Duplex Alloy Pipe
High Strength & Lightweight: Approximately double the yield strength of standard austenitic grades (e.g., 304/316), enabling lighter and more durable designs.
Superior Corrosion Resistance: Excellent resistance to chloride stress corrosion cracking, pitting, and crevice corrosion, particularly in marine and chemical media.
Grade Flexibility: Available in standard duplex (e.g., 2205/UNS S32205), super duplex (e.g., 2507/UNS S32750), and lean duplex grades to meet varying mechanical and environmental requirements.
Comprehensive Compliance: Manufactured to ASTM, ASME, EN, and other international standards, offered in seamless and welded forms.
Ideal for offshore and marine structures, chemical processing plants, oil and gas pipelines, desalination systems, and heat exchangers. We provide customized cutting, bending, welding support, and full traceable certification to meet your project's technical and quality demands.
A comprehensive matrix of high-performance alloy pipe products is available, covering five core alloy series: Inconel, Monel, Hastelloy, Nickel, and Duplex, designed to address the full spectrum of extreme operating condition requirements. From high-temperature oxidation resistance above 1100°C to strong acid, strong alkali, and seawater corrosion environments, from high-stress pressure components to special electromagnetic property applications, these alloy pipes provide tailored material solutions for critical systems. All products strictly comply with international standards such as ASTM/ASME, NACE, EN, and ISO, and are supplied with complete material certification and full traceability documentation, meeting stringent certification requirements of high-end sectors including petrochemicals, marine engineering, aerospace, and new energy.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
