# Industrial Specification: Pressure Equalization Chamber

## 1. Technical Definition
A chamber within a steam distribution manifold designed to equalize pressure between different steam lines or zones.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-25 bar**. Failure boundary: **28 bar internal pressure at 150°C steam temperature**, Mechanism: **Yield strength exceedance of ASTM A106 Grade B carbon steel (241 MPa at 150°C) causing plastic deformation and rupture**.

### 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.

- **Caution**: 

### Q: What is the primary function of a pressure equalization chamber in steam systems?
**A**: The pressure equalization chamber balances pressure between different steam lines or zones within a distribution manifold, ensuring consistent steam flow and preventing pressure imbalances that could affect equipment performance or safety.

### Q: What materials are commonly used for manufacturing pressure equalization chambers?
**A**: These chambers are typically constructed from carbon steel for general industrial applications or stainless steel for corrosive environments or high-purity steam requirements, offering durability and resistance to high temperatures and pressures.

### Q: What are the key components included in a standard pressure equalization chamber BOM?
**A**: Standard components include the chamber body, drain port for condensate removal, inlet nozzle for steam entry, outlet nozzle(s) for distribution, and pressure gauge port for monitoring system pressure.
