DURA-PLATE
®
Corrosion-Resistant Fittings have a T&B plating process
that provides excellent corrosion resistance on threaded steel and
malleable iron fittings for use in harsh environments.
DURA-PLATE
®
Corrosion-Resistant Fittings utilize an electro-plating
process that ensures a uniform thickness of protective material over
the entire part. Conventional hot dip coatings deposit an uncontrolled
buildup of material on the part, especially in threaded areas. This
excess buildup must be removed to enable mating parts to function.
The process of removing this buildup in the threads in turn damages
the coating and compromises the effectiveness of the protection.
An additional drawback of hot dip coating is that the lower ductility
of the alloyed interface layer that is formed during the hot dip
process can cause spalling if the item is deformed after coating.
In addition to the uniformity of the coating, the distinctive gold color
of the plating enables immediate recognition that the part has been
prepared for exposure to harsh environments and confirms the extra
protection by visual inspection.

Corrosion-Resistant Fittings have been subjected to
salt spray tests conducted according to ASTM Specification B-117.
The results of Corrosion-Resistant Fittings tests, along with galvanized
parts, appears below:
