Component Specifications

Definition
The Mixer Housing/Pipe Section is a precision-engineered cylindrical or rectangular enclosure that forms the main body of a static mixer. It houses stationary mixing elements (helical, Kenics, or other geometries) and provides controlled flow channels for fluids. This component maintains structural integrity under process pressures while ensuring proper alignment of mixing elements for consistent radial and axial mixing performance. It serves as both a containment vessel and flow director in continuous inline mixing applications.
Working Principle
Fluid enters the housing under pressure and flows through sequentially arranged stationary mixing elements. The housing's internal geometry creates controlled turbulence and laminar shear by dividing and recombining fluid streams. Each pipe section maintains consistent cross-sectional area to preserve velocity profiles while the housing material minimizes energy loss through smooth internal surfaces. The component operates without moving parts, relying on the fixed geometry to achieve mixing through flow division and recombination.
Materials
Stainless steel (AISI 304/316L), carbon steel (ASTM A106), duplex steels (2205), nickel alloys (Hastelloy C-276), titanium (Grade 2), or engineered polymers (PTFE-lined, PP, PVDF) depending on chemical compatibility and pressure requirements. Surface finishes: Ra ≤ 0.8 μm for sanitary applications, electropolished for CIP/SIP compatibility.

Frequently Asked Questions

What is the difference between standard and sanitary mixer housings?

Sanitary housings have electropolished interiors (Ra ≤ 0.4 μm), crevice-free designs, and Tri-Clamp connections for cleanability, while standard housings use rougher finishes and flanged connections for general industrial use.

How do I select the appropriate housing material?

Consider fluid chemistry (pH, chlorides), temperature, pressure, and cleaning requirements. Stainless steel 316L is standard for corrosive fluids, while lined housings are used for highly aggressive chemicals.

Can mixer housings be customized for specific applications?

Yes, custom lengths, diameters, connection types, and material grades are available. Special coatings (PTFE, PFA) can be applied for chemical resistance.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
