# Industrial Specification: Head Body

## 1. Technical Definition
The main structural housing of a distribution head that contains and supports internal components.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-25 bar internal pressure, -40°C to 120°C ambient temperature**. Failure boundary: **35 bar internal pressure causing plastic deformation, 150°C causing material yield strength reduction below 200 MPa**, Mechanism: **Von Mises stress exceeding ASTM A36 steel yield strength of 250 MPa at 35 bar, thermal expansion coefficient mismatch (11.7 μm/m·°C steel vs 23.1 μm/m·°C aluminum internals) causing fatigue cracking**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Corrosion-induced wall thinning below 3 mm minimum thickness | 8 | Catastrophic housing rupture at 28 bar operating pressure | 316L stainless steel cladding with 1.5 mm minimum thickness, cathodic protection at -850 mV vs Cu/CuSO4 |
| Thermal cycling between -40°C and 120°C at 15 cycles/hour | 8 | Fatigue cracking at weld joints after 50,000 cycles | Post-weld heat treatment at 620°C for 2 hours, ultrasonic testing at 5 MHz frequency for crack detection &gt;0.5 mm |
