Helical solid fin tubes, also known as high frequency welding fin tubes, are manufactured using a specialized process that utilizes high-frequency electrical currents to fuse metal edges without additional filler materials.
ASTM A213 TP347H S34709 base tubes are seamless ferritic and austenitic steel tubes designed for boiler, superheater, and heat-exchanger applications. Grades containing "H" provide enhanced creep-rupture strength.

AL5052 is an aluminum-magnesium alloy with exceptional corrosion resistance against seawater and salt spray, making it ideal for marine applications such as liquefied natural gas tankers. While not heat treatable, it can be hardened through cold working.
Ideal for power stations and high-temperature equipment in the oil industry, including:
