</p> <p> （1）焊件組對前及焊接前，應將坡口及內(nèi)外側(cè)表面不小于20mm范圍內(nèi)的雜質(zhì)、污物、毛刺和鍍鋅層等清理干凈，并不得有裂縫、雜質(zhì)等缺點。 </p> <p> （2）管子及管件對接焊縫組對時，內(nèi)壁錯邊量不應超過母材厚度的10％，且不應大于2mm </p> <p> （3）焊接時，選用的焊劑應與母材和焊絲相匹配。 </p> <p> （4）焊縫位置應符合如下規(guī)定：直管段上兩對接焊口中心面間的距離，當公稱尺寸大于或等于150mm時，不應小于150mm時；除采用定型彎頭外，管道焊縫的中心與管起彎點的距離不應小于管外徑，且不應小于100mm。管道焊縫間距支管或管接頭的開孔邊緣不應小于50mm，且不應小于孔徑；管道環(huán)焊縫距支、吊架凈距不得小于50mm。需熱處理的焊縫距支、吊架不得小于焊縫寬度的5倍，且不得小于100mm。

聚氨酯保溫管是分三層的結(jié)構(gòu),這種管材有一層外保護層、還有一層保溫層和防滲漏層外保護層材料是玻璃鋼材料或者是聚乙烯材料,也可能是其他材料。這種管材的敷設方式有直埋的方式、架空的方式、以及少量采取地溝方式這樣的三種敷設形式。聚氨酯保溫管的應用十分普遍,這種管材目前被普遍應用在石油領域、化工領域、城區(qū)熱網(wǎng)等工程之中,適用的保溫范圍在-50℃—120℃的溫度,逐漸擴大,已經(jīng)達到了-70°—140°范圍,這種管材主要用在管道的保溫隔熱、容器內(nèi)熱介質(zhì)物料的保溫隔熱等。

聚氨酯保溫管中由于聚氨酯硬質(zhì)泡沫保溫層是緊密地粘結(jié)在鋼管外皮，隔絕了空氣和水的滲入，能起到良好的防腐作用。同時它的發(fā)泡孔都是閉合的，吸水性很小。高密度聚乙烯外殼、玻璃鋼外殼均具有良好的防腐、絕緣和機械性能。因此，工作鋼管外皮很難受到外界空氣和水的侵蝕。只要管道內(nèi)部水質(zhì)處理好，據(jù)資料介紹，使用壽命可達30年以上，比傳統(tǒng)的地溝敷設、架空敷設使用壽命高3到4倍。萬里管道在生產(chǎn)時，將防腐工藝，管件內(nèi)部元器件精細化處理，質(zhì)量可靠耐用+B54。
