| DURA-PLATE® Finish — Corrosion-Resistant Finish Protects Fittings in Harsh Environments | |||||||||||||||||||||||||||||||||||
| 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. DURA-PLATE® 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: 500- | |||||||||||||||||||||||||||||||||||
