Nickel Alloy Welded Pipes and Tubes
Nickel alloy welded pipes and tubes are produced from quality nickel alloy plates, strips, or coils and are welded using suitable processes. They are widely used in applications where large diameters, cost efficiency, and consistent dimensional accuracy are required.
Nickel Alloy Welded Tubes are suitable for heat exchangers, condensers, marine piping, chemical handling lines, and industrial equipment where corrosion resistance is important. Welded pipes are often preferred for larger sizes because they offer better availability and practical pricing compared to seamless pipes in certain dimensions.
We supply nickel alloy welded pipes and tubes in different lengths, wall thicknesses, schedules, and finishes. Each order can be supplied with required inspection documents, material test certificates, heat number traceability, and third-party inspection support when needed.
ASTM B161 Nickel Alloy Pipes
ASTM B161 is commonly searched by buyers as ASTM B161 Nickel Alloy Pipes. Technically, ASTM B161 covers Nickel UNS N02200 and low-carbon Nickel UNS N02201 in cold-worked seamless pipe and tube form. These are also widely known as Nickel 200 and Nickel 201 pipes and tubes.
ASTM B161 pipes are used where high nickel content, good mechanical properties, and resistance to corrosive media are required. Nickel 200 is commercially pure wrought nickel, while Nickel 201 has lower carbon content and is preferred in higher-temperature applications where graphitization needs to be minimized.
We can supply ASTM B161 seamless pipes and tubes with proper test certificates and documentation to support industrial, export, and project-based requirements.

Key Features of Nickel Alloy Pipes
Nickel alloy pipes are chosen because they offer a combination of corrosion resistance, strength, and stability in harsh service environments. They can perform in conditions where carbon steel or standard stainless steel may not be suitable.
Key advantages include:
- Excellent resistance to corrosion in selected chemical environments
- Good strength and toughness
- Suitable for high-temperature and pressure applications
- Better service life in demanding industrial systems
- Available in seamless and welded forms
- Suitable for heat exchanger, condenser, process piping, and marine applications
- Can be supplied with testing and documentation support
Applications of Nickel Alloy Seamless and Welded Pipes
Nickel Alloy Seamless Pipes and Nickel Alloy Welded Tubes are used in industries where reliability is critical. Common applications include:
- Chemical processing plants
- Petrochemical and refinery systems
- Marine and offshore piping
- Heat exchangers and condensers
- Power generation plants
- Oil & gas processing
- Desalination plants
- Caustic soda handling
- High-temperature process lines
- Industrial fabrication and equipment manufacturing
Choosing the right grade is important because each nickel alloy behaves differently in different environments. Temperature, chemical concentration, pressure, flow condition, and fabrication method should be reviewed before final material selection.
