ASTM B163 UNS N02200 Seamless pipes for heat exchangers
ASTM B163 UNS N02200 Seamless pipes for heat exchangers
ASTM B163 UNS N02200 seamless tubing, also known as Pure Nickel 200, is specified for heat exchangers and condensers due to its excellent corrosion resistance, high-temperature strength, and mechanical properties. Key features include consistent chemical composition and mechanical properties (such as tensile and yield strength), a wide range of sizes, and extensive testing requirements to ensure performance. It is suitable for a wide range of applications involving reducing acids and generally high-temperature environments.
What is SB 163 tubing?
SB 163 specifies nickel and nickel alloy seamless tubing for use in condensers and heat exchangers. These tubing is constructed from various alloy grades, such as Alloy 400, Alloy 600, Alloy 800, and Nickel Alloy 200/201. These materials are selected for their ability to withstand high temperatures and severe corrosive environments.
ASTM B163 UNS N02200 is the specification for seamless nickel and nickel alloy condenser and heat exchanger tubing. UNS N02200 represents commercially pure nickel (99.6%) and is commonly used in a variety of industrial applications due to its excellent corrosion resistance and high thermal conductivity. ASTM B163 outlines the chemical composition, mechanical properties, dimensions, and tolerance requirements for UNS N02200 and other nickel alloy seamless tubing.

Gnee Steel specializes in the production of various nickel-based alloys. Gnee Steel's product packaging includes steel strapping: Pipes with an outer diameter of 3 inches or less are typically strapped together with polypropylene film to prevent rust during sea transportation, and then secured with steel strapping. Wooden boxes/crates: Pipes are typically packaged in wooden boxes or crates to protect them during transportation, especially those that are longer or have larger diameters. Seaworthy export packaging: Suppliers typically use standard seaworthy export packaging methods, which may include a variety of materials and techniques to protect the pipes during transportation. Tarpaulin packaging: This prevents rain, seawater, and other external factors from penetrating the export wooden crates during transportation. Gnee Steel specializes in the production and sale of alloy materials. Gnee Steel's products are widely used in aerospace, chemical, power, automotive, and nuclear energy industries, and we can provide customized alloy material solutions based on customer needs.
