Gas Distribution Manifold for Sparging Systems | Chemical Manufacturing Component

Product Specifications

Technical details and manufacturing context for Gas Distribution Manifold

Definition

The gas distribution manifold is a critical component of sparging systems that receives gas from a central supply line and evenly distributes it to multiple sparging points or diffusers. It ensures consistent gas flow and pressure to all connected outlets, enabling uniform gas dispersion in liquids for processes like aeration, carbonation, or chemical reaction enhancement. This manifold is designed for chemical manufacturing applications where precise gas distribution is required. It is available in materials such as Stainless Steel 316L, PTFE, and PVC, allowing selection based on chemical compatibility and process requirements. Key parameters include an operating pressure range of 1.0–1.6 MPa, a design temperature range of -10 to 80 °C, inlet connection sizes from DN25 to DN100 (ISO 7005), and outlet connection sizes from DN15 to DN50 (ISO 7005). The number of outlets can range from 2 to 8, with custom configurations available. The body material is typically SS316L (ASTM A182), and the seal material is PTFE (ASTM D4894). Surface roughness is ≤0.8 μm Ra (ISO 4287), and leakage rate is ≤0.01 mL/min at rated pressure (ISO 15848). Weight varies from 5 to 20 kg depending on size and configuration. The manifold operates by receiving gas through a single inlet and distributing it through multiple outlet ports. Internal baffles, valves, or flow restrictors may be used to balance pressure and flow rates across all outlets. It maintains system pressure while allowing individual control of gas flow to different sections of the sparging system. When selecting a manifold, verify that the operating pressure, temperature, connection sizes, and materials are compatible with your specific process conditions. Always confirm model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

Gas enters the manifold through a single inlet and is distributed through multiple outlet ports. Internal baffles, valves, or flow restrictors may be used to balance pressure and flow rates across all outlets. The manifold maintains system pressure while allowing individual control of gas flow to different sections of the sparging system.
