style="text-indent:25px">用了這么多年，你真的懂鍍鋅無縫管么？1、鍍鋅無縫管表面存在的大小不一的灰**塊為鍍鋅色差，是目前鍍鋅行業(yè)的一個難題，主要與圓管本身所含的微量元素及鋅槽中成分有關(guān)。色斑并不影響圓管的防腐性能，**是美觀方面的差異。2、每根鍍鋅無縫圓管表面均有一條由細(xì)變粗，逐漸明顯的凸出的痕跡，該痕跡全部是鋅，是鍍鋅無縫管從鋅鍋中拿出后鋅液順管壁流下后冷卻凝固而成。3、每根鍍鋅無縫管靠近兩端出均有一個打磨噴漆的痕跡。無鏠管在熱浸鍍鋅時須固定在特制的鋼架上，并和鋼架一起浸泡在鋅液中，鍍鋅結(jié)束后,固定處會留下傷痕。為了美觀,該處會進行打磨并噴鋅。廣東低溫?zé)o縫管供應(yīng)結(jié)構(gòu)用無縫管是用于一般結(jié)構(gòu)和機械結(jié)構(gòu)的無縫管。</p><div

style="text-indent:25px">無縫管在市場是比較常見的設(shè)備，在市場上占據(jù)著非常重要的作用，消費者在選擇無縫管時可以直觀的看到的信息有哪些呢?1.材料。無縫管在選擇的時候可以直觀看到的信息首先就是材質(zhì)，無縫管的材質(zhì)上可以一眼看出的，具體的成分是無法知道的，但是在材料上可以一眼看出其材料是否優(yōu)越，在選擇的時候需要注意。2.質(zhì)量。無縫管的選擇可以直觀的看到的信息還有其質(zhì)量，在看的時候可以明顯的發(fā)現(xiàn)，如果是質(zhì)量優(yōu)良的無縫管，在外觀上一定非常的光滑，滿足使用上的需要，在光滑性上讓消費者滿意，做工精細(xì)。3.規(guī)格尺寸。優(yōu)良的無縫管還可以直觀的從外包裝上看到的就是規(guī)格尺寸，這一點也是非常重要的，在規(guī)格尺寸上的詳細(xì)對于無縫管的選擇非常重要，在選擇的時候需要注意這一點，優(yōu)良的規(guī)格尺寸是滿足使用需要的關(guān)鍵。綜上所述，對于優(yōu)良的無縫管，在選擇上，需要注意這些方面的關(guān)注，保證在選擇效果上得到滿足。</p><p style="text-indent:25px">無縫管多多少少都會有管壁厚不均勻的現(xiàn)象，這是生產(chǎn)工藝方式造成的，與技術(shù)高低無關(guān)。管壁厚不均勻會容易爆裂，特別是用于壓力管道、壓力容器方面。不銹鋼焊管就能解決這個問題，采用鋼材或鋼帶經(jīng)過機組和模具卷曲成型后焊接制而成；不銹鋼焊管擁有生產(chǎn)工藝簡單、生產(chǎn)效率高、管壁厚度均勻的優(yōu)點。隨著焊接和檢驗技術(shù)的進步，不銹圓管焊縫質(zhì)量不斷提高，焊接不銹圓管的品種規(guī)格日益增多，并在越來越多的領(lǐng)域尤其是在換熱設(shè)備用管、裝飾管、中低壓流體管等方面代替了無縫圓管。無縫管也完全走不出強勢行情，到底是什么因素制約著價格，還是要歸結(jié)于供需面來分析。</p><div

style="text-indent:25px">焊管從誕生那天起,就以其規(guī)則的外徑,均勻的壁厚,低廉的價格贏得人們的贊美。無數(shù)人為了把焊縫處理的完美無缺,付出了從超出常人的努力,甚至造出來"無縫化圓管"這一名詞。那么無縫管到底能不能被焊管代替呢?肯定是不能。焊管的抗H2S性能遠(yuǎn)遠(yuǎn)差于無縫管。NACE MR0175上對無縫管的要求是: S含量不得超過0.010%.但是對鋼板和焊管的要求就特別特別嚴(yán): S不得超過0.003%。焊管更難辦的事情是,雖然對鋼板嚴(yán)加要求,能通過HIC測試,但是焊縫要通過測試,目前還是很棘手的問題。不*要選擇優(yōu)良的焊材,還要有嫻熟的焊接工藝.SOMETIMES,還得另外做熱處理。很多石油公司的材料要求上對無縫管一般都豁免HIC測試.但是從鋼板,焊管,以及焊接管件從來沒有手軟過,不*要求HIC測試,很多情況下還要求加做SSC測試。專門用途的無縫管有鍋爐用無縫管、地質(zhì)用無縫管及石油用無縫管等多種。廣東低溫?zé)o縫管供應(yīng)</p><p
