河北316L不銹鋼盤管知識


組裝加工順序,    由于帶盤管、夾套的容器結(jié)構(gòu)特殊.因而組裝順序不同于其它容器.以下是在實(shí)際生產(chǎn)制造過程中總結(jié)出的一套可行的組裝方法:
    (1)組焊兩節(jié)內(nèi)筒.下封頭.劃出接廿孔位工及大小后焊縫進(jìn)行100%射線檢測Ⅱ級別合格。(在圖紙中接管孔位且處開小于圖紙接管孔的工藝孔.并焊接接管及法蘭以備水壓試驗(yàn)用).
    (2)將盤管及其緊固件(U形螺栓)、支抹件(角鋼)拋光處理后在外部組裝好.整休吊裝入內(nèi)筒.輝接固定。
    (3)出內(nèi)筒上封頭人孔,接骨孔線.開孔并組洋人孔組件、接份及接管法蘭與上封頭。

    (4)后組焊內(nèi)筒上封頭與內(nèi)筒,揮縫進(jìn)行100%射線檢測Ⅱ級別合格。

    (5)水壓試驗(yàn)1:安裝打壓工裝,對內(nèi)筒進(jìn)行1.0MPa水壓試驗(yàn)。水壓試驗(yàn)合格后.排凈內(nèi)筒中的水。
    (6)氣密性試驗(yàn)1:安裝打壓工裝.對內(nèi)筒進(jìn)行0.8Mpa氣密性試驗(yàn)。合格后切去試驗(yàn)用接竹及法蘭.切口處焊渣清理干凈。



河北316L不銹鋼盤管新聞


不銹鋼盤管在應(yīng)用領(lǐng)域,不銹鋼的優(yōu)勢更為明顯。由于不銹鋼是鋼中精品,具有不銹性、耐蝕性、美觀性和高強(qiáng)度、百分之百可回收等特性,山東不銹鋼盤管廠介紹在實(shí)際應(yīng)用中,可以進(jìn)一步顯現(xiàn)其節(jié)能減排的社會效益。例如,采用不銹鋼熱軋卷制造的新型不銹鋼貨車與采用普通碳鋼制造的國內(nèi)原通用敞車相比采用不銹鋼制造貨車車皮,可以降低初始鋼材消耗15%,整個(gè)生命周期可以降低鋼材消耗約55%。

    按照生命周期噸煤消耗鋼材測算,可以節(jié)約75%以上。這樣,每增產(chǎn)1噸不銹鋼,就可以替代4噸多碳素鋼。僅就不銹鋼制造過程與應(yīng)用過程節(jié)約鋼材這一因素綜合考慮,不銹鋼比普通碳鋼節(jié)約能源84.25%,減少CO2排放量87.16%。

      總而言之,不銹鋼是“節(jié)能減排”成效十分顯著的產(chǎn)品,是有利于避免“全球變暖、溫室效應(yīng)”的產(chǎn)品。我國先進(jìn)企業(yè)生產(chǎn)不銹鋼產(chǎn)品比其他國家和地區(qū)生產(chǎn)不銹鋼產(chǎn)品更有利于“節(jié)能減排”和避免“全球變暖、溫室效應(yīng)”。所以,我國大力發(fā)展不銹鋼產(chǎn)業(yè),不僅符合我國的國家利益,也符合全人類減少二氧化碳排放、避免“全球變暖、溫室效應(yīng)”的利益。


河北316L不銹鋼盤管簡介


不銹鋼盤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_坡口或加工焊接表面。焊接端口必須無缺陷,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,不銹鋼盤管內(nèi)需要充氬氣。具體做法是在焊前,將木制堵板加在盤管焊口的附近兩側(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)。流量過小,氬氣保護(hù)不好,焊縫背面容易氧化。流量過大,焊接時(shí)產(chǎn)生渦流帶入空氣,保護(hù)效果也會變壞,同時(shí)會引起焊縫的根部內(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。
