常州超長(zhǎng)不銹鋼無(wú)縫盤(pán)管簡(jiǎn)介


不銹鋼盤(pán)管在焊接前首先管子材料必須采用機(jī)械加工的方法進(jìn)行管段截取,端面不可用燃?xì)飧畹堕_(kāi)坡口或加工焊接表面。焊接端口必須無(wú)缺陷,毛刺、碎屑應(yīng)清除,背面不得有倒角。接頭兩側(cè)20mm范圍內(nèi)氧化物必須清除干凈。必須采用專(zhuān)用不銹鋼刷子清除工作表面的氧化物(不銹鋼刷子不能在碳鋼上使用,以免產(chǎn)生污染)。其次,不銹鋼盤(pán)管內(nèi)需要充氬氣。具體做法是在焊前,將木制堵板加在盤(pán)管焊口的附近兩側(cè),形成隔離充氣小室(一般把堵板放在離焊口各100~150mm處),一端向充氣室充氣,并從另一堵板中心小孔出氣,為了減少管內(nèi)氬氣從對(duì)口間歇處流失,降低保護(hù)效果,焊接前可沿焊口間隙貼上膠帶,邊焊接邊揭去膠帶。為了補(bǔ)充氣室漏去的氬氣,焊接全過(guò)程都應(yīng)不間斷的向管內(nèi)充氬,氬氣流量應(yīng)適當(dāng)。流量過(guò)小,氬氣保護(hù)不好,焊縫背面容易氧化。流量過(guò)大,焊接時(shí)產(chǎn)生渦流帶入空氣,保護(hù)效果也會(huì)變壞,同時(shí)會(huì)引起焊縫的根部?jī)?nèi)凹等缺陷,影響焊接質(zhì)量。一般充氬流量控制在6~8L/min。另外應(yīng)特別注意的是,應(yīng)該在充氣時(shí)將充氣室或管內(nèi)空氣排凈后,焊接才能進(jìn)行,否則影響焊接質(zhì)量。局部充氣方法:堵板制作要求在焊接前將兩塊堵板事先放置于管子的兩側(cè),扣好繩子,焊接完成后,把兩塊堵板從管內(nèi)抽出。

常州超長(zhǎng)不銹鋼無(wú)縫盤(pán)管新聞


工業(yè)用不銹鋼盤(pán)管:熱交換器、鍋爐、石油、化工、化肥、化纖、制藥、核電等。
流體用不銹鋼盤(pán)管:飲料、啤酒、牛奶、供水系統(tǒng)、醫(yī)藥設(shè)備等。
機(jī)械結(jié)構(gòu)用不銹鋼盤(pán)管:印染、印刷、紡織機(jī)械、醫(yī)療器械、廚房設(shè)備、汽車(chē)與船舶配件、建筑與裝飾等。

不銹鋼光亮盤(pán)管:由不銹鋼帶焊接好再減壁,減壁由厚到薄,此過(guò)程可以使壁厚均勻,光滑,并且減壁拉伸管壁形成了無(wú)焊縫的效果.按照肉眼看是無(wú)縫管,但是其工藝決定是焊管.減壁的過(guò)程中伴隨光亮退火,使內(nèi)外壁不會(huì)形成氧化層,內(nèi)外光亮,美觀,這真是醫(yī)用產(chǎn)品所需要的。下道工序需要定徑,即大拉小工藝,確定外徑,外徑公差一般可以達(dá)到正負(fù)0.01mm.

焊接之后的修正工作
不銹鋼盤(pán)管焊接加工的同時(shí),焊接工藝所散發(fā)出的熱量是能夠?qū)е虏讳P鋼盤(pán)管變形的關(guān)鍵因素。不銹鋼盤(pán)管出現(xiàn)變形,對(duì)后續(xù)應(yīng)用出現(xiàn)非常大的影響,還會(huì)導(dǎo)致總體不銹鋼盤(pán)管物件實(shí)效,導(dǎo)致?lián)p失出現(xiàn)。因此,焊接不銹鋼盤(pán)管操作的過(guò)程中,不但要在準(zhǔn)備階段和操作階段隨時(shí)關(guān)心,防止變形情況出現(xiàn),操作結(jié)束之后,要不斷的修正不銹鋼盤(pán)管物件,保證正常使用。不銹鋼盤(pán)管物件焊接后的修正工作,可以從一定程度上修正焊接當(dāng)中帶來(lái)的變形影響,確保不銹鋼盤(pán)管正常良好使用。對(duì)不銹鋼盤(pán)管物件進(jìn)行后續(xù)修正工作,能夠降低焊接工藝帶給不銹鋼盤(pán)管的變形影響,可以確保不銹鋼盤(pán)管正常健康運(yùn)轉(zhuǎn),降低不銹鋼盤(pán)管的損失率,能夠有效的將經(jīng)濟(jì)和技術(shù)水平提高。 總之,焊接工藝對(duì)不銹鋼盤(pán)管焊接變形所帶來(lái)的影響無(wú)法避免,可是如果經(jīng)過(guò)專(zhuān)業(yè)人士良好的控制處理,也可以保證焊接件滿(mǎn)足焊接標(biāo)準(zhǔn),達(dá)到控制設(shè)備的需要。所以高水準(zhǔn)的專(zhuān)業(yè)人才,良好的管理工作不可或缺。
