Hemaokang Steel (Shandong) Co., Ltd. is proud to present our premium 304 Stainless Steel Pipe for Food Processing Equipment – a sanitary welded tubing solution designed to meet the highest hygiene standards in the food industry. With a proven export value of US$50 million to US$100 million annually and a dedicated team of 51-100 professionals, we deliver pipes that combine corrosion resistance, smooth interior surfaces, and precise dimensional tolerances. Our ISO 9001 certification ensures consistent quality across every batch, making us a trusted partner for food processors, breweries, dairy plants, and pharmaceutical manufacturers worldwide.

These pipes are manufactured from 304 stainless steel – a material known for its excellent formability, weldability, and resistance to organic acids and chlorides commonly found in food contact applications. The sanitary welded construction eliminates crevices and reduces bacterial growth, while the outer diameter range of 1.5" to 4" provides flexibility for various piping systems. Whether you need a standard 6m length or custom dimensions, our production line can accommodate your requirements.

Key Features & Technical Specifications

Superior Corrosion Resistance: 304 grade offers excellent protection against rust and pitting, even in wet or acidic environments.
Sanitary Welded Seam: Fully penetrated welds with smooth interior surfaces (no weld bead buildup) to prevent product entrapment and facilitate cleaning.
Wide Size Range: Available in nominal ODs from 1.5" to 4", with wall thickness options including Schedule 10, Schedule 40, and custom gauges.
Multiple Surface Finishes: Choose from 180 grit, 320 grit, or mirror polish (Ra ≤ 0.8 μm) to suit your specific hygiene or aesthetic requirements.
Strict Dimensional Tolerances: OD tolerance ±0.005" (0.13 mm) for precision fitting with standard tri-clamp or weld ferrules.
Long Lengths Available: Standard 5.8m or 6m, with custom lengths up to 12m upon request.
Certified Material Traceability: Each batch comes with mill test certificates (MTC) verifying chemical composition and mechanical properties.

Long Service Life: 304 stainless steel resists corrosion from food acids (e.g., citric, lactic) and cleaning chemicals, minimizing replacement costs.
Easy Installation: Precision‑rolled ODs allow for quick connection with standard tri‑clamp fittings, reducing labor time.
Customizable Options: We offer tailored wall thicknesses, lengths, and surface finishes to match your specific processing line requirements.
Cost‑Effective: Competitive pricing for high‑quality sanitary tubing, backed by bulk production capacity that supports both small and large orders.
