pvc水管優(yōu)點1.具有較好的抗拉、抗壓強度：但其柔性不如其他塑料管。2.流體阻力?。篜VC-U管材的管壁非常光滑，對流體的阻力很小，其粗糙系數*為，其輸水能力可比同等管徑的鑄鐵管提高20%，比混凝土管提高40%。3.耐腐蝕性、耐藥品性優(yōu)良：PVC-U管材具有優(yōu)異的耐酸，耐堿，耐腐蝕，不受潮濕水份和土壤酸堿度的影響，管道鋪設時不需任何防腐處理。4.具有良好的水密性：PVC-U管材的安裝，不論采用粘接還是橡膠圈連接，均具有良好的水密性。5.防咬嚙：PVC-U管不是營養(yǎng)源，因此不會受到嚙齒動物的侵蝕。根據相關機構進行的試驗證明，老鼠不會咬嚙PVC-U管材。pvc水管的缺點Pvc水管柔性不如其他塑料管。熱穩(wěn)定性和抗沖擊性較差，無論是硬性還是軟質PVC使用過程中容易產生脆性。對人體會產生危害。PVC水管只能用于給排水用，無法用于熱水PVC水管的連接不能用熱熔工序，只能用PVC膠水進行連接PVC水管的運用：1：家裝領域的運用與PPR不同PPR主要用于上水管，而PVC只能用于下水管，除非預算有限，否則老金不建議在家裝領域用PVC水管，不過對于一些陽臺水龍頭(洗衣機）或廁所還是建議用PVC水管。家裝常用的PVC水管的規(guī)格有20mm/25mm/32mm三種規(guī)格，比較常用的顏色有灰色。</p><p> 長度6m、9m、12m及不定尺長度涂層壁厚100微米～500微米之間，通常為350微米。產品特性：1、衛(wèi)生無毒、不積垢，不滋生微生物、保證流體品質。2、耐化學腐蝕、耐土壤和海洋生物腐蝕，耐陰極剝離。3、安裝工藝成熟、方便快捷、與普通鍍鋅管連接雷同。4、耐候性好，適用沙漠、鹽堿等苛刻環(huán)境。5、管壁光滑、提高輸送效率、使用壽命長。常見的鋼塑復合管有：鋼襯聚丙烯復合管（），鋼襯聚氯乙烯復合管（），鋼襯聚乙烯復合管（），鋼襯聚四氟乙烯復合管（）。12襯塑鋼管可分為直縫焊管和螺旋焊管?？稍谙拦┧芫W中使用。具有強度高，抗應變能力強的優(yōu)點，但是其耐腐蝕性能差，應作防腐處理。同管徑的鋼管具有不同的厚度，所以在選擇的時候應注明壁厚。直縫焊管：生產工藝簡單，生產效率高，成本低，發(fā)展較快。螺旋焊管：強度一般比直縫焊管高，能用較窄的坯料生產管徑較大的焊管，還可以用同樣寬度的坯料生產管徑不同的焊管。但是與相同長度的直縫管相比，焊縫長度增加30~靠前，而且生產速度較低。因此，較小口徑的焊管大都采用直縫焊，大口徑焊管則大多采用螺旋焊。13鑄鐵管球墨鑄鐵管為鑄鐵管的一種，用作埋地敷設的給水管。其優(yōu)點是，和鋼管比價格便宜，制造簡易。按照樣板層不同戶型標準衛(wèi)生間的排水管道、管件；</p><div

5、不受余氯的影響：與聚烯烴管材不同，PVC-C管長期使用后，不受水中余氯的影響，不會出現裂痕和崩漏。6、耐酸堿：PVC-C不論對酸或對堿都有較強的防腐能力，可用作輸送HCL與NaOH液體。7、細菌不易繁殖：經過很多測試證實，PVC-C管內細菌不易孳生，其細菌增長率為PEX管的1/60，銅管的1/10，鋼管的1/4。其水樣中軍團菌數測試量為PEX管的1/13，PP-R管的1/17。8、低的熱膨脹系數和耐老化性能：相對其它塑料管來說，PVC-C管的熱膨脹系數較小，約為PP-R、PB和PEX等其他塑料管的1/2。PVC-C管具有較強的抗紫外線能力，可以在戶外使用，而一般的聚烯烴管不能。9、優(yōu)越的衛(wèi)生性能標準：PVC-C冷熱水管經許多國際性水質衛(wèi)生**機構的測試，其結果優(yōu)于世界衛(wèi)生組織及中華人民國家衛(wèi)生部等機構對飲用水方面的標準。9聚乙烯（PE）管PE管加工時不添加重金屬鹽穩(wěn)定劑，材質無毒性，無結垢層，不滋生細菌，很好地解決了城市飲用水的二次污染。除少數強氧化劑外，可耐多種化學介質的侵蝕；無電化學腐蝕。在額定溫度、壓力狀況下，PE管道可安全使用50年以上。PE管韌性好，耐沖擊強度高，重物直接壓過管道，不會導致管道破裂。PE管熱熔或電熔接口的強度高于管材本體。河北PVCPVC-U給水管哪家便宜</p></p><br
