Distribution Manifold/Ducts for Nitrogen Atmosphere Systems

Product Specifications

Technical details and manufacturing context for Distribution Manifold/Ducts

Definition

The Distribution Manifold/Ducts are a critical component of the Nitrogen Atmosphere System, consisting of interconnected manifolds and ducts that transport and distribute inert nitrogen gas from the source to various points of use. This network maintains controlled atmospheric conditions by preventing oxidation and contamination in industrial processes. The system is designed to receive nitrogen gas from the supply source and distribute it through a branching network to multiple outlets or workstations, using pressure differentials and controlled flow rates to ensure even distribution while maintaining system pressure integrity.

Typical materials include Stainless Steel 316L and Aluminum Alloy. Key parameters to verify with the manufacturer include nominal diameter (DN15–DN100 per ISO 6708), design temperature (-40–85°C per ISO 15547), flow rate (0.5–5.0 m³/min per ISO 5167), pressure drop (≤0.05 MPa per ISO 5167), leakage rate (≤0.1 mL/min per ISO 15848), surface roughness (Ra 0.8–1.6 µm per ISO 1302), material grade (304/316L per ASTM A312), wall thickness (1.5–3.0 mm per ASME B36.10), weight (2–15 kg), connection type (flanged/threaded per ASME B16.5), and pressure rating (PN16 per ISO 7268). These values are reference ranges and must be confirmed for the specific model and application.

When selecting or verifying this component, consider the required flow capacity, operating pressure, temperature range, and connection compatibility. Interface with upstream nitrogen supply and downstream equipment must be checked. Maintenance signals include increased pressure drop, leakage, or surface degradation. Failure boundaries include exceeding pressure or temperature limits, which can cause material failure or seal leakage. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The distribution manifold/ducts receive nitrogen gas from the supply source and distribute it through a branching network of manifolds and ducts to multiple outlets or workstations. Pressure differentials and controlled flow rates ensure even distribution while maintaining system pressure integrity. The network is designed to minimize pressure drop and leakage, with smooth internal surfaces to reduce particle entrapment. Proper sizing and material selection are critical to maintain performance within specified limits.
