管壳式换热器的管板与换热 管的连接常采用强度胀接。强度胀接适用于无剧烈振动,无过大温度变化及无严重的应力腐蚀的场合。GB151—89《钢制管壳式换热器》规定了强度胀管孔的结构和尺寸,如图1所示。符合要求的管孔是获得良好胀接接头的前提,而管孔内两条宽3mm,深0.5mm槽的加工是关键。下面介绍一种 Shell and tube heat exchanger tube plate and heat pipe connections often use the strength of expansion. Intensity expansion joint applies to no violent vibration, no excessive temperature changes and no serious stress corrosion of the occasion. GB151-89 “steel shell and tube heat exchanger” provides the strength of the structure and size of the expanded hole, as shown in Figure 1. Meet the requirements of the tube hole is to obtain a good prerequisite for expansion joints, and the tube hole two wide 3mm, 0.5mm deep groove processing is the key. Here’s a
