SUS304 Stainless Steel Flange Sleeve: Precision-Machined for Hygienic & Industrial Applications

This precision flange sleeve is manufactured from SUS304 stainless steel, designed to deliver reliable, leak-proof connections in fluid pipelines, food and pharmaceutical equipment, and industrial automation systems. Its flanged design ensures secure installation, while the precision-machined inner bore guarantees consistent fit and alignment.

Manufacturing & Quality

Process: Produced via CNC turning composite machining, ensuring dimensional accuracy, concentricity, and smooth surface finish.

Tolerance: Dimensional accuracy controlled within ±0.02mm, complying with GB/T 1804-m standards for reliable fit and leak-free performance.

Core Equipment: High-precision CNC lathes and machining centers, paired with rigorous in-process inspection.

Surface & Performance

The sleeve undergoes polishing, passivation, and ultrasonic cleaning post-treatments, eliminating contaminants and enhancing corrosion resistance. The smooth, scratch-free surface meets the requirements of hygienic environments (food/pharmaceutical) and continuous-operation industrial settings.

Customization & Lead Time

Customization: Available in custom inner/outer diameters, lengths, flange configurations, and material grades (e.g., SUS316) to match your unique system requirements.

Lead Time: 7-10 days for samples; 15-20 days for bulk orders.

Applications

Ideal for fluid transfer systems, food processing equipment, pharmaceutical machinery, and industrial automation lines, providing durable, corrosion-resistant connections for demanding environments.
