螺旋鋼管在表面出現(xiàn)機(jī)械損傷以后，我們要進(jìn)行修復(fù)，一般情況下我們是采用什么樣的方法來進(jìn)行修復(fù)的呢?我們來了解一下吧!對(duì)于表面機(jī)械損傷一般采用加套的辦法加以修復(fù)，套由兩塊組成，兩條縱向焊縫由兩塊板條采用諾焊的辦法焊接。其優(yōu)點(diǎn)為在鋼管的本體上沒有焊縫?？v縫為帶襯板的對(duì)接焊縫，管體本身成為上下兩塊套的襯板。無論采用哪種方法.套必須緊箍在鋼管上。 </p> <p> 當(dāng)劃痕未造成泄漏時(shí)，套與螺旋鋼管管體之間的兩道環(huán)形角焊縫不必焊接，如泄漏時(shí)，則需焊上，這時(shí)套簡(jiǎn)直接承受液體造成的內(nèi)壓，因而，在這種情況下，套簡(jiǎn)的厚度一般不低于管壁厚。 </p><div style="width:100%;text-align: center;"><img
