Structured Manufacturing Data (2026)

Tank Body

Based on aggregated insights from structured factory profiles within the CNFX directory, the standard Tank Body used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Tank Body is characterized by the integration of Mounting Brackets and Baffles (if applicable). In industrial production environments, manufacturers listed on CNFX commonly emphasize High-density polyethylene (HDPE) construction to support stable, high-cycle operation across diverse manufacturing scenarios.

The main structural container of a DEF tank that holds the diesel exhaust fluid.

Technical details and manufacturing context for Tank Body

Definition
The Tank Body is the primary containment vessel within the DEF Tank with Level Sensor system, designed to safely store diesel exhaust fluid (DEF) while maintaining its chemical properties. It serves as the foundation for mounting other components like the level sensor, fill neck, and outlet fittings.
Working Principle
The Tank Body provides a sealed, chemically resistant environment for DEF storage. It withstands internal pressure from fluid weight and potential thermal expansion while preventing contamination and evaporation. Its geometry is optimized for complete fluid drainage and integration with level sensing equipment.
Common Materials
High-density polyethylene (HDPE), Stainless steel

Application Fit & Sizing Matrix

Operational Limits
pressure: Atmospheric to 0.5 bar gauge
flow rate: N/A (static storage)
temperature: -40°C to +50°C
slurry concentration: Not applicable - DEF is a clear aqueous solution
Media Compatibility
✓ Diesel Exhaust Fluid (32.5% urea solution) ✓ Deionized water ✓ Aqueous urea solutions (20-40% concentration)
Unsuitable: Hydrocarbon fuels (diesel, gasoline) or oxidizing chemicals
Sizing Data Required
  • Required DEF storage volume (liters)
  • Vehicle fleet size and consumption rate
  • Refill frequency and logistics constraints

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Corrosion
Cause: Chemical attack from stored contents or atmospheric exposure, leading to material degradation and loss of structural integrity.
Fatigue cracking
Cause: Cyclic stresses from thermal expansion/contraction, pressure fluctuations, or mechanical vibrations, resulting in crack initiation and propagation.
Maintenance Indicators
  • Visible leaks, weeping, or discoloration on the tank surface
  • Audible popping, cracking, or hissing sounds indicating stress or pressure issues
Engineering Tips
  • Implement regular non-destructive testing (e.g., ultrasonic thickness gauging) to monitor wall thickness and detect early corrosion
  • Install proper cathodic protection systems and apply corrosion-resistant coatings appropriate for the stored medium

Compliance & Manufacturing Standards

Reference Standards
ISO 11439:2013 - Gas cylinders - High pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles ASME Boiler and Pressure Vessel Code (BPVC) Section VIII - Rules for Construction of Pressure Vessels EN 13445:2021 - Unfired pressure vessels
Manufacturing Precision
  • Wall Thickness: +/-5% of nominal thickness
  • Circularity (Roundness): 0.5% of nominal diameter
Quality Inspection
  • Hydrostatic Pressure Test
  • Ultrasonic Thickness Testing

Frequently Asked Questions

What materials are used for DEF tank bodies?

DEF tank bodies are typically constructed from high-density polyethylene (HDPE) for corrosion resistance or stainless steel for enhanced durability in demanding industrial applications.

Why do some DEF tank bodies include baffles?

Baffles are internal partitions that prevent fluid sloshing during transport, maintaining stability and reducing stress on the tank structure and mounting system.

How are DEF tank bodies mounted on machinery?

DEF tank bodies feature integrated mounting brackets designed for secure installation on various machinery frames, ensuring stability during operation and transport.
