Primarily composed of nickel (over 60%), molybdenum (26-30%), and small amounts of iron and carbon, this alloy is engineered to resist severe reduction conditions, particularly in environments containing hot hydrochloric acid. The seamless construction ensures uniform wall thickness and structural integrity, eliminating weak points that could arise from welding seams. This makes it a preferred choice for industries where material degradation due to chemical exposure is a critical concern.
Exceptional Corrosion Resistance: UNS N10001 demonstrates outstanding resistance to reducing acids, including hydrochloric, sulfuric, and phosphoric acids at elevated temperatures. It outperforms many stainless steels and other nickel alloys in environments where oxidizing agents are absent, making it ideal for processing units handling concentrated acids.
High Thermal Stability: The alloy maintains its mechanical properties across a wide temperature range, from sub-zero conditions to over 1000°C. This stability ensures consistent performance in both cryogenic storage and high-temperature reaction vessels.
Superior Mechanical Strength: Despite its high nickel content, the seamless pipe offers excellent tensile and yield strength, combined with good ductility. This balance of properties allows for easy forming, machining, and welding, while resisting stress-induced failures in high-pressure systems.
Purity and Uniformity: The seamless manufacturing process eliminates weld-related imperfections, providing a homogenous microstructure that enhances resistance to pitting and crevice corrosion. The inner surface can be precision-finished to minimize fluid turbulence and material buildup.
UNS N10001 Seamless Pipes are widely used in chemical processing industries, particularly in the production of fertilizers, synthetic fibers, and pharmaceutical intermediates. They are essential for transporting and containing hot, concentrated hydrochloric acid in pickling tanks, reactor columns, and heat exchangers. In the petroleum sector, these pipes are utilized in downstream processes where acidic byproducts are present, such as in alkylation units and sulfur recovery plants. Additionally, they find use in the pulp and paper industry for handling corrosive black liquor and bleaching agents. Their reliability in extreme environments also makes them suitable for marine applications near industrial coastlines, where saltwater and chemical emissions create highly corrosive conditions.
Our pipe factory has 296 employees ,including 4 senior engineers,18 engineers and 38 professional technicians.
We can produces 30,000tons of austenitic steel and duplex steel pipes annually with 18 seamless production lines and 3 perforation production lines.
Our pipe factory has been certified to the ISO9001:2015 quality management system and certified by various classification societies (such as BV, ABS,CCS,DNV/GL,TUV,LR,KR etc).
