Manufacturer profiles associated with Shell.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
The shell provides pressure containment for the liquid-vapor mixture in distillation systems, maintaining system pressure for efficient separation while housing internal components and ensuring structural integrity.
Shell thickness is calculated using ASME BPVC Section VIII formulas considering design pressure, temperature, material properties, corrosion allowance, and weld joint efficiency, typically resulting in 6-25mm thickness for standard applications.
Carbon steel (SA-516) for non-corrosive services, stainless steel (304/316) for corrosive environments, and clad materials for cost-effective corrosion resistance in chemical processing applications.
