Clad Materials (Stainless Steel Clad, Titanium Clad) Polyurethane Insulated Pressure Vessels
Clad material polyurethane insulated pressure vessels combine the corrosion resistance of specialty alloy cladding with the structural strength and economy of carbon steel backing, along with the thermal efficiency of polyurethane foam insulation. These vessels feature metallurgically bonded or weld-overlay cladding to provide optimal performance at reduced cost compared to solid alloy construction.
Why Choose Clad Materials (Stainless Steel Clad, Titanium Clad) for Polyurethane Insulated Pressure Vessels?
Clad construction is essential for large pressure vessels where solid alloy construction would be prohibitively expensive, yet corrosion resistance requirements exceed carbon steel capabilities. The clad approach provides full alloy corrosion resistance at the process-wetted surfaces while utilizing economical carbon steel for structural strength.

Clad Materials (Stainless Steel Clad, Titanium Clad) Polyurethane Insulated Pressure Vessel FAQs
What cladding methods are available for pressure vessels?
Common cladding methods include roll bonding (hot rolling layers together), explosion bonding (using explosive force to bond layers), and weld overlay (depositing alloy by welding). Roll bonding is most economical for large quantities. Explosion bonding provides superior bond quality. Weld overlay offers flexibility for complex geometries and repair applications.
How are clad vessels inspected for bond integrity?
Clad bond integrity is verified through ultrasonic testing that detects unbonded areas between the clad and backing material. Shear strength testing verifies metallurgical bond quality on sample coupons. Visual examination ensures complete cladding coverage. All inspection is performed to ASME requirements.
What design considerations apply to clad vessel nozzles?
Nozzles in clad vessels can be fabricated from solid alloy, clad material, or carbon steel with weld overlay. The method depends on nozzle size, service conditions, and economics. Weld procedures ensure proper joining of dissimilar materials at the clad interface while maintaining full corrosion protection.
