</p> <p> <br /> 湖南ppr聚氨酯保溫管生產(chǎn)廠家寧波萬里管道有限公司無論您選擇選擇哪款產(chǎn)品價(jià)格都是廠家直銷價(jià)，保障了客戶的利益！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江熱力聚氨酯保溫管規(guī)格,聚氨酯保溫管" src="http://tyunfile.71360.com/UploadFile/13386636601/637202360362441406/4007786.jpg"></div><p> 聚氨酯保溫管由工作管、聚氨酯硬質(zhì)泡沫和高密度聚乙烯外護(hù)管組成，聚乙烯外護(hù)管是聚氨酯保溫管的保護(hù)層。聚乙烯外護(hù)管采用高密度聚乙烯材料制成，具有極高的機(jī)械強(qiáng)度和優(yōu)良的耐腐蝕性能，可以保護(hù)管材在運(yùn)輸、安裝及使用過程中避免因外界因素而造成的破壞。制造外套管應(yīng)添加抗氧劑、紫外線穩(wěn)定劑和炭黑等。聚乙烯因優(yōu)異的耐磨性居塑料之冠，比尼龍66和聚四氟乙烯高4倍，比碳鋼高6倍，萬里管道選用聚乙烯材料制成外護(hù)管，在運(yùn)輸、工程安裝、后期維護(hù)中得到了有效保障。 </p> <p> <br /> </p><p> 聚氨酯保溫管中由于聚氨酯硬質(zhì)泡沫保溫層是緊密地粘結(jié)在鋼管外皮，隔絕了空氣和水的滲入，能起到良好的防腐作用。同時它的發(fā)泡孔都是閉合的，吸水性很小。高密度聚乙烯外殼、玻璃鋼外殼均具有良好的防腐、絕緣和機(jī)械性能。因此，工作鋼管外皮很難受到外界空氣和水的侵蝕。只要管道內(nèi)部水質(zhì)處理好，據(jù)資料介紹，使用壽命可達(dá)30年以上，比傳統(tǒng)的地溝敷設(shè)、架空敷設(shè)使用壽命高3到4倍。萬里管道在生產(chǎn)時，將防腐工藝，管件內(nèi)部元器件精細(xì)化處理，質(zhì)量可靠耐用+B54。 </p> <p> <br /> 聚氨酯保溫管防腐性能好，絕緣性能好，使用壽命長。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江熱力聚氨酯保溫管規(guī)格,聚氨酯保溫管"

聚氨酯保溫管的價(jià)格是怎樣定義的呢？一般聚氨酯保溫管在市場上的價(jià)格為80-100元每米,對于需要供暖聚氨酯保溫管的客戶來說,聚氨酯保溫管的價(jià)格影響因素是什么呢?我們一起來看下影響聚氨酯保溫管價(jià)格因素。 </p> <p> 對于供暖聚氨酯保溫管的價(jià)格而言,由于地區(qū)的經(jīng)濟(jì)差異,還有就是企業(yè)所在單位的地區(qū)差異,人員用工成本的差異,會導(dǎo)致我們的供暖聚氨酯保溫管的報(bào)價(jià)有所不同。同時品牌也會產(chǎn)生一定的影響，大家都知道,一個品牌的商品,它的成本也無形中比同類的其他產(chǎn)品高出一些。另外就是品牌產(chǎn)品的廠家規(guī)模都是很大的,一個大規(guī)模的工廠,無論在企業(yè)經(jīng)營還是在其他方面,所耗費(fèi)的資金平攤到我們的聚氨酯保溫管產(chǎn)品中,也是有一定的關(guān)系的。
