列管式换热器管板焊缝检漏新方法及应用

A NEW DETECTING METHOD AND APPLYING OF TUBE SHEET WELD

列管式换热器管子与管板连接焊缝对换热器的安全使用和热效率的提高非常重要,对此焊缝的检验方法也很多。采用传统检漏方法对列管式换热器管子与管板连接焊缝进行检漏,程序烦琐且易造成误检、漏检。而使用新的检漏方法碳黑———煤油渗透法,不仅检漏效果好,而且速度快,具有推广应用价值。

The tube sheet weld of row tubing heat exchanger is vital to the safty usage and the improvement of efficiency.There are many ways to detect it.The traditional ways detecting for of leaks are vital and tend to make mistakes,As for the new detecting ways-Carbon-Kererson penetration,it is not only effective but also fast,which has expanding application value.
