Industry-Verified Manufacturing Data (2026)

Tank Body

Based on aggregated insights from multiple verified 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.

Product Specifications

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
Technical Parameters
  • Nominal capacity of the tank body (L) Standard Spec
Components / BOM
  • Mounting Brackets
    Secures the tank body to the vehicle or equipment frame
    Material: Steel or aluminum
  • Baffles (if applicable)
    Reduces fluid sloshing during vehicle movement
    Material: Same as tank body material
Engineering Reasoning
0-2.5 bar (gauge pressure)
3.8 bar internal pressure causing plastic deformation in 304L stainless steel
Design Rationale: Yield strength exceedance at 205 MPa for 304L stainless steel at 20°C, following von Mises yield criterion
Risk Mitigation (FMEA)
Trigger Electrochemical pitting corrosion from chloride contamination exceeding 25 ppm
Mode: Wall perforation leading to DEF leakage at 0.5 mm thickness reduction
Strategy: Cathodic protection system with -0.85 V vs. Ag/AgCl reference electrode
Trigger Thermal cycling between -11°C and 50°C exceeding 1000 cycles
Mode: Low-cycle fatigue cracking initiating at weld heat-affected zones
Strategy: Post-weld heat treatment at 1050°C for 30 minutes followed by rapid quenching

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
