甲烷氯化物装置之脱污池出口管渗漏分析及改进

LEAKAGE CAUSE OF THE JOINT BETWEEN GRANITE AND POLYPIOPYLENE PIPELINE & IMPROVEMENT

经试验分析 ,花岗石脱污池体与聚丙烯出口管接缝处渗漏原因是两种材料的热膨胀系数有较大差别 ,经过更换出口管材 ,选择有效的密封粘接材料及连接形式 。

The leakage cause of the joint between granite and polypiopylene outlet in a chloromethane plant was analyzed. An improved method for effectively solving the leak problem of the joint between two kinds of materials with different expansion coefficients is presented.
