西安304/316l不銹鋼管換熱管主要用于火力發(fā)電、化工、鋼鐵等行業(yè)的加熱器更換304/316l不銹鋼管，冷油器更換304/316l不銹鋼管，冷水器更換304/316l不銹鋼管，取樣冷卻器更換304/316l不銹鋼管，抽氣冷卻器更換304/316l不銹鋼管，換熱器更換304/316l不銹鋼管，軸封加熱器更換304/316l不銹鋼管，高壓加熱器更換304/316l不銹鋼管，低壓加熱器更換304/316l不銹鋼管，壓力容器，空氣冷卻器等等。凝汽器(汽輪機凝汽器)304/316l不銹鋼管換熱管規格：直徑Ф12～Ф76mm，壁厚0.2～3.0mm，長(cháng)度分定尺和不定尺兩種。常用的材質(zhì)不銹鋼管型號有：304、304L、316、316L、317、317L。
西安304/316l不銹鋼管換熱管是引進(jìn)進(jìn)口制管設備制造而成，質(zhì)量與進(jìn)口不銹鋼管材相當或略強，焊縫金相組織與母材一樣，強度等機械性能略好。由于不銹鋼管帶材厚薄均勻，表面光滑平整，其質(zhì)量確比同種材質(zhì)的冷撥、熱軋無(wú)縫不銹鋼管好。延伸率大于35%，并且硬度小，易于脹接。
西安304/316l不銹鋼管換熱管分類(lèi)規格：不銹鋼光管,不銹鋼螺紋管,不銹鋼波紋管,201不銹鋼螺紋管,304不銹鋼螺紋管,316L不銹鋼螺紋管,不銹鋼U形管,不銹鋼翅片管等, 我公司自行開(kāi)發(fā)研制的不銹鋼管換熱管是選用進(jìn)口上等不銹鋼鋼管，不銹鋼帶材，冷拉、熱拉成形及帶鋼，經(jīng)過(guò)卷制、焊接、探傷、滾壓、打磨、固熔、拋光等一條龍304不銹鋼管、316L不銹鋼管生產(chǎn)線(xiàn)加工而成；可根據用戶(hù)的實(shí)際需要，生產(chǎn)不同管徑、壁厚、長(cháng)度形式等各種不銹鋼管規格的管材。
西安華達不銹鋼有限公司簿壁304/316l不銹鋼光管具有以下優(yōu)點(diǎn)：
1.凝汽器(汽輪機凝汽器)304/316l不銹鋼管換熱管傳熱性能好，由于不銹鋼管壁可采用0.5-0.7mm的薄壁不銹鋼管材，提高了整體換熱性能，在相同的換熱面積下，總體的304/316l不銹鋼管換熱管傳熱系數比銅管提高2.124-8.408％。
2.由于304/316l不銹鋼管換熱管材質(zhì)采用美國標準AISl304、316l等上等不銹合金鋼，使其具有較高的硬度，不銹鋼管子的鋼度也明顯提高。因此，具有很強的耐高溫蒸汽的沖擊性能及抗振性能。
3.由于304/316不銹鋼管子內壁光滑，使得其邊界層流底層厚度減薄，既強化換熱，又提高了抗結垢性能。
4.裝凝汽器(汽輪機凝汽器)304/316l不銹鋼管換熱管工藝性能好，采用傳統的脹管工藝，304/316l不銹鋼管換熱管外徑公差與銅管一致，不需改變管板孔的加工公差，利于現場(chǎng)直接選用，特別方便老機組的304/316l不銹鋼管換熱管更換管束改造。
5.304/316l不銹鋼管換熱管經(jīng)濟實(shí)惠，在同等換熱面積下，不銹鋼管的成本約為銅管成本的80％左右，并可直接進(jìn)行更換管束改造。
6.為了消除304/316l不銹鋼管換熱管焊接應力，在保護氣體中以1050℃高溫進(jìn)行熱處理。
7.所有304/316l不銹鋼管換熱管鋼管均采用壓差法進(jìn)行泄漏檢查，氣壓試驗至1.0Mpa，5分鐘無(wú)壓降。
