How does the double - wall structure of a self bunded tank work

2025-08-29 Leave a message

Double-Wall Tank Structure

Integrated Safety and Efficiency Design

The double-wall structure consists of two distinct walls with an interstitial space between them, providing comprehensive protection and functionality.

Core Components

  • Inner Wall: Directly contains the stored liquid under pressure
  • Outer Wall: Serves as a protective barrier and secondary containment
  • Interstitial Space: Critical gap between walls enabling key safety functions

Primary Functions

  • Leak Containment: Prevents environmental contamination by trapping leaks in the interstitial space
  • Early Detection: Allows monitoring systems to identify issues before they escalate
  • Thermal Stability: Insulation materials buffer against external temperature changes
  • Enhanced Durability: Outer wall protects against physical impacts and weather elements
  • Pressure Distribution: Dual-wall design reduces strain on individual components

This integrated system addresses multiple storage risks simultaneously, creating a safe, durable, and efficient solution for long-term liquid containment.
