Helical Solid Fin Tubes ASTM A213 TP347H Stainless Steel Tubes With 5052 Aluminum Fins
Helical solid fin tubes, also known as high frequency welding fin tubes, are specialized tubes that are manufactured using a high frequency welding process. This technique involves using high-frequency electrical currents to heat the edges of the metal, allowing them to be fused together without the need for additional filler materials.
This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T5, TP304, etc. Grades containing the letter H in their designation have requirements different from those of similar grades not containing the letter H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements.
Manufacture and Condition: Tubes shall be made by the seamless process and shall be either hot finished or cold finished, as specified. Grade TP347HFG shall be cold finished.
Heat treatment: cold worked: 2000°F [1100°C]; hot rolled: 1925°F [1050°C]

AL5052 is an aluminium-magnesium alloy, primarily alloyed with magnesium and chromium. 5052 is not a heat treatable aluminum alloy, but can be hardened through cold working.
The exceptional corrosion resistance of 5052 alloy against seawater and salt spray makes it a primary candidate for the failure-sensitive large marine structures, like tanks of liquefied natural gas tankers.
Generally applicable to power stations or large high-temperature equipment in the oil industry:
