Center Pipe

The center pipe/inner screen is the central screening component in radial flow systems. Main used for flow collection or distribution inside vertical reactors. They are typically cylindrical, with the outer layer defining the boundary of the catalyst bed.

We implemented control procedures during the design and manufacturing phases to enhance process efficiency.

Center Pipes for Radial Flow Reactors: Optimizing Flow and Performance

Radial flow reactors are renowned for their efficiency in gas-solid catalytic and non-catalytic reactions, leveraging a unique design where gas flows perpendicularly to the reactor's axis. This configuration minimizes pressure drop by providing a large cross-sectional flow area, low flow velocity, and a short flow path. At the heart of these reactors lies the center pipe, a critical component for either collecting or distributing the flow within the catalyst bed.

What is a Center Pipe?

Center pipes, also known as inner screens, are precisely engineered cylindrical structures that define the inner boundary of the catalyst bed in radial flow systems. Installed within vertical reactors, these pipes act as the central hub for managing gas flow. They are often crafted with a slotted screen of triangular wire, forming an outer surface directly interacting with the catalyst layer. This specialized design serves a dual purpose: it retains the catalyst packing while simultaneously directing the flow towards the outlet, ensuring efficient reaction processing.

Flow Direction: Customization for Your Needs

We offer center pipes designed for both inward and outward flow configurations, with connecting nozzles positioned at either the upper or lower end to perfectly match your specific application requirements.

Center Pipes Reactor Internal

We recognize the importance of precision and reliability in radial flow reactors. That's why we implement strict control procedures throughout the design and manufacturing processes to ensure optimal performance and improve process efficiency. Additionally, we produce other critical components for radial flow reactors, including center pipes, scallops for reactor vessels.

Our Center Pipes Key Advantages:

Maximized Open Area: We achieve a high open area in our wedge wire screens through a meticulous combination of precise dimensional calculations, advanced manufacturing techniques, and stringent dimensional control during overall assembly. This ensures optimal flow distribution and minimizes hydraulic resistance.

Perfect Alignment: Maintaining perfect axial alignment is crucial for efficient operation. To achieve this, we utilize a laser controller to verify perpendicularity at every stage of production, ensuring consistent and reliable performance.

Dismountable Design: Our dismountable structure simplifies installation through the reactor hatch, saving you time and effort.

Minimized Clogging: The triangular wire design of the slit screen effectively prevents catalyst leakage and eliminates slot clogging, ensuring continuous operation.

Strict Tolerances: We maintain strict control over verticality and straightness tolerances, guaranteeing optimal performance and longevity.
