Processing dairy and food powders demands strict hygiene standards. In systems where sanitary design principles are enforced, equipment must undergo rigorous Clean-in-Place (CIP) washdowns. However, standard flexible sleeves often become vulnerable points in these sanitary lines—degrading rapidly under hot water or harboring microbiological growth in hidden mechanical crevices.

To overcome the challenges of high-frequency washdowns, the SOSHH engineering team developed the CIP Sanitary Flexible Connector. Engineered from 100% pure hydrolysis-resistant polyether TPU, this connector provides a high-integrity hygienic seal for food, beverage, and dairy grade powder processing.

The Material Science Perspective: Ether vs. Ester TPU

When sourcing sanitary flexible connectors, many plant managers encounter sleeves made from Ester-based TPU. While Ester-TPU is common, it is susceptible to hydrolysis—a chemical breakdown that occurs when the polymer is exposed to hot water and steam over extended periods.

SOSHH addresses this by utilizing 100% Pure Ether-Based TPU. Polyether TPU is widely recognized in polymer science for its high hydrolysis resistance. Because this material is based on an open-domain chemical formulation and unrestricted by proprietary licensing concepts, our CIP sleeves withstand aggressive, high-temperature caustic washdowns without premature degradation, maintaining physical integrity across high-frequency cleaning cycles.

Zero-Crevice Design: Eliminating Mechanical Dead Zones

In dairy and food processing, internal ledges, clamps, or crevices represent potential accumulation points for residues. Traditional connections relying on internal mechanical clamping elements can create flow obstructions that complicate thorough cleaning.

The SOSHH CIP Connector features an advanced HF-Welded Exterior Pocket Architecture. By utilizing High-Frequency (HF) welding to seal the retention elements strictly on the exterior of the sleeve, the internal flow path remains flush and uniform. This creates a Zero-Crevice Smooth Inner Bore. During a CIP cycle, cleaning solutions flow smoothly down the uninterrupted internal walls, facilitating complete drainability and cleanliness.

Regulatory Compliance & Documentation

Product safety in food and dairy processing requires robust documentation. The SOSHH CIP Sanitary Flexible Connectors are engineered and supported by comprehensive compliance data:
