乙烯裂解炉对流段国产化制造技术

The Fabrication Technology About the Equipment of Convection Chamber in Pyrolyzer of Ethylene

介绍了乙烯裂解炉对流段的结构功能及其国产化制造技术质量要求和保证措施,包括配件制造、翅片管高频焊、炉管弯头对接焊、凸缘集箱骑缝焊、焊缝热处理、产品耐压试验、防护包装和运输等工序中需要注意的问题,特别是关于管件内表面质量的手指抚摸检测法、内置玻璃镜反射观察法及浇铸缺陷模型间接测量法均可确保管件进厂质量。

Structure function of convection chamber in pyrolyzer of ethylene and theirs internal fabrication quality requirement have introduced, such as fittings, finned tube, bend welding, box welding, past weld heat treatment, hydraulic pressure test, parking and shopping. Some special method can easy to find out the real situation and inspect the inside surface quality of fitting, such as tough and feel by finger, watch through the reflect ray by inside glass, casting and checking the model of lacuna on inside surface.
