INDUSTRY COMPONENT

Tank Shell

Tank shell is the primary structural component of a melt surge tank, designed to contain molten materials under pressure and temperature variations.

Component Specifications

Definition
The tank shell is a cylindrical or spherical pressure vessel component that forms the main containment structure of a melt surge tank. It is engineered to withstand internal pressures from molten materials, thermal stresses from temperature fluctuations, and external mechanical loads. The shell provides structural integrity, prevents material leakage, and maintains process stability in industrial melting operations.
Working Principle
The tank shell operates on pressure vessel principles, distributing internal stresses uniformly through its curved geometry. It contains molten materials while resisting deformation through material strength and structural design. Thermal expansion is managed through material selection and design features to prevent failure under cyclic heating and cooling conditions.
Materials
Stainless steel (AISI 316L, 304L), carbon steel (SA-516 Gr.70), alloy steels with high-temperature resistance. Thickness: 10-50mm depending on pressure rating. Surface finish: Ra ≤ 3.2μm for corrosion resistance.
Technical Parameters
  • Height 1200-5000mm
  • Diameter 800-3000mm
  • Surface Area 5-50 m²
