style="text-indent:25px">80年始，歐洲供熱單位就開始選用預置保溫的塑料管道塑料管道系統(tǒng)代替鋼制管道，我國目前在部分地區(qū)的供熱單位已開使試用塑料管道系統(tǒng)（PE-RTⅡ），且試用情況良好。且在政策上鼓勵供熱系統(tǒng)上搞分戶供熱計量，進一步推動了塑料管道的推廣與使用。塑料管道作為埋地二次熱力管網的優(yōu)勢： ·以塑代鋼，節(jié)能節(jié)材； ·預置保溫管道，輸送過程中熱能損失小，節(jié)能； ·新型高分子化學建材，輸送熱水介質終生管道無腐蝕； ·使用壽命長達50年； ·環(huán)保綠色，材料可回收； ·施工工藝簡單，煙臺質量PE-RT II型管道報價、快速，系統(tǒng)密封性好； ·塑料管道柔性好，可以減少管件使用，降低施工成本。塑料埋地二次熱力管網的產品結構產品結構一般分為三層；內層為承壓塑料管道，煙臺質量PE-RT II型管道報價，要求具有優(yōu)異的高溫耐壓能力（如PE-RTⅡ管道）中間層為發(fā)泡保溫層（如PE+EVA閉孔發(fā)泡材料，或聚氨酯PU發(fā)泡），煙臺質量PE-RT II型管道報價。要求具有優(yōu)異的保溫性能，導熱系數(shù)可低至0.032W/mK 外層為保護層，為HDPE單壁波紋管或HDPE薄壁管。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="煙臺質量PE-RT II型管道報價"

2、PVC的強度優(yōu)于PE。聚乙烯比聚氯乙烯有更好的韌性（抗沖擊性）。聚乙烯可以在零下20度的溫度下使用（內部液體不能凍結并保持流動）。 </p> <p> 3、聚乙烯管采用熱熔連接，安全可靠，強度高；聚氯乙烯管采用膠粘劑或彈性密封圈連接，方便快捷。 </p> <p> 4、PVC管材成本低于PE管材，工程材料成本也較低。 </p> <p> 5、PVC管材配方復雜，添加劑較多。飲用水中的各種添加劑必須安全。聚乙烯管材添加劑少，一般衛(wèi)生性能優(yōu)于聚氯乙烯。 </p> <p> 6、PE-RTII型預制直埋保溫管較軟，小直徑管可卷制，聚氯乙烯管較硬，不能卷制。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="煙臺質量PE-RT II型管道報價" src="http://tyunfile.71360.com/UpLoadFile/2019/8/9/15/637009627405345172_qitaiwufeng_5787272.jpg"></div><p> 熱水管特性 </p> <p> 1、衛(wèi)生。PP-R的原料分子只要碳、氫元素，沒有有害的元素存在，不只用于冷熱水管道，還可用于純潔飲用水系統(tǒng)。 </p> <p> 2、較好的耐熱性。PPR管的維卡軟化點131.5℃。任務溫度可達95℃，可知足修建給排水標準中熱水系統(tǒng)的運用要求。 </p> <p> 3、保溫節(jié)能。PPR管導熱系數(shù)為0.21w/mk，*為鋼管的1/200。 </p> <p> 4、運用壽命長。PPR管在任務溫度70℃，任務壓力(P.N)1.OMPa前提下，運用壽命可達50年以上；常溫下(20℃)運用壽命可達100年以上。 </p> <p> 5、物料可收受接管應用。PPR廢料經潔凈、破裂后收受接管應用于管材、管件出產。收受接管料用量不超越總量10%，不影響產物質量。 </p> <p> 6、裝置便利。PP-R具有優(yōu)越的焊接功能，管材、管件可采用熱熔和電熔銜接，裝置便利，其銜接部位的強度大于管材自身的強度。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="煙臺質量PE-RT II型管道報價"
