What are the commonly used stainless steel tubes in the petrochemical industry

Petroleum refinery waste gas, natural gas or oil as raw materials, through a series of chemical reactions can be produced ethylene, propylene, acetylene, etc., and further synthesis can produce ethylene, polystyrene, acetone, butadiene, etc.. For the synthesis of the process is similar to the chemical industry, will be exposed to various types of acidic media, corrosive service environment is quite harsh, and the medium conditions change the magnitude of the larger range of materials used is also wide, involving the commonly used austenitic stainless steel: 304 stainless steel tube, 316 Stainless Steel Tube, 321 stainless steel tube, duplex stainless steel tube: 2205 stainless steel tube, 2507 stainless steel tube. Ferritic stainless steel tube: 430 stainless steel tube 410 stainless steel tube, iron-nickel-based corrosion-resistant alloy tubes and nickel-based corrosion-resistant alloy tubes: 625 corrosion-resistant nickel alloy tube, C-276 corrosion-resistant nickel alloy tubes, 825 corrosion-resistant alloy tubes and so on.
