Main Application Areas of AL6XN Pipes
al6xn tubing in Chemical and Petrochemical Industries
Organic Acid Production: Such as feed pipes and finished product conveying pipes in reactors for acetic acid, propionic acid, and adipic acid production.
Inorganic Acid Treatment: Such as pickling solution conveying pipes in sulfuric acid titanium dioxide production and phosphoric acid conveying pipes in phosphate fertilizer production, replacing traditional fiberglass or graphite pipes.
Petrochemical Refining: Such as sulfur-containing wastewater pipelines in crude oil desulfurization units and high-temperature oil and gas pipelines in catalytic cracking units.
al6xn pipe in Oil and Gas Industry
Offshore Oil and Gas Extraction: Such as wellhead production pipes for offshore platforms and subsea oil pipelines (shallow sea areas), resistant to corrosion from seawater and sulfur-containing compounds (such as H2S) in crude oil, replacing expensive nickel-based alloy pipes.
Shale Gas Extraction: Such as fracturing fluid (containing high concentrations of chloride salts) conveying pipes and wellhead gathering pipelines.
LNG Processing: Such as cryogenic pipelines (temperatures as low as -162℃) in LNG liquefaction units, utilizing their low-temperature high toughness characteristics to prevent brittle fracture of pipelines at low temperatures.
welding al6xn pipe in Pharmaceutical and Food Processing Industries
Pharmaceutical Industry: Examples include fermenter connection pipes in antibiotic production and purified water delivery pipes in injectable drug production, requiring resistance to corrosion from organic acids and alkaline washing solutions.
Food Processing: Examples include finished product delivery pipes in the production of food additives such as citric acid and lactic acid, requiring resistance to organic acid corrosion and ensuring no heavy metal leaching (meeting FDA food contact material standards).
al6xn / n08367 in Seawater Treatment and Marine Engineering
Seawater Desalination: Examples include high-pressure seawater delivery pipes and desalinated water output pipes in reverse osmosis seawater desalination plants, requiring resistance to pitting and crevice corrosion from seawater.
Marine Engineering: Examples include cooling water pipes for offshore wind power platforms and ballast water pipelines for ships, requiring resistance to seawater erosion and salt spray corrosion from the marine atmosphere.
al6xn n08367 in Nuclear Power Industry
Radioactive Wastewater Treatment Systems: Used to transport radioactive wastewater containing boric acid and lithium, preventing radioactive contamination caused by pipeline corrosion and leakage.
Nuclear Island Cooling Systems: Serving as secondary-side cooling water pipes, transporting cooling water containing corrosion inhibitors.
al6xn alloy steel in Environmental Protection Industry
Waste Incineration Power Generation Flue Gas Treatment: Absorption Towers Used in Flue Gas Desulfurization and Denitrification Devices.
