摘要
扬子石化公司扩建工程中，增建了一台目前亚洲最大的塔类设备─—二甲苯分离塔，其设计压力 １．０７ ＭＰａ，设计温度 ２０３～２５１℃，塔体采用日本 ＮＫＫ公司生产的耐焊接裂纹性能良好的高强度钢，配合使用极低氢型焊条。本文从焊接工艺的制定和焊接工艺试验方面进行了分析，并介绍了现场组焊施工管理经验。
A xylene separator, the biggest tower equipment in Asia so far, is set up in the extension project of Yangzi petrochemical corporation. The design operation pressure for the xylene separator is 1. 07 MPa and its design operation temperature is from 203 - 251 ℃. Tower body of the separator is a high strength steel with cracking resistance imported from NKK company of Japan. As to match this high strength steel for welding, an extremely low hydrogen welding rod is used for the welding process. This paper analyzes welding process and process test. It introduces the site welding construction and management as well.
