316L Stainless Steel Pipes (3/4" OD) are ultra-clean, corrosion-resistant tubing designed for critical applications in pharmaceutical manufacturing, biotechnology, and brewery systems. Compliant with ASME SA789, these pipes feature ultra-low carbon content (≤0.03%) and 2–3% molybdenum (Mo) to resist pitting and crevice corrosion in aggressive environments, including chloride-rich or acidic media. The 3/4" outer diameter (OD) with precision-controlled wall thickness ensures compatibility with high-purity fluid transfer systems requiring strict hygiene and minimal contamination risks. Electropolished interiors (Ra ≤0.5µm) and passivated surfaces enhance cleanability, making them ideal for sterile processes, CIP/SIP systems, and FDA-regulated operations.JIANGSU CHINA STEEL UNION INDUSTRIAL CO.,LTD
