聲測(cè)管主要是由接頭和直管焊接在一起的，在進(jìn)行焊接的時(shí)候一定要注意以下幾點(diǎn)。1、焊條使用時(shí)應(yīng)保持干燥，鈦鈣型應(yīng)經(jīng)150℃干燥1小時(shí)，低氫型應(yīng)經(jīng)200-250℃干燥1小時(shí)(不能多次重復(fù)烘干，否則藥皮容易開裂剝落)，防止焊條藥皮粘油及其它臟物，以免致使焊縫增加含碳量和影響焊件質(zhì)量。樁基聲測(cè)管焊接時(shí)，受到重復(fù)加熱析出碳化物，降低耐腐蝕性和力學(xué)性能。焊后硬化性較大，容易產(chǎn)生裂紋。若采用同類型的焊條焊接，必須進(jìn)行300℃以上的預(yù)熱和焊后700℃左右的緩冷處理。若焊件不能進(jìn)行焊后熱處理，則應(yīng)選用鉻鎳不銹鋼焊條。2、為改善聲測(cè)管耐蝕性能及焊接性而適當(dāng)增加適量穩(wěn)定性元素Ti、Nb、Mo等，焊接性較好一些，采用同類型的鉻不銹鋼焊條時(shí)，應(yīng)進(jìn)行200℃以上的預(yù)熱和焊后800℃左右的回火處理。若焊件不能進(jìn)行熱處理，則應(yīng)選用鉻鎳不銹鋼焊條。要求控制曲率半徑。比如半徑長(zhǎng)度為，那么曲率半徑必須在所要求的公差范圍之內(nèi)。由于這些管件大多數(shù)用于焊接，為了提高焊接質(zhì)量，端部都車成坡口，留一定的角度，帶一定的邊，這一項(xiàng)要求也比較嚴(yán)，邊多厚，角度為多少和偏差范圍都有規(guī)定，幾何尺寸上比管件多了很多項(xiàng)。樁基聲測(cè)管表面質(zhì)量和機(jī)械性能基本和管子是一樣的。為了焊接方便。 </p><p style="text-indent:25px">要延伸高效聲測(cè)管的運(yùn)用壽命，根本的辦法是將塵埃擋在預(yù)聲測(cè)管。替換預(yù)聲測(cè)管一般無(wú)須停產(chǎn)，無(wú)須調(diào)試，所以有經(jīng)歷的業(yè)主會(huì)把注意力和金錢花在預(yù)聲測(cè)管廠家及維護(hù)級(jí)中級(jí)聲測(cè)管廠家上。關(guān)于10K級(jí)和100K級(jí)潔凈廠房，預(yù)過(guò)濾選用G4、中級(jí)可選用F8聲測(cè)管廠家(比色法95%)，這樣，結(jié)尾高效聲測(cè)管廠家的運(yùn)用壽命一般可達(dá)5年。在國(guó)外項(xiàng)目中和國(guó)內(nèi)新建項(xiàng)目中，F(xiàn)8聲測(cè)管廠家對(duì)錯(cuò)均勻流聲測(cè)管廠家常見的預(yù)聲測(cè)管廠家。有些場(chǎng)合，對(duì)高效聲測(cè)管廠家運(yùn)用壽命的規(guī)定不是出于對(duì)阻力的考慮，而是其它因素。若廠房中有氫氟酸，而車間空調(diào)又不是全新風(fēng)體系，高效聲測(cè)管廠家中的玻璃纖維濾紙會(huì)受到回風(fēng)的腐蝕，為了安全，有必要定時(shí)替換高效聲測(cè)管廠家。有些大的制藥廠，每年雨季往后要替換高效聲測(cè)管廠家，為的是避免聲測(cè)管廠家上任何或許的霉菌污染。有些生物實(shí)驗(yàn)室和與危險(xiǎn)品打交道的實(shí)驗(yàn)室，在開展一項(xiàng)新的重要課題前，為了可靠會(huì)要求運(yùn)用新的高效聲測(cè)管廠家。云南聲測(cè)管現(xiàn)貨供應(yīng)，云南貿(mào)軒商貿(mào)有限公司。</p><div
