# Industrial Specification: Well Body

## 1. Technical Definition
The main structural component of a thermocouple well that houses and protects the temperature sensor.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-600°C, 0-100 bar**. Failure boundary: **Material yield strength at 650°C (e.g., 316SS: 145 MPa), thermal stress exceeding 80% of ultimate tensile strength**, Mechanism: **Thermal fatigue from cyclic temperature gradients exceeding 200°C/min, creep deformation above 0.4Tm (melting temperature)**.

### 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 |
