Industry-Verified Manufacturing Data (2026)

Tank Shell

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Tank Shell used in the Fabricated Metal Product Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Tank Shell is characterized by the integration of Shell Plate and Longitudinal Seam. In industrial production environments, manufacturers listed on CNFX commonly emphasize Carbon Steel construction to support stable, high-cycle operation across diverse manufacturing scenarios.

The primary structural enclosure of an insulated storage tank that contains the stored material and provides pressure containment.

Product Specifications

Technical details and manufacturing context for Tank Shell

Definition
The tank shell is the main cylindrical or spherical body of an insulated storage tank that forms the primary containment barrier for liquids, gases, or bulk materials. It serves as the structural framework that withstands internal pressure, external loads, and environmental forces while maintaining the integrity of the stored contents. As part of an insulated storage tank system, the shell works in conjunction with insulation layers and protective coatings to maintain temperature stability and prevent heat transfer.
Working Principle
The tank shell functions as a pressure vessel that contains the stored material while resisting mechanical stresses from internal pressure, weight of contents, and external environmental factors. It maintains structural integrity through proper material selection, thickness design, and fabrication techniques, providing a sealed environment that prevents leakage and contamination.
Common Materials
Carbon Steel, Stainless Steel, Aluminum
Technical Parameters
  • Shell thickness and diameter specifications (mm) Customizable
Components / BOM
  • Shell Plate
    Individual curved steel plates that form the cylindrical or spherical shell sections
    Material: steel
  • Longitudinal Seam
    Welded joints running parallel to the tank's vertical axis connecting shell plates
    Material: weld material
  • Circumferential Seam
    Welded joints running around the tank's circumference connecting shell courses
    Material: weld material
  • Shell Reinforcement
    Additional structural elements like stiffeners or rings that provide extra support
    Material: steel
Engineering Reasoning
0-2.5 bar (gauge pressure)
Yield strength of 355 MPa for structural steel at 20°C
Design Rationale: Plastic deformation due to hoop stress exceeding material yield strength, calculated by σ_h = (P × D) / (2 × t) where P=internal pressure, D=tank diameter, t=shell thickness
Risk Mitigation (FMEA)
Trigger Corrosion rate exceeding 0.5 mm/year due to chloride-induced pitting
Mode: Wall thickness reduction below minimum design thickness of 6 mm
Strategy: Cathodic protection system with -850 mV vs. Cu/CuSO4 reference electrode potential
Trigger Thermal cycling between -20°C and 80°C at 3 cycles/day
Mode: Fatigue crack initiation at weld seams after 10^5 cycles
Strategy: Post-weld heat treatment at 600°C for 2 hours per ASME Section VIII requirements

  • Design pressure (bar)
  • Material compatibility with stored media

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Corrosion
Cause: Chemical attack from stored fluids, atmospheric exposure, or stray electrical currents leading to material degradation and thinning.
Fatigue cracking
Cause: Cyclic stresses from thermal expansion/contraction, fluid level changes, or mechanical vibrations causing crack initiation and propagation.
Maintenance Indicators
  • Visible rust streaks, bulging, or localized thinning on the shell surface
  • Audible popping or cracking sounds during temperature changes or fluid filling/draining
Engineering Tips
  • Implement regular ultrasonic thickness testing to monitor corrosion rates and schedule proactive repairs before failure
  • Install expansion joints or flexible connections to accommodate thermal movement and reduce stress concentrations
