Reactive metals such as titanium and zirconium are long trusted by chemical plant owners, operators, and licensors for corrosion-resistance in demanding high-pressure and high-temperature piping systems. However, these metals are costly and may have design and reliability limitations including toughness and crack growth concerns when used in solid form. Cladding titanium or zirconium alloys to the interior of carbon steel or stainless-steel pipe with very well characterized mechanical properties offers the anti-corrosion benefits of reactive metals at a significantly reduced cost.

NobelClad has developed a unique cladding process that greatly exceeds the loose-lining process, allowing for a substantially higher mechanical integrity across the entire piping system. The product is marketed as DetaPipe™ and can be formed into pipes and elbows and soon into tees, ranging from 3-inch NPS (80 DN) to 30-inch NPS (750 DN). The new pipe adheres to the ASME B31.3 standards and withstands pressure ratings from full vacuum to well above 70 bar (1000 psi). Pipe spools have several connection types such as ANSI B16.5 or ANSI B16.47 flanges, including other commercially available energized seal options.

During this presentation, the authors will present the general mechanical properties and attributes of this clad pipe product, and how it offsets the concerns of using solid refractory metals when handling acids such as acetic acid, acrylic acid, nitric acid, sulfuric acid, urea, and many more.
