# Industrial Specification: Fluid Cap / Body

## 1. Technical Definition
The main housing component of a spray nozzle assembly that contains and directs fluid flow.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15 bar (7.25-217.5 psi)**. Failure boundary: **18.5 bar (268.3 psi) internal pressure causing yield stress of 250 MPa in 316L stainless steel**, Mechanism: **Plastic deformation due to hoop stress exceeding material yield strength: σ_h = (P·D)/(2·t) where P=18.5 bar, D=25 mm, t=1.5 mm**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

| Symbol | Variable Definition | Localized Reference |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are available for the fluid cap/body?
**A**: The fluid cap/body is available in Stainless Steel 316 for corrosion resistance, Brass for durability and cost-effectiveness, and PVC for chemical compatibility and lightweight applications.

### Q: What are the key components in the fluid cap/body BOM?
**A**: The bill of materials includes an Inlet Thread for fluid connection, an Internal Chamber for flow direction, a Mounting Flange for secure installation, and an Orifice Seat for precise fluid control.

### Q: How does the fluid cap/body function in spray nozzle assemblies?
**A**: It serves as the main housing that contains and directs fluid flow from the inlet through the internal chamber to the orifice, ensuring controlled spray patterns in machinery and equipment manufacturing.

## 6. Manufacturing Compliance
- ISO 1179-1:2013 (CONNECTIONS FOR GENERAL USE AND FLUID POWER - PORTS AND STUD ENDS)
- ANSI/ASME B16.5:2020 (PIPE FLANGES AND FLANGED FITTINGS)
- DIN 2353:2017 (TUBE FITTINGS WITH CUTTING RING FOR GENERAL AND HYDRAULIC USE)
