聚氨酯保溫管的高密度聚乙烯外護(hù)管分為“一步法”和“兩步法”制作工藝，聚氨酯硬質(zhì)泡沫保溫層與外部保溫用高密度聚乙烯外護(hù)管（夾克管）一次成型的工藝，我們稱這為“一步法”，制作流程：鋼管除銹——鋼管防腐——聚氨酯發(fā)泡——成形——成品監(jiān)測——入庫。先生產(chǎn)出高密度聚乙烯外護(hù)層，然后在聚乙烯外護(hù)層與鋼管之間的空隙再澆筑聚氨酯硬質(zhì)泡沫塑料保溫層的制作工藝就是我們常說的“兩步法”。一步法適合生產(chǎn)管道在5000米甚至是10000米以上這種大批量而且單一品種的管道發(fā)泡，效率非常高。兩步法適合生產(chǎn)管道在幾百、數(shù)千米左右的訂單。

聚氨酯保溫管需要供貨前需要進(jìn)行出廠檢驗，保溫管岀廠前應(yīng)進(jìn)行以下出廠檢驗,檢驗報告提交買方。鋼管在出廠前應(yīng)進(jìn)行靜水壓試驗,每段鋼管都應(yīng)在規(guī)定壓力下做靜水壓試驗；接著鋼管的所有焊縫必須進(jìn)行***超聲波檢査和射線檢驗,檢査方法、合格標(biāo)準(zhǔn)及焊縫修補(bǔ)方法應(yīng)符合《石油天然氣工業(yè)輸送鋼管交貨技術(shù)條件第1部分:A級鋼管》GB/T9711.1的規(guī)定；然后保溫管外護(hù)管的密度、拉伸屈服強(qiáng)度、斷裂伸長率及保溫管外徑增大率按本技術(shù)規(guī)范的要求進(jìn)行檢驗,批合格判定按《髙密度聚乙烯外護(hù)管聚氨脂泡沫，只有經(jīng)過檢測合格的保溫管才能夠提交給買方，保證萬里管道質(zhì)量可靠。 </p> <p> <br /> </p><p> 聚氨酯保溫管生產(chǎn)后需要進(jìn)行驗收，驗收合格后方可交付給工程使用。進(jìn)場檢查：聚氨酯保溫兼防水材料具備兩重性能，材料進(jìn)場以后，必須對原材料進(jìn)行復(fù)試，復(fù)試主要內(nèi)容為材料的密度、壓縮性能、尺寸穩(wěn)定性、不透水性等；防水性能檢查：采用蓄水或雨淋的辦法檢查其防水效果，不得出現(xiàn)積水和滲漏水現(xiàn)象；噴涂厚度檢查：采用鋼針插入和量測的方法檢查厚度。經(jīng)過驗收檢查合格后，萬里管道生產(chǎn)的聚氨酯保溫管才可以出廠，保證工程施工質(zhì)量合格。 </p> <p> <br /> 聚氨酯保溫管的使用壽命除了生產(chǎn)廠家的質(zhì)量好壞外，施工質(zhì)量的差異也占了相當(dāng)大的比重。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江冷熱水聚氨酯保溫管推薦咨詢,聚氨酯保溫管" src="http://tyunfile.71360.com/UploadFile/13386636601/637202360384238281/3872577.png"></div><p> 聚氨酯保溫管在工程施工時，組對焊接是重要的一步，焊接的嚴(yán)密性保證了工作管的使用壽命。萬里管道聚氨酯保溫管在焊接工藝中根據(jù)成品管及成品管件的標(biāo)識進(jìn)行組對焊接，同時做無損檢測和強(qiáng)度試驗，焊接及無損檢測參照設(shè)計要求及國家規(guī)范進(jìn)行，工作管焊口要按照設(shè)計要求及國家規(guī)范做防腐，好的防腐可以延長管道的使用壽命。要注意的是在工作管接口時，不可割除工作管與外護(hù)管之間的定位支撐或擋水板等臨時固定件，臨時固定件需等到焊接完畢后才能拆除。 </p> <p> <br /> 萬里管道的聚氨酯保溫管可以滿足連續(xù)工作溫度不超過140℃的流體介質(zhì)輸送應(yīng)用。浙江冷熱水聚氨酯保溫管推薦咨詢</p><p style="text-indent:25px">聚氨酯保溫管的保質(zhì)層化學(xué)名叫聚氨酯硬質(zhì)泡沫，強(qiáng)度高，吸水率低，保溫效果好，在管道保溫中得到了應(yīng)用。浙江冷熱水聚氨酯保溫管推薦咨詢</p><p> 有時聚氨酯保溫管需要輸送一些特殊介質(zhì)時，需要在一定的壓力下，需要工作管擁有的鋼度及強(qiáng)度較強(qiáng)。這時我們應(yīng)選用鋼塑復(fù)合管作為工作鋼管，其保留了傳統(tǒng)金屬管材的鋼度及強(qiáng)度，遠(yuǎn)遠(yuǎn)優(yōu)于塑料管、鋁塑管。同時具有內(nèi)壁光滑、磨擦阻力小不結(jié)垢的特點，外壁更加美觀豪華；重量輕、韌性好、耐沖擊、耐壓強(qiáng)度高；適用溫度更寬-30℃～100℃；與管件連接方式可采用絞絲、承插、法蘭、溝槽、焊接等，多種方式、省工省力；與管件連接部位熱膨脹系數(shù)差小，更安全可靠；價格性能比合理，綜合造價低、比銅管、不銹鋼管更經(jīng)濟(jì)。但鋼塑復(fù)合管的生產(chǎn)工藝比較復(fù)雜，使得許多管材廠家望而卻步，而萬里管道能夠使用鋼塑復(fù)合管作為工作鋼管，技術(shù)優(yōu)勢明顯，性能遠(yuǎn)超其他管道。
