今天和大家聊(liao)(liao)聊(liao)(liao)關于“金屬波紋(wen)管(guan)管(guan)坯(pi)的制(zhi)造(zao)工藝”：有(you)縫(feng)管(guan)坯(pi)的制(zhi)造(zao)，一般是選用所需(xu)厚(hou)度的板材(cai)或帶材(cai)，卷筒(tong)后對焊而成。有(you)縫(feng)管(guan)坯(pi)的質量，直(zhi)接取決于板（帶）材(cai)質量和焊接質量。一般來說，其壁厚(hou)公差(cha)較容易控制(zhi)。

金(jin)屬波(bo)紋(wen)管(guan)(guan)(guan)的(de)制(zhi)(zhi)造(zao)，是從選用原(yuan)材料(liao)開始，經過管(guan)(guan)(guan)坯(pi)制(zhi)(zhi)造(zao)、波(bo)紋(wen)管(guan)(guan)(guan)成形、整形、熱(re)處理(li)、表面處理(li)、質量檢驗等主要工藝(yi)環節，制(zhi)(zhi)造(zao)出符合設計(ji)要求的(de)波(bo)紋(wen)管(guan)(guan)(guan)。多(duo)層管(guan)(guan)(guan)坯(pi)的(de)套(tao)(tao)管(guan)(guan)(guan)，按照波(bo)紋(wen)管(guan)(guan)(guan)產品對層間質量的(de)要求不同(tong)，可采用硬態下(xia)(xia)套(tao)(tao)管(guan)(guan)(guan)和(he)軟態下(xia)(xia)套(tao)(tao)管(guan)(guan)(guan)兩種方法。

制(zhi)造(zao)(zao)完的(de)硬態管(guan)(guan)(guan)坯，清洗(xi)內外(wai)表面后(hou)，直接套管(guan)(guan)(guan)，然后(hou)進行固溶或者退火(huo)熱處理。無(wu)縫管(guan)(guan)(guan)坯的(de)制(zhi)造(zao)(zao)，要根據不(bu)同的(de)原(yuan)材料(liao)，采用不(bu)同的(de)工藝方法制(zhi)造(zao)(zao)。材料(liao)加工廠可提供(gong)壁(bi)(bi)厚0.1~0.3mm、外(wai)徑(jing)φ10~60mm的(de)不(bu)銹鋼薄壁(bi)(bi)無(wu)縫管(guan)(guan)(guan)。
