# Industrial Specification: Heated Delivery Lines

## 1. Technical Definition
Temperature-controlled fluid transport lines within the DEF/AdBlue injection system

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.5-4.5 bar at 30-50°C**. Failure boundary: **Pressure drop below 1.8 bar or temperature exceeding 65°C**, Mechanism: **Urea crystallization due to insufficient pressure preventing complete atomization, combined with thermal degradation of urea solution above 65°C forming biuret and cyanuric acid deposits**.

### 2.1 Analytical Physics Model
Governed by the **Heat Sterilization F0 Lethality Model**:

> **Primary Equation**: $F_0 = \int_{0}^{t} 10^{(T-121.1)/z} dt$  
> **Engineering Impact**: Validates microbial reduction integrity for aseptic packaging.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| T | Process Temp (°C) | **$T \in [30-50°C]$ °C** (Per `temperature_range`) |
| t | Exposure Time (min) | Engineering Constant |
| z | Z-value | **10 °C** (Standard for *C. botulinum*) |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Insufficient trace heating power density below 15 W/m | 8 | Urea crystallization forming 0.5-2.0 mm thick deposits along inner walls | Redundant heating circuits with independent PID controllers maintaining 40±2°C |
| Corrosion-induced pitting reaching 30% wall thickness reduction | 8 | Stress corrosion cracking propagating at 0.1-0.3 mm/1000h in 316L stainless steel | Duplex stainless steel (UNS S32205) with 0.02% max carbon content and cathodic protection at -850 mV vs Ag/AgCl |
