[摘要]综述了换热器强度胀接接头缺陷产生的原因,从硬度差、材料、工艺等方面进行深入分析,并提出通过
热处理、换材料、控制间隙、液压胀接等方法进行改进措施。随着国内提倡“节能、环保”政策方针的推行,强度胀
接所具有的高效性、环保性、低成本性等优势,越来越引起国内厂家的重视。

Abstract: The thesis introduced the reason about defects happening from expanding tie-in of exchanging-heat instrument , analysis
from difference of rigidity,material, technics process, and put forward some improving measures such as heating treatment,changing
material,clearance contro,liquid-expanding, it followed the policy of “energy-saving, environment-protecting”advocated by our nation,the
high effect,protecting environment,and low cost of intensive -expanding have been recognized by some factories step by step.

在化工生产设备中,换热器占很大比例,约占设备投资的
1 基本技术指标
20 %~40 %;换热为化工最基本的单元操作,换热器完好与
否对化工生产影响巨大,而影响管壳式换热设备质量的重要因该设备为固定管板式换热器、其型号为 BEM
素之一是换热管与管板的连接接头质量。目前采用的连接接头 900--200-6/25
