高壓厚壁管對(duì)接焊縫應(yīng)采用γ射線檢測(cè)，以提高檢測(cè)質(zhì)是和效率。由于進(jìn)行l(wèi)00%射線探傷，因此，管道預(yù)制除應(yīng)考慮預(yù)制深度及方便現(xiàn)場(chǎng)焊接外，還應(yīng)在固定口的預(yù)留上考慮探傷工作是否能進(jìn)行。焊縫返修，經(jīng)無損檢測(cè)判定為不合格的焊縫，必須認(rèn)真分析不合格原因，確保返修合格并不得超過3次。

<p> 不銹鋼無縫管的特點(diǎn) </p> <p> 其一、該產(chǎn)品的壁厚越厚，它就越具有經(jīng)濟(jì)性和實(shí)用性，壁厚越薄，它的加工成本就會(huì)大幅度的上升；其次、該產(chǎn)品的工藝決定它的局限性能，一般無縫鋼管精度低：壁厚不均勻、管內(nèi)外表光亮度低、定尺成本高，且內(nèi)外表還有麻點(diǎn)、黑點(diǎn)不易去除；其三、它的檢測(cè)及整形必須離線處理。因此它在高壓、**度、機(jī)械結(jié)構(gòu)用材方面體現(xiàn)了它的優(yōu)越性。 </p> <p> 不銹鋼管的種類 </p> <p> 接軋制方法分熱軋、熱擠壓和冷拔(軋)不銹鋼管。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山東201不銹鋼無縫管廠家現(xiàn)貨"
