UNS N02200/DIN W. NR. 2.4060, 2.4066 seamless pipe is a high-performance nickel alloy seamless pipe engineered for demanding industrial applications. Crafted from commercially pure wrought Nickel 200 alloy, this pipe boasts exceptional resistance to reducing chemicals and caustic alkalis, thanks to its ability to form a passive oxide film in oxidizing conditions. Designed to maintain product purity in critical processes, it is a trusted choice for industries where reliability and corrosion resistance are non-negotiable. With a service temperature limit of 315℃ (beyond which Nickel 201 is recommended to avoid graphitization), this seamless pipe also features a high Curie temperature, excellent magnetostrictive properties, and superior thermal and electrical conductivities compared to other nickel alloys. Whether for chemical storage, aerospace components, or food processing, it delivers consistent performance that meets global industry standards.

Production Processes |
We source high-quality raw materials from renowned Chinese mills such as Tingshan, Tisco, Bao Steel, Yongxing, and Walsn. Each batch undergoes rigorous MTC (Material Test Certificate) checking, PMI (Positive Material Identification), tensile strength testing, and surface/dimension inspection to ensure it meets our strict quality criteria.
Our state-of-the-art facility operates 18 seamless production lines and 3 perforation production lines, enabling annual output of 30,000 tons of austenitic steel and duplex steel pipes. A dedicated team oversees the entire production process, from billet heating and piercing to rolling, heat treatment, and finishing. Each step is documented via process flow cards, which are retained for quality traceability.
After forming, the UNS N02200 seamless pipe undergoes precision finishing, including cutting, deburring, and surface treatment. We also offer customized precision machining services to meet unique customer requirements, ensuring the pipe integrates seamlessly into specific systems.
Quality Control Of Huashang Duplex Steel Seamless Pipe |
Raw Material Quality Control: All incoming materials are inspected for chemical composition, mechanical properties, and surface defects before entering production.
In-Process Monitoring: Specially assigned personnel track production progress, verifying compliance with process parameters and conducting real-time checks to prevent defects.
Pre-Shipment Testing: Our dedicated quality inspection team performs comprehensive tests, including:
Routine appearance inspection
PMI testing to confirm material composition
Non-destructive testing (eddy current testing, ultrasonic testing)
Physical and chemical property tests (metallographic test, impact test, tensile test, hardness test)
Dimensional measurement using precision test blocks
Our factory holds ISO9001:2015 quality management system certification and is approved by leading classification societies such as BV, ABS, CCS, DNV/GL, TUV, LR, and KR. We also accept third-party inspections to provide customers with additional peace of mind.
Every DIN W. NR. 2.4060 seamless pipe is accompanied by complete documentation, including MTC, inspection reports, and certification records. This full traceability ensures accountability from raw material to finished product.

Packaging and Containerization |
Nickel 200 is ideal for service temperatures below 315℃, while Nickel 201 (a low-carbon variant) is recommended for higher temperatures to avoid graphitization, which can compromise mechanical properties. Both offer excellent corrosion resistance, but Nickel 201 is better suited for high-temperature applications.
Yes. UNS N02200/DIN W. NR. 2.4066 seamless pipe is highly resistant to reducing chemicals and caustic alkalis, making it perfect for corrosive environments such as chemical processing plants, oil & gas facilities, and wastewater treatment systems.
Absolutely. We offer customized outer diameter, wall thickness, length, and machining services to meet your specific needs. Contact our team to discuss your project requirements.
