工作含有鐵的聚氨酯保溫管一般分為三層。首層為工作鋼管層，根據(jù)設(shè)計(jì)和客戶的要求一般選用無縫鋼管、螺旋鋼管和直縫鋼管。第二層為氨酯保溫層。用高壓發(fā)泡機(jī)在鋼管與外護(hù)層之間形成的空腔中一次性注入硬質(zhì)聚氨酯泡沫塑料原液而成。第三層為密度聚乙烯保護(hù)層。其作用是保護(hù)聚氨酯保溫層,防腐、防水。如今,聚氨酯保溫管的應(yīng)用非常普遍,一些廠家在生產(chǎn)聚氦酯保溫管的時(shí)候在節(jié)能方面做了很大的改進(jìn)。以目前情況而言,聚氨酯保溫管的優(yōu)越性是任何保溫管道都難以比擬的。它保溫性能很好,節(jié)省了能源,占地面積少、工程造價(jià)低、施工周期短等優(yōu)點(diǎn)博得了廣大客戶的認(rèn)可。

聚氨酯保溫管需要供貨前需要進(jìn)行出廠檢驗(yàn)，保溫管岀廠前應(yīng)進(jìn)行以下出廠檢驗(yàn),檢驗(yàn)報(bào)告提交買方。鋼管在出廠前應(yīng)進(jìn)行靜水壓試驗(yàn),每段鋼管都應(yīng)在規(guī)定壓力下做靜水壓試驗(yàn)；接著鋼管的所有焊縫必須進(jìn)行***超聲波檢査和射線檢驗(yàn),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(jí)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(yàn),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。

聚氨酯保溫管也分很多種，我們?nèi)f里管道帶大家現(xiàn)在來了解一下聚氨酯保溫管具有怎樣的優(yōu)勢:聚氨酯直埋保溫管在用于供熱(供冷)工程上，其保溫密封效果較好，用于埋地敷設(shè)，不僅節(jié)約能源、減少浪費(fèi)，既不占地，又美化環(huán)境域。當(dāng)用在油氣輸送上、能滿足長輸要求，免去了運(yùn)行維護(hù)，大限度地滿足保溫防凍要求，減少加熱設(shè)備，降低了工程造價(jià)，且安裝特別方便，縮短工期。當(dāng)用于地?zé)?、溫泉輸送上，滿足降溫要求，實(shí)現(xiàn)長輸。用于水利、采礦傳統(tǒng)管道保溫的效果越來越差，因此對于北方地區(qū)而言，需要抗凍的地方，起不了抗凍的效果，極容易使管道損壞，這樣就又需要再次投入維修成本更換管道，而聚氨酯保溫管具有抗凍抗曬耐高溫，保溫管使用壽命長達(dá)30年，后期不用人工維修，代替了傳統(tǒng)的管道，萬里管道成為各種工程的指定產(chǎn)品。 </p> <p> <br /> 聚氨酯保溫管價(jià)格低、保溫效果好、制作工藝獨(dú)特，制作較為復(fù)雜，簡單模仿容易使質(zhì)量效果大打折扣。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

聚氨酯保溫管在安裝前需要進(jìn)行組對焊接，焊接后方可使用，在焊接時(shí)具有一定的規(guī)范，需要遵守且注意。以下是規(guī)范內(nèi)容： </p> <p> （1）焊件組對前及焊接前，應(yīng)將坡口及內(nèi)外側(cè)表面不小于20mm范圍內(nèi)的雜質(zhì)、污物、毛刺和鍍鋅層等清理干凈，并不得有裂縫、雜質(zhì)等缺點(diǎn)。 </p> <p> （2）管子及管件對接焊縫組對時(shí)，內(nèi)壁錯(cuò)邊量不應(yīng)超過母材厚度的10％，且不應(yīng)大于2mm </p> <p> （3）焊接時(shí)，選用的焊劑應(yīng)與母材和焊絲相匹配。 </p> <p> （4）焊縫位置應(yīng)符合如下規(guī)定：直管段上兩對接焊口中心面間的距離，當(dāng)公稱尺寸大于或等于150mm時(shí)，不應(yīng)小于150mm時(shí)；除采用定型彎頭外，管道焊縫的中心與管起彎點(diǎn)的距離不應(yīng)小于管外徑，且不應(yīng)小于100mm。管道焊縫間距支管或管接頭的開孔邊緣不應(yīng)小于50mm，且不應(yīng)小于孔徑；管道環(huán)焊縫距支、吊架凈距不得小于50mm。需熱處理的焊縫距支、吊架不得小于焊縫寬度的5倍，且不得小于100mm。

吊裝布管是聚氨酯保溫管進(jìn)入工程施工現(xiàn)場的首步，也是重要的一步。萬里管道施工規(guī)范要求吊裝布管時(shí)應(yīng)采用吊環(huán)吊裝，不得采用卡扣直接吊芯管或套管管口，以免變形。吊裝時(shí)應(yīng)采用布帶或其他不損傷外防腐得設(shè)備吊裝，嚴(yán)禁用鋼絲繩直接捆綁吊裝，以免損傷外防腐層。聚氨酯保溫管可單根吊入溝內(nèi)安裝，也可2根或多根組焊完后吊裝。當(dāng)組焊管段較長時(shí)，宜用兩臺(tái)或多臺(tái)吊車抬管下管，吊點(diǎn)的位置按平衡條件選定。應(yīng)用柔性吊帶起吊，并應(yīng)穩(wěn)起穩(wěn)效，嚴(yán)禁將管道直接推入溝內(nèi)。規(guī)范的吊裝能夠避免不必要的損傷，萬里管道長期遵守施工規(guī)范，質(zhì)量安全可靠。
