# Industrial Specification: Coupling Body

## 1. Technical Definition
The main structural housing of a utility coupler that contains and protects internal components while providing mounting interfaces.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-25 MPa (0-250 bar) internal pressure, -40°C to 150°C temperature**. Failure boundary: **Material yield strength threshold: 250 MPa for steel alloys, 150 MPa for aluminum alloys; Fatigue limit: 10^7 cycles at 100 MPa stress amplitude**, Mechanism: **High-cycle fatigue from cyclic pressure loading exceeding material endurance limit; Stress corrosion cracking in chloride environments above 60°C**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Misalignment exceeding 0.5° angular or 0.2 mm radial during installation | 8 | Premature bearing wear leading to shaft vibration exceeding 4.5 mm/s RMS | Laser alignment verification protocol with 0.1° angular tolerance |
| Corrosive fluid ingress with chloride concentration &gt; 50 ppm | 8 | Pitting corrosion initiating at sealing surfaces, progressing at 0.5 mm/year | Duplex stainless steel (UNS S31803) construction with 22% chromium minimum |
