一种钛-钢复合板制容器热气循环试验技术

A Hot Gas Circulation Test Technology of Titanium-steel Composite Plate Vessel

利用热气循环试验可以检测钛-钢复合板制容器的内部缺陷,评定其在实际操作工况下的可靠性。详细介绍了糠醛生产装置中TA10+Q345R容器热气循环试验的设计方案,主要包括试验压力、试验温度确定,升温、降温速率选择以及试验参数设计。实际热气循环试验中的压力为1.5 MPa、温度200℃,第1次平均升温速率11℃/h、平均降温速率7.74℃/h,第2次平均升温速率14.55℃/h、平均降温速率9.81℃/h,均低于相关技术文件中的规定。设计的试验方案可为同类钛-钢复合板制容器的热气循环试验提供技术参考。

The hot gas circulation test can detect the internal defects of the titanium-steel composite plate vessel and evaluate its reliability under actual operating conditions.The design scheme of the hot gas circulation test for TA10+Q345R vessel in the furfural production device was introduced in detail,including the test pressure,test temperature determination,heating and cooling rate selection and test parameter design.In the actual hot gas circulation test the pressure is 1.5 MPa and the temperature is 200℃.The first average heating rate is 11℃/h,the average cooling rate is 7.74℃/h.The second average heating rate is 14.55℃/h and the average cooling rate is 9.81℃/h,which are lower than the relevant technical documents.The designed test plan can provide a technical reference for the hot gas circulation test of similar titanium-steel composite plate vessels.
