Cracking furnace tubes

U-tubes

In the steam cracking furnaces of the petrochemical industry, cracking furnace tubes and bend castings are required to withstand external temperatures approaching 1100°C, while simultaneously resisting internal carburization corrosion caused by hydrocarbon gases and external high-temperature oxidation. Consequently, the materials used must demonstrate exceptional corrosion resistance and creep resistance under these extreme high-temperature operating conditions.

Yantai Refra Heat Resistant Alloys Co., Ltd, relying on years of accumulated production experience and advanced manufacturing techniques, has provided various types of cracking furnace tubes and products, including long tubes, coils and key castings, to over a hundred domestic and international enterprises. The company's products fully cover the mainstream global ethylene cracking furnace technology routes, including typical furnace types developed by Lummus, Stone & Webster (SW), Technip FMC, Linde, Sinopec Engineering (SEI) and etc.
