現(xiàn)如今塑料管道發(fā)展迅速，以逐步替代了傳統(tǒng)的鋼鐵管材。pe管和ppr管是塑料管道中得到使用較多的兩種管材，它們也都常作為給水管道使用。它們之間有許多的區(qū)別，比方說它們在性能、焊接方法、強度、規(guī)格等方面都有很多不同的區(qū)別，下面讓我們一起了解下： </p> <p> 1、耐溫性能 </p> <p> PE管道在正常使用狀態(tài)下，高穩(wěn)定溫度為70℃，低溫度為-30℃。PPR管道在正常使用狀態(tài)下，高穩(wěn)定溫度為70℃，低溫度為-10℃。PE管與PPR管具有相同的耐高溫性能。但是低溫性能上PE管優(yōu)于PPR管。 </p> <p> 2、焊接 </p> <p> 雖然PPR管和PE管都能熱熔焊接，但是PPR管更容易操作，PPR管翻邊圓潤，而PE管翻邊不規(guī)則，容易堵塞；焊接溫度也有所不同，PPR管為260℃，PE管為230℃，西雙版納PE管材銷售價格。 </p> <p> 3、低溫沖擊強度 </p> <p> 從指標(biāo)上講是PE管材料的強項，西雙版納PE管材銷售價格，PPR管比PE管強度高，PE管比PPR管更柔韌。 </p> <p> 4、尺寸規(guī)格 </p> <p> PE管可以做的尺寸大規(guī)格為dn1000，PPR大規(guī)格為dn160，所以，西雙版納PE管材銷售價格，PE管用做排管的比較多，給水管一般都是PPR。 </p> <p> <br /> 選用管道生產(chǎn)廠家要以正規(guī)專業(yè)的生產(chǎn)廠家為準.西雙版納PE管材銷售價格</p><div

密封性能：PE具有良好的密封性能，不滲漏，滲漏率可以控制在1%之內(nèi)。RPM管道因其一般采用雙“O”型密封圈，另一般采用的12米RPM管道，輕微的角度變化即容易頂翻前部或后部膠圈，給安裝造成不必要的麻煩，也容易造成漏水。再有RPM管道施工規(guī)范規(guī)定，管線彎曲借轉(zhuǎn)角度不超過1度，因此管溝通輕微的不平或兩側(cè)壁較小的角度變化，即會導(dǎo)致接口借轉(zhuǎn)角超標(biāo)，形成漏水。 </p> <p> 流通能力：PE粗糙系數(shù)為0.009，內(nèi)壁光滑，水阻水，不結(jié)垢。夾砂管粗糙系數(shù)為0.01，內(nèi)壁不夠光滑，水流阻力大。 </p> <p> 通過一個比較詳細的對比，可以看到PE管相比玻璃鋼夾砂管來講更便于鋪設(shè)施工、密封性能更好、流通能力更強、日后的檢修也更加的方便。綜合多方面因素考慮，前者毫無疑問是更為理想的管材。西雙版納PE管材銷售價格PE礦用管在強腐蝕和高磨損條件下使用壽命是鋼管的4-6倍.著。</p><div style="width:100%;text-align: center;"><img

PE管較為常見的連接方式有熱熔對接和電熔連接兩種。熱熔對接中因操作不當(dāng)，常導(dǎo)致焊接接頭出現(xiàn)各種各樣的問題。 </p> <p> 1.標(biāo)準焊接接頭形式：接頭中間向下凹陷。且凹陷深度不超過管道表面，焊接接頭兩邊均勻、對稱。 </p> <p> 2.不對稱焊接接頭形式：主要是由于PE管兩邊加熱時間或加熱溫度不同形成的不對稱接頭或是由于焊接不同種材料的管道時，由于熔融溫度不同。加熱時間內(nèi)熔融塑料流動zhi數(shù)不同。 </p> <p> 3.窄而寬的焊接接頭形式：這是由于焊接壓力過大或者熔接時間過長導(dǎo)致的。 </p> <p> 4.較小的焊接接頭形式：PE管吸熱時間過短或?qū)訅毫^小，可能拖動壓力加入不正確或未加入拖動壓力就會有上述現(xiàn)象出現(xiàn)。 </p> <p> 5.接頭中心交界處產(chǎn)生了裂紋的接頭形式：由于加熱溫度不夠或切換時間過長，使得被焊接的塑料沒有充足的流動性，因而在焊接接頭中心交界處產(chǎn)生了裂紋。 </p><p> 灌溉用PE管的生產(chǎn)標(biāo)準？ </p> <p> 答：低密度聚乙烯灌溉用管材嚴格按照QB/T3803-1999《噴灌用低密度聚乙烯管材》標(biāo)準組織生產(chǎn)和檢驗驗收。 </p> <p> PE灌溉用管的優(yōu)勢？ </p> <p> 答：先進的機械構(gòu)造設(shè)計是采用平錐形單螺桿和科學(xué)獨特的壓縮比工藝設(shè)計和機械結(jié)構(gòu)之間形成統(tǒng)一完美的結(jié)合。具有二次排氣、重復(fù)壓縮、熔融適度和高速擠出生產(chǎn)加工的優(yōu)越性能。同時配有自動計量輸送，封閉無塵，混合分散均勻的混料設(shè)備，保障了生產(chǎn)加工自動化的連續(xù)性。在所有的工程塑料中HDPE的耐磨性居塑料之冠，**引人注目。</p><div

PE管能打多大壓力取決于它的管徑壁厚，另外打壓試驗是要滿足1.5倍的壓力要求。正常PE管試壓都是水壓，不需要排氣閥，爆管是不是壓力表準確，或者是在高溫的情況下打壓，一切排除就是管道質(zhì)量問題了！另外，PE管抗拉強度和壁厚沒什么關(guān)系，也沒有計算公式。PE管抗拉強度是受力后發(fā)生斷裂時單位面積上承受的比較大拉力?？估瓘姸燃幢碚鞑牧媳容^大均勻塑性變形的抗力，拉伸試樣在承受比較大拉應(yīng)力之前，變形是均勻一致的，但超出之后，金屬開始出現(xiàn)縮頸現(xiàn)象，即產(chǎn)生集中變形；對于沒有（或很?。┚鶆蛩苄宰冃蔚拇嘈圆牧希从沉瞬牧系臄嗔芽沽?。符號為Rm（GB/T

style="text-indent:25px">電熔連接焊口質(zhì)量問題 PE管電熔連接質(zhì)量問題主要是“假焊”。產(chǎn)生原因大致有六點： (1) 電熔套筒管件連接兩端PE管時未使用**固定夾具使兩PE管接口保持“同心”，強行拼裝造成接口間隙不均勻，接口熔接面積減少； (2) 電熔套筒管件與PE管材不屬同一生產(chǎn)廠家，管材與附屬器件存在兼容問題； (3) 未實施刮除氧化層作業(yè)或刮除不均勻，致使PE管端口部分產(chǎn)生不圓度，致使接口配合間隙不均勻，產(chǎn)生虛焊； (4) 在融合過程和冷卻時間內(nèi)移動連接件； (5) 為趕時間，冷卻過程未在自然狀態(tài)下進行，淋水或強制風(fēng)冷； (6) 管材插入電熔管件長度不足，可能造成脫焊。西雙版納PE管材銷售價格</p><p
