西安304/316l不鏽鋼管換熱管主要用於火力發(fā)電、化工、鋼鐵等行業(yè)的加熱器更換304/316l不鏽鋼管，冷油器更換304/316l不鏽鋼管，冷水器更換304/316l不鏽鋼管，取樣冷卻器更換304/316l不鏽鋼管，抽氣冷卻器更換304/316l不鏽鋼管，換熱器更換304/316l不鏽鋼管，軸封加熱器更換304/316l不鏽鋼管，高壓加熱器更換304/316l不鏽鋼管，低壓加熱器更換304/316l不鏽鋼管，壓力容器，空氣冷卻器等等。凝汽器(汽輪機(jī)凝汽器)304/316l不鏽鋼管換熱管規(guī)格：直徑Ф12～Ф76mm，壁厚0.2～3.0mm，長度分定尺和不定尺兩種。常用的材質(zhì)不鏽鋼管型號有：304、304L、316、316L、317、317L。
西安304/316l不鏽鋼管換熱管是引進(jìn)進(jìn)口製管設(shè)備製造而成，質(zhì)量與進(jìn)口不鏽鋼管材相當(dāng)或略強(qiáng)，焊縫金相組織與母材一樣，強(qiáng)度等機(jī)械性能略好。由於不鏽鋼管帶材厚薄均勻，表麵光滑平整，其質(zhì)量確比同種材質(zhì)的冷撥、熱軋無縫不鏽鋼管好。延伸率大於35%，並且硬度小，易於脹接。
西安304/316l不鏽鋼管換熱管分類規(guī)格：不鏽鋼光管,不鏽鋼螺紋管,不鏽鋼波紋管,201不鏽鋼螺紋管,304不鏽鋼螺紋管,316L不鏽鋼螺紋管,不鏽鋼U形管,不鏽鋼翅片管等, 我公司自行開發(fā)研製的不鏽鋼管換熱管是選用進(jìn)口上等不鏽鋼鋼管，不鏽鋼帶材，冷拉、熱拉成形及帶鋼，經(jīng)過卷製、焊接、探傷、滾壓、打磨、固熔、拋光等一條龍304不鏽鋼管、316L不鏽鋼管生產(chǎn)線加工而成；可根據(jù)用戶的實際需要，生產(chǎn)不同管徑、壁厚、長度形式等各種不鏽鋼管規(guī)格的管材。
西安華達(dá)不鏽鋼有限公司簿壁304/316l不鏽鋼光管具有以下優(yōu)點(diǎn)：
1.凝汽器(汽輪機(jī)凝汽器)304/316l不鏽鋼管換熱管傳熱性能好，由於不鏽鋼管壁可采用0.5-0.7mm的薄壁不鏽鋼管材，提高了整體換熱性能，在相同的換熱麵積下，總體的304/316l不鏽鋼管換熱管傳熱係數(shù)比銅管提高2.124-8.408％。
2.由於304/316l不鏽鋼管換熱管材質(zhì)采用美國標(biāo)準(zhǔn)AISl304、316l等上等不鏽合金鋼，使其具有較高的硬度，不鏽鋼管子的鋼度也明顯提高。因此，具有很強(qiáng)的耐高溫蒸汽的衝擊性能及抗振性能。
3.由於304/316不鏽鋼管子內(nèi)壁光滑，使得其邊界層流底層厚度減薄，既強(qiáng)化換熱，又提高了抗結(jié)垢性能。
4.裝凝汽器(汽輪機(jī)凝汽器)304/316l不鏽鋼管換熱管工藝性能好，采用傳統(tǒng)的脹管工藝，304/316l不鏽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，利於現(xiàn)場直接選用，特彆方便老機(jī)組的304/316l不鏽鋼管換熱管更換管束改造。
5.304/316l不鏽鋼管換熱管經(jīng)濟(jì)實惠，在同等換熱麵積下，不鏽鋼管的成本約為銅管成本的80％左右，並可直接進(jìn)行更換管束改造。
6.為了消除304/316l不鏽鋼管換熱管焊接應(yīng)力，在保護(hù)氣體中以1050℃高溫進(jìn)行熱處理。
7.所有304/316l不鏽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分鐘無壓降。
