</p> <p> <br /> </p><p> 聚氨酯保溫管采用直埋敷設(shè)時(shí)，需要將各個(gè)接口連接在一起，這個(gè)管件元器件叫做電熱熔套。電熱熔套由于采用了特種電熱絲網(wǎng)，結(jié)合部位的相當(dāng)理想,其連接強(qiáng)度和密封效果非常好，是國內(nèi)電熱熔套的更新?lián)Q代產(chǎn)品。電熱熔套是PE板材經(jīng)過彎折、覆網(wǎng)、打卷后通過電熱熔把夾克管連接在一起的一種連接管道的輔助件。熔化效果相當(dāng)理想。直埋管通過電熱熔套連接，連接強(qiáng)度高于母材、密封效果好、閉氣性能高、耐腐蝕、耐老化、施工方便快捷。萬里管道在聚氨酯保溫管接口時(shí)，常用電熱熔套進(jìn)行接口處理。 </p> <p> <br /> 聚氨酯保溫管使用聚乙烯外護(hù)管作為保護(hù)層，采用高密度聚乙烯材料制成，有良好機(jī)械強(qiáng)度和優(yōu)良的耐腐蝕性能。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

聚氨酯保溫管中的保溫層是用髙壓發(fā)泡機(jī)在鋼管于特制鋼模具之間形成的空腔中—次性注入硬質(zhì)聚氨酯泡沬塑料原液而成。即俗稱的“模具發(fā)泡工藝″。聚氨酯泡沬是否發(fā)滿,有任何質(zhì)量問題便于直接檢驗(yàn)。其作用一是防水,而是保溫,三是支撐熱網(wǎng)自重。當(dāng)輸送介質(zhì)溫度為:-50℃-120℃時(shí),選用硬質(zhì)聚氨基甲酸酯泡沬塑料做保溫層;當(dāng)輸送層。同時(shí)選用工作鋼管層時(shí),根據(jù)議計(jì)和客戶的要求一般選用無縫管螺旋焊管和直縫焊管。鋼管表面經(jīng)過先進(jìn)的拋丸除銹工藝處理后,鋼管除銹等級可達(dá)GB8923-1988標(biāo)準(zhǔn)中的Sa2級,表面粗糙度可達(dá)GB6060.5-88標(biāo)準(zhǔn)中R=125微米。鋼管表面除污除銹后涂刷層氰凝防腐材料,其作用是防水,二是改善保溫層與鋼管之間的粘接表面,使它形成—個(gè)整體。 </p> <p> <br /> 聚氨酯保溫管施工極其方便，使用綜合造價(jià)低，具有很強(qiáng)的耐腐蝕性能、很強(qiáng)的耐沖擊性能。重慶直埋聚氨酯保溫管標(biāo)準(zhǔn)</p><p style="text-indent:25px">聚氨酯保溫管的使用有效的解決了城鎮(zhèn)集中供熱中-50℃～120℃熱網(wǎng)管道中保溫、滑動(dòng)潤滑和管端的防水問題。廣西架空聚氨酯保溫管規(guī)格</p><p>
