Duplex Stainless Steel Pipe

Duplex Stainless Steel Pipe is a special type of stainless steel pipe with a dual-phase microstructure combining austenitic and ferritic components. It integrates the corrosion resistance and toughness of austenitic stainless steel with the high strength and resistance to chloride stress corrosion of ferritic stainless steel, making it a high-end pipe material for harsh environments such as marine engineering and chemical industries.

 Marine Engineering: Duplex Stainless Steel Pipe is used in reverse osmosis membrane housings in desalination plants, seawater transmission pipelines, cooling water pipes for offshore wind turbine towers, and risers for subsea oil and gas transmission. It can withstand the corrosion of high-salinity seawater and marine salt spray.

 Petrochemical Industry: Suitable for acidic oil and gas well casings, oil and gas transmission pipelines, as well as pipelines for transporting chemical media such as chloride-containing brine and dilute sulfuric acid, and desulfurization and denitrification systems, resisting acidic corrosion such as H₂S and CO₂.

 Environmental protection and water treatment: Used as pipelines for transporting high-salt wastewater and landfill leachate, as well as for sludge dewatering and chemical dosing in municipal wastewater treatment plants, addressing complex corrosive environments with high chloride ions.

 Special equipment: Used in bleaching processes of pulp and paper industries for chlorine-containing bleaching agents, and as heat exchange tubes in pressure vessels and heat exchangers in the chemical and nuclear power industries, balancing high strength, corrosion resistance, and heat exchange requirements.

Henan Tieyao Trading Co., Ltd. has established a complete production chain from smelting and processing to packaging and transportation. For stainless steel products, strict end-to-end quality control, from raw material selection to finished product testing, follows standardized procedures and supports third-party testing to ensure the reliability of exported products. Its well-established global logistics network ensures efficient delivery of products to overseas destinations.
