</p> <p> 行業(yè)分析師指出:受PVC完善的配套產(chǎn)業(yè)鏈以及國產(chǎn)原料支撐，2010年PVC管道產(chǎn)量占到了總量的55%。近些年，PVC管道市場受到各種因素的影響其市場份額在不斷的下降。而PVC管道市場份額下降主要有三大方面: </p> <p> 一是:PVC管道市場受到PE、PPR等其他塑料管道的沖擊，被搶占了一定的市場份額; </p> <p> 二是:含鉛穩(wěn)定劑在與食品類產(chǎn)品接觸的PVC管材中的禁用，對PVC管道的發(fā)展有一定的負面影響; </p> <p> 三是:當前，PVC管道發(fā)展處于高速發(fā)展期，行業(yè)產(chǎn)能不斷擴張，很多中小型企業(yè)為搶占市場，降低成本，在配方中大量填充碳酸鈣，以次充好，影響了PVC管道整個行業(yè)的形象，直接影響了PVC市場份額，加速了PVC市場份額的流失。 </p> <p> 但整體來看，雖然PVC管道份額在減少，但仍占據(jù)著塑料管道市場的霸主地位。并且塑料管道行業(yè)的誘人前景，仍是帶動PVC管道行業(yè)發(fā)展的一大亮點。四川穿線管日豐批發(fā)日豐PP-R管道系統(tǒng)由PPR管材、管件、閥門及相關配件構成。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">規(guī)格PVC給水管的規(guī)格尺寸有Φ20、Φ25、Φ32、Φ40、Φ50、Φ63、Φ75、Φ90、Φ110、Φ125、Φ140、Φ160、Φ180、Φ200、Φ225、Φ250、Φ280、Φ315、Φ355、Φ400、Φ450、Φ500、Φ630、Φ720、Φ800等。PVC給水管所示的壓力均表示為公稱壓力，用Mpa表示。公稱壓力規(guī)定為0.63Mpa、0.8Mpa、1.0Mpa、1.25Mpa、1.6Mpa等5種。每個壓力區(qū)的**小口徑的管材規(guī)定為:0.63Mpa管材的**小口徑為63mm，0.8Mpa管材的**小口徑為50mm，1.0Mpa管材的**小口徑為40mm，1.25Mpa管材的**小口徑為32mm，1.6Mpa管材的**小口徑為20mm和25mm。管材長度一般為4m、6m、8m，也可由供需雙方協(xié)商而定。折疊編</p><p> 1、安裝PP-R管道比較好找專業(yè)公司，(PPR管材管件要用實力大的品牌企業(yè)，一則品質(zhì)有保證，一則是一旦出現(xiàn)問題可以得到較好的解決方案)不管你的裝修多么豪華***，如果你在這方面不舍得用錢就不劃算了。往往管道的暴裂或者堵塞，都會造成水管本身價格數(shù)十倍、數(shù)百倍甚至不可估量的后果。 </p> <p> 2、安裝后一定要進行增壓測試。增壓測試一般是在1.5倍水壓的情況下進行,在測試中應沒有漏水現(xiàn)象。 </p> <p> 3、在沒有加壓條件下的簡單測試方法，但不完全可行。 </p> <p> 1) 關閉水管總閥。(即水表前面的水管開關) </p> <p> 2) 打開房間里面的水龍頭20分鐘，確保沒水再滴后關閉所有的水龍頭。 </p> <p> 3) 關閉馬桶水箱和洗衣機等具有蓄水功能的設備進水開關。 </p> <p> 4) 打開水管總閥。 </p> <p> 5) 打開總閥后20分鐘查看水表是否走動，包括緩慢的走動。建議配套使用日豐配件，(因為不同廠商的管子外徑與管件的內(nèi)徑會有偏差，容易造成焊接不良。</p><div style="width:100%;text-align: center;"><img

2:拿樣品摔，容易摔碎者一般是高鈣產(chǎn)品，當然要符合你們的要求價格合適的話是可以的。 </p> <p> 3:拿樣品用腳踩管材的邊，看看是否能裂開，或者裂開后的斷裂伸長率。(一般去試你得把管線先套好，哈哈，不然人家可不讓你踩) </p> <p> 4:耐侯方面。**直接的辦法就是拿到高溫高光的地方放個幾天，看表面變化率，但太浪費時間。主要看**項就好。折疊應用情況PVC管的本質(zhì)是一種真空吸塑膜，用于各類面板的表層包裝，所以又被稱為裝飾膜、附膠膜，應用于建材、包裝、醫(yī)藥等諸多行業(yè)。其中建材行業(yè)占的比重比較大，為百分之六十，其次是包裝行業(yè)，還有其他若干小范圍應用的行業(yè)。 </p> <p> PVC管用的時間長了有氯離子析出,不適合做自來水管,抗沖擊差,不適合做燃氣管道,但是PVC管價格低,硬度高,受氣溫影響熱漲冷縮小，所以PVC管分為PVC給水管和排水管兩種，用于市政給排水、工業(yè)給排水、民用給排水、灌溉、植被澆水等。熱水管試驗壓力，應為熱水管道系統(tǒng)設計壓力的2.0倍，不得小于1.2MPa。四川穿線管日豐批發(fā)</p><p

前景展望中國塑料管道生產(chǎn)能力達300萬噸，主要有PVC、PE和PP-R管道三大類，其中PVC管道是市場份額比較大的塑料管道，占塑料管道近70%的份額。PVC管材生產(chǎn)線1600余條。年生產(chǎn)能力250萬噸以上，2003年PVC管道(管件)年產(chǎn)量達120多萬噸。在塑料管道中，PVC的份額為70%， PE占25%， PP-R占4%，其它占1%。 </p> <p> 雖然PVC管道的快速發(fā)展吸引眾多企業(yè)進入這個行業(yè)投資，但在國內(nèi)生產(chǎn)眾多廠家(2000多家)中，年產(chǎn)能力在1萬噸的*有70多家，年產(chǎn)3萬噸以上的企業(yè)為20多家并擁有行業(yè)60%的產(chǎn)量。 </p> <p> 整體而言，國內(nèi)小口徑、低附加值的管道企業(yè)多，大口徑、高技術含量的企業(yè)少。PVC管材的加工能力分布存在結構性不合理。中小企業(yè)加工能力主要集中在PVC排水管，同時大量的非標管仍充斥市場，導致市場競爭無序而混亂。 </p> <p> <br /> </p> <p> <br /> 四川穿線管日豐批發(fā)</p></p><br /><p>文章來源地址:
