Clad metal, two or more dissimilar metals bonded together, is an important material for many of the world’s essential industries. overlay steel plate
End-user requirements determine which metals or alloys to use. A common example is providing corrosion- or abrasion-resistant equipment while maintaining the strength and ease of fabrication associated with traditional carbon steels. In this case, designing with clad equipment offers significant heat-transfer benefits compared to equipment fabricated with a solid alloy. This is especially true with jacketed reaction vessels, where the time to reach a reaction temperature is a critical factor in the production of a product.
As a trusted fabricator for critical process equipment and vessels for industries of all kinds, Enerfab has extensive experience designing and building to customers’ unique requirements. When clad metals are called for, Enerfab relies on NobelClad.
NobelClad combines metallurgical and welding expertise to join more than 260 compatible and non-compatible metals by the DetaClad™ process, offering the largest collection of clad metal products in the world. The key to Enerfab’s success in fabricating NobelClad’s products is a proprietary process that eliminates the requirement to strip back the cladder from the weld joint while achieving the proper chemistry required for corrosion resistance. The compliant weld in the base metal is performed without the requirement for additional, complex production steps.
Benefits of clad for pressure vessels
The functional benefits of using certified DetaClad™ plates are many. From design flexibility to equipment reliability, end-users ultimately achieve lower operational and maintenance costs.
With explosion clad, where metals are bonded using explosives, direct welds are possible without removing the alloy first, saving fabricators time and money. Explosion cladding is particularly useful for manufacturing distillation columns for petroleum products like kerosene, heavy fuel oil and propane. The trays and other internal features can be welded directly to columns. When selecting a fabricator and clad vendor, quality systems and technical experience are critical. And the welding engineers and technicians at Enerfab have extensive experience in directly attaching components to explosion-clad metals.
The high-pressure and high-temperature environments combined with the variety of chemicals in pressure vessels make large clad plates indispensable to fabricators in the O&G industry. Pressure vessels for O&G are commonly designed as cylinders with hemispherical and/or dished heads. NobelClad’s large plates reduce costs by allowing the manufacture of seamless, one-piece heads, which use an average of 15-to-20 % less material and have fewer welds, making them more reliable and safer than traditional crown and petal applications. Additionally, in some of the most extreme processing environments, end-users rely on reactive metal cladding for corrosion resistance to reduce unplanned downtime and unscheduled maintenance. NobelClad’s large titanium- and zirconium-clad plates offer a more affordable, reliable solution than other alternatives.
The bond strength produced by the DetaClad™ process is another benefit during the head-forming process. The strength of NobelClad’s explosive bonded clad makes it less likely that the cladder and backer will separate during the dishing and flanging processes associated with forming a head.
A history of successful projects

Economics of clad: Best practices of designing, fabricating and ordering clad
When it comes to designing, fabricating and ordering clad plates, the nuances and requirements are many. No clad vendor or fabricator is the same, and vetting those options can seem like a daunting task. By choosing a trusted clad-metals partner and fabricator expert to guide you throughout the design process, you can avoid the pitfalls and protect your investment.
To help you better understand all the possibilities, Enerfab and NobelClad can host technical seminars with your team focused on the economics of clad and best practices for designing with clad materials, ordering those materials, and then successfully fabricating the finished product.
When we receive an inquiry at Enerfab, we always look to provide the best value for our clients. As a rule of thumb, once the pressure vessel’s calculations show an inch or greater wall thickness, our estimators analyze the use of the clad plate.
