# Industrial Specification: Port Body / Fitting

## 1. Technical Definition
The main structural component of a pressure test port that provides the connection interface and housing for internal elements.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-600 bar at 20°C, 0-400 bar at 150°C**. Failure boundary: **Yield strength exceeded at 650 MPa von Mises stress (material-dependent), burst pressure at 900 bar**, Mechanism: **Plastic deformation from hoop stress exceeding yield strength (σ_θ = P·r/t), following Tresca yield criterion**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
