available.
Iron samples are continuously analyzed using spectroscopy
to conform the material quality. This sophisticated chemical
analysis is complemented by rigorous quality control of incoming
raw materials and iron processing. The final casting produced by
this detailed attention to quality is a close-grained, high strength,
non-porous iron.
Quality iron is the starting point for Ward fittings. From this iron,
accurate threads are machined that comply with the precise
standards developed by the Amerian Society of Mechanical
Engineers (ASME) and published as an American National
Standard. The threads have an accurate form, thread length and
straightness to allow them to easily engage threaded pipe. In
addition, Ward fittings have a chamfered opening to allow faster
and easier pipe engagement. This feature also protects the fitting
threads from damage during handling.
All Ward black & galvanized Class 150 Malleable Iron Fittings
having outlets ranging from 1/2€ through 4€ are air tested at 80
psig. This test is part of a constant program to maintain the
highest quality fittings available.
