Compliant with ASTM B 622 standards, the Alloy B UNS N10001 Seamless Pipe is a specialized nickel-molybdenum alloy product designed for extreme reducing environments where conventional materials fail prematurely. This alloy, with its high nickel content (65% min) and 28% molybdenum, forms a protective passive film that resists dissolution in strong mineral acids, making it a benchmark material for corrosive chemical handling.
ASTM-Compliant Performance: Manufactured to strict ASTM B 622 specifications, this pipe ensures consistent chemical composition, mechanical properties, and dimensional accuracy. It undergoes rigorous testing for intergranular corrosion resistance and impact toughness to meet global industrial requirements.
Unmatched Acid Resistance: Alloy B excels in concentrated hydrochloric acid at temperatures up to 120°C and shows excellent resistance to sulfuric acid below 70% concentration. It is virtually immune to attack in phosphoric acid and formic acid, outperforming stainless steels and other nickel-based alloys in these media.
High-Purity Construction: The seamless manufacturing process eliminates impurities and weld discontinuities, ensuring a clean microstructure that prevents preferential corrosion paths. This purity is critical in applications where contamination from material degradation is unacceptable, such as in pharmaceutical and food processing.
Robust Mechanical Properties: Despite its focus on corrosion resistance, the pipe offers commendable tensile strength (700 MPa min) and elongation (40% min), allowing for installation in high-pressure systems and complex geometries without risk of mechanical failure.
ASTM B 622 Alloy B pipes are primarily used in chemical process industries where aggressive reducing acids are prevalent. They serve as the backbone of hydrochloric acid distillation units, pickling baths in steel plants, and reactors producing organic chemicals. In the mining sector, these pipes handle leachate solutions containing high levels of chloride and sulfuric acid, ensuring long service life in mineral processing equipment. Additionally, they are vital in the production of synthetic rubber and dyes, where contact with strong acids is unavoidable. Their compliance with international standards also makes them a preferred choice for export-oriented projects requiring ASTM-certified materials.
