The Acid-Resistant Stainless Steel Tubing is specifically engineered to withstand highly aggressive acidic environments, including sulfuric, hydrochloric, nitric, phosphoric, and organic acids. Manufactured from high-performance austenitic and duplex stainless steel grades with elevated chromium, nickel, and molybdenum content, this tubing provides exceptional resistance to general corrosion, pitting, and intergranular attack. Its seamless construction ensures uniform wall thickness and eliminates weld-related vulnerabilities, making it the reliable choice for acid handling systems in chemical processing, mining, and industrial applications.

PREN = Pitting Resistance Equivalent Number (Cr% + 3.3×Mo% + 16×N%). Higher PREN indicates better acid corrosion resistance.

Tested in accordance with ASTM E8 / E8M.

Always verify compatibility based on specific temperature and concentration.

• Superior Acid Corrosion Resistance – Formulated to withstand aggressive acidic media

• High Molybdenum Content – Critical for reducing acid attack in reducing environments

• Copper Addition (904L / Alloy 20) – Enhances resistance to sulfuric acid

• High Nickel Content – Provides excellent resistance to chloride-induced stress corrosion cracking

• Passivated Surface – Optimized oxide layer for maximum acid protection

• Seamless Construction – No weld seams to initiate corrosion

• Wide Temperature Range – Maintains integrity from cryogenic to elevated temperatures

• Sulfuric Acid Plants – Acid transfer lines, heat exchangers, storage tank piping

• Phosphoric Acid Production – Reactor feed lines, evaporator tubes

• Nitric Acid Service – Concentrator columns, absorption tower piping

• Hydrochloric Acid Handling – Dilute acid transfer and storage (Alloy 20 / 904L)

• Pickling Lines – Steel mill acid recovery systems

• Chemical Tankers – Cargo piping for bulk liquid acids

• Mining & Metallurgy – Leaching circuits, acid drainage systems

• Pharmaceutical Synthesis – Organic acid process lines

• Food Processing – Citric and lactic acid handling
