Embedded G Type Finned Tube， ASTM B163 UNS N04400 Nickel Alloy Tube with Aluminum Fins
The base tube material is Monel400. Then the fin strip is wound into a machined groove and securely locked into place by back filling with base tube， which ensuring that maximum heat transfer is maintained at high tube metal temperatures. Monel400 is a corrosion-resistant alloy. This alloy has excellent corrosion resistance. It generally doesn’t produce stress corrosion cracks and has good cutting performance. After finning services， the alloy tube with GType fins can have better heat transfer efficiency than normal straight base tube.
ASTM B163 UNS N04400 is a specification for nickel-iron-chromium alloy tubes， commonly known as Monel 400. Embedded G type finned tubes are tubes with fins that are attached to the outer surface of the tube in a G-shaped pattern. These finned tubes are used in various heat transfer applications where increased surface area is needed for enhanced heat transfer efficiency. The G type fins provide a larger surface area compared to plain tubes， allowing for better heat transfer between the fluid inside the tube and the surrounding environment. The use of Monel 400 alloy in these finned tubes provides excellent corrosion resistance and high strength， making them suitable for use in harsh environments. The ASTM B163 specification ensures that the tubes meet certain quality and dimensional standards to ensure their performance and longevity in service. ASTM B163 UNS N04400 embedded G type finned tubes are a reliable and efficient choice for heat transfer applications in industries such as chemical processing， petroleum refining， and power generation.
