壳体板

Shell plate is the cylindrical or curved structural component that forms the main body of evaporators and pressure vessels, designed to contain fluids under pressure and temperature.

技术定义与适配语境
典型 壳体板 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A shell plate is a critical structural element in evaporator bodies and pressure vessels, typically fabricated from rolled metal sheets and welded to form cylindrical or spherical sections. It serves as the primary containment barrier for process fluids, withstanding internal pressure, thermal stresses, and corrosion while maintaining structural integrity. In evaporators, shell plates provide the housing for heat exchange tubes and separation chambers, with thickness and material selection determined by design pressure, temperature, fluid properties, and regulatory requirements.

定义
A shell plate is a critical structural element in evaporator bodies and pressure vessels, typically fabricated from rolled metal sheets and welded to form cylindrical or spherical sections. It serves as the primary containment barrier for process fluids, withstanding internal pressure, thermal stresses, and corrosion while maintaining structural integrity. In evaporators, shell plates provide the housing for heat exchange tubes and separation chambers, with thickness and material selection determined by design pressure, temperature, fluid properties, and regulatory requirements.
工作原理
Shell plates function as pressure-retaining components that distribute mechanical stresses uniformly through their curved geometry. They operate by containing internal pressure forces through hoop stress (circumferential) and longitudinal stress (axial) distribution, with the curved shape providing optimal strength-to-weight ratio. In evaporators, shell plates create the sealed environment where liquid evaporation occurs through heat transfer from internal tubes or coils, while preventing fluid leakage and maintaining pressure differentials.

常见问题

What determines shell plate thickness in evaporators?

Thickness is calculated per ASME Section VIII based on design pressure, temperature, material allowable stress, corrosion allowance, and joint efficiency factors.

Can shell plates be repaired after installation?

Limited repairs are possible following ASME NBIC guidelines with proper welding procedures, NDT verification, and engineering approval for pressure boundary integrity.
