Fusion-welding is possible for different metals whose properties are similarsuch as titanium and zirconium; howeverthe weld will have unpredictable properties and will be significantly less ductile and less corrosion resistant than either of the base materials. The outer tube can be welded to the stainless steel tube sheet. These techniques provide high-integrity metallurgical bonds between dissimilar metals that are suited to the urea stripper. Alsostainless steels typically do not tolerate reducing acid conditions because the passive film contains oxygen and hydroxide ions. The tube consists of a corrosion-resistant zirconium liner that has been fitted mechanically into an outer tube of stainless steel. In urea servicezirconium has proven to be one of the most durable materials available and zirconium components have outlasted the surrounding equipment.

Howeverwelding dissimilar metals is notoriously troublesome. The resulting bond is surprisingly strong and ductile and virtually no alloying of the materials occurs. The metallurgical bonds provided by OmegaBond technology are very strong and ductile and maintain their integrity during fabrication operations. The outer tube can be welded to the stainless steel tube sheet. Howeverthe stainless steel still requires good oxygen distribution inside the HP stripper to ensure a satisfactory protective film.
