| Abstract: | After operation of methanol circulation cooler for a period,three cracks occur on its pipe connection conic casing（ 1 longitudianl crack and 2 lateral cracks）. Through analysis from the chemical compositions of materials and the inner stress during the manufacture,the cases for the crack are found out and the preventive measures are proposed. |
