Cylindrical or conical section forming the main body of a pressure vessel, designed to contain internal pressure and transfer loads.
A shell section is a fundamental structural component of a pressure vessel body, typically cylindrical or conical in shape, that provides the primary containment for internal pressure. It is engineered to withstand both internal pressure loads and external forces while maintaining structural integrity. The section's geometry, thickness, and material properties are calculated based on design pressure, temperature, and safety factors according to pressure vessel codes. Shell sections are manufactured through processes like rolling and welding plate materials, with careful attention to dimensional accuracy, weld quality, and surface finish to ensure leak-tight performance and corrosion resistance.

Shell sections are typically cylindrical or conical segments that form the straight portion of a pressure vessel, while dished ends (heads) are curved closures at the vessel ends. Shell sections primarily resist hoop stress from internal pressure, whereas dished ends experience more complex stress patterns.
Shell thickness is calculated using formulas from pressure vessel codes (like ASME Section VIII) considering design pressure, material allowable stress, joint efficiency, corrosion allowance, and temperature. The minimum required thickness ensures the shell can withstand internal pressure without exceeding material stress limits.
Common inspection methods include visual examination, dimensional verification, ultrasonic thickness testing, radiographic testing of welds, magnetic particle testing, dye penetrant testing, and hydrostatic pressure testing to ensure integrity and compliance with standards.
