Centrifugal cast radiant coils for cracker by Qingdao Hexin Machinery Co., Ltd.
Centrifugal cast radiant coils for cracker by Qingdao Hexin Machinery Co., Ltd. The petrochemical cracking tube is suitable for cracking furnace (cracking furnace), which refers to the equipment used to carry out the cracking reaction of hydrocarbons. The requirement to the cracking furnace is: (1) the reactant can be quickly heated to 700～90CTC to ensure the equilibrium yield of ethylene, and heat supply and heat transfer need to be guaranteed; (2) the medium residence time is short, reducing the coke in the cracking process (3) suitable high temperature resistant materials. Due to the differences in the raw materials used for cracking and the method of providing the heat required for cracking, different types of cracking furnaces are used, such as regenerative cracking furnaces, sand furnaces and tubular cracking furnaces. The most widely used and the most mature technology is the tubular cracking furnace. In the past, the cracking tube generally used HK-40 alloy steel contain...
