Component Specifications

Definition
The tank body or shell is the main cylindrical or spherical structural element of a chemical storage tank, engineered to withstand internal pressures, external loads, and environmental factors while preventing leaks and contamination. It serves as the primary barrier between stored chemicals and the external environment, requiring precise engineering for material compatibility, corrosion resistance, and structural integrity.
Working Principle
Operates as a pressure-retaining boundary that contains chemical substances through balanced mechanical design. The shell distributes internal pressure stresses evenly across its surface area, utilizing principles of thin-walled pressure vessel theory (hoop stress and longitudinal stress calculations) to maintain structural stability while preventing deformation or rupture.
Materials
Stainless steel (AISI 304/316/L), carbon steel with corrosion-resistant linings (epoxy, rubber, glass-flake), fiber-reinforced plastic (FRP), polyethylene (HDPE/XLPE), or specialized alloys (Hastelloy, Inconel) depending on chemical compatibility requirements.
Technical Parameters
  • Capacity 1,000-100,000 liters
  • Diameter 1-10 meters
  • Wall Thickness 6-50 mm
  • Design Pressure Atmospheric to 10 bar
  • Design Temperature -40°C to 200°C
  • Corrosion Allowance 1-3 mm
Standards
ISO 28300, ASME BPVC Section VIII, DIN 28018, EN 14015
