Food-Grade Porous Stainless Steel Tube for Nitrogen Flushing

Precision-engineered sintered SS tubes for hygienic gas displacement in food, beverage & pharmaceutical processes

Our food-grade porous stainless steel tubes are designed for nitrogen flushing applications where hygienic, uniform, and efficient gas dispersion is essential. Manufactured using high-purity 316L stainless steel, these sintered tubes are ideal for oxygen displacement, shelf-life extension, and contamination prevention in sensitive processing environments such as food packaging, dairy, brewing, edible oils, and pharmaceuticals.

Through isostatic pressing and high-temperature sintering, these porous metal tubes offer a rigid structure with controlled pore size distribution, ensuring long-term performance and reusability under demanding conditions.

Key Features & Benefits

✅ Uniform Nitrogen Diffusion

The sintered porous structure delivers even and controlled nitrogen flow, ensuring complete and efficient oxygen purging during flushing or sparging operations. This helps minimize gas waste while maximizing flushing performance.

✅ 100% Food-Safe Construction

Made from 316L stainless steel, certified to FDA CFR 21 177.2600 and USP Class VI, the filter tubes are fully compliant with global food safety standards for contact with food, beverages, or pharmaceuticals.

✅ Corrosion & Temperature Resistance

Built to handle temperatures up to 600°C (1112°F) and operating pressures up to 3.0 MPa, these porous tubes provide excellent performance in both CIP (Clean-in-Place) and SIP (Steam-in-Place) systems.

✅ Long Service Life & Reusability

The durable sintered metal structure allows repeated use after high-temperature sterilization or chemical cleaning. This results in lower maintenance costs and total cost of ownership.

✅ Consistent Pore Structure

Advanced sintering technology ensures tight pore size tolerance, high porosity, and mechanical strength, enabling high-efficiency nitrogen flushing with precise control over flow dynamics.
