pe給水管的(de)翻邊是什么？翻邊高(gao)度不一致怎么處理(li)？如何處理(li)翻邊？  

pe給(gei)水(shui)管(guan)(guan)的(de)(de)翻(fan)邊(bian)(bian)(bian)(bian)是管(guan)(guan)道(dao)焊(han)接過(guo)(guo)程(cheng)中(zhong)擠壓(ya)成(cheng)形的(de)(de)，通常稱(cheng)為內翻(fan)邊(bian)(bian)(bian)(bian)和外翻(fan)邊(bian)(bian)(bian)(bian)。翻(fan)邊(bian)(bian)(bian)(bian)質(zhi)量(liang)也影響pe給(gei)水(shui)管(guan)(guan)道(dao)的(de)(de)流動效率。如果(guo)翻(fan)邊(bian)(bian)(bian)(bian)過(guo)(guo)大(da)，容易產生結(jie)垢(gou)，導致管(guan)(guan)道(dao)內微生物(wu)生長。二(er)是在排(pai)水(shui)工程(cheng)中(zhong)，會產生泥沙淤積，降低水(shui)流效率。一(yi)般來(lai)說(shuo)，這是由(you)于(yu)pe管(guan)(guan)材端口(kou)不(bu)(bu)(bu)平整，受熱面積不(bu)(bu)(bu)均勻，必須重新熔(rong)(rong)化(hua)造成(cheng)的(de)(de)。在以往(wang)的(de)(de)pe給(gei)水(shui)管(guan)(guan)施(shi)工中(zhong)，暫時沒有很好的(de)(de)方(fang)法(fa)來(lai)處理內翻(fan)邊(bian)(bian)(bian)(bian)問(wen)題，這里(li)總結(jie)了PE管(guan)(guan)翻(fan)邊(bian)(bian)(bian)(bian)不(bu)(bu)(bu)合格的(de)(de)幾個原(yuan)因(yin)：翻(fan)邊(bian)(bian)(bian)(bian)過(guo)(guo)小：吸(xi)熱時間不(bu)(bu)(bu)足或(huo)(huo)焊(han)接機(ji)座(zuo)行程(cheng)不(bu)(bu)(bu)足；翻(fan)邊(bian)(bian)(bian)(bian)過(guo)(guo)大(da)：吸(xi)熱時間過(guo)(guo)長，PE給(gei)水(shui)管(guan)(guan)原(yuan)材料(liao)熔(rong)(rong)化(hua)過(guo)(guo)多；翻(fan)邊(bian)(bian)(bian)(bian)錯位：PE管(guan)(guan)未用(yong)水(shui)固(gu)定，或(huo)(huo)聚乙烯管(guan)(guan)熔(rong)(rong)口(kou)切割不(bu)(bu)(bu)順；         

pe給水(shui)管(guan)變形檢測(ce)(ce)與控制方法(fa)質(zhi)(zhi)量(liang)由每一個小細(xi)節(jie)決定。因此，本(ben)文根據(ju)自己(ji)的(de)(de)工(gong)(gong)作經(jing)(jing)驗(yan)，結合他(ta)人的(de)(de)經(jing)(jing)驗(yan)，總結了(le)(le)給排水(shui)用聚乙烯管(guan)施工(gong)(gong)中(zhong)不(bu)應(ying)出現的(de)(de)問題(ti)，詳細(xi)分(fen)析了(le)(le)原因，并(bing)(bing)提出了(le)(le)解(jie)決辦法(fa)。        pe給水(shui)管(guan)道變形檢測(ce)(ce)應(ying)在管(guan)道覆土夯實(shi)(shi)后進行(xing)，并(bing)(bing)在施工(gong)(gong)過程中(zhong)進行(xing)。施工(gong)(gong)變形，即短期展平率的(de)(de)試驗(yan)次數，一般應(ying)滿(man)足以(yi)下(xia)要求(qiu)：每一施工(gong)(gong)段(duan)最(zui)初50米不(bu)少(shao)于(yu)3次，并(bing)(bing)在點(dian)處進行(xing)管(guan)軸垂(chui)直裂縫縱橫(heng)直徑的(de)(de)表面測(ce)(ce)量(liang)；相(xiang)同條件下(xia)每100米不(bu)少(shao)于(yu)3次，取起(qi)點(dian)、中(zhong)點(dian)、接近終(zhong)點(dian)進行(xing)檢測(ce)(ce)，在地質(zhi)(zhi)條件下(xia)，當采用填(tian)料和壓(ya)力時(shi)，如有變化應(ying)測(ce)(ce)量(liang)實(shi)(shi)際工(gong)(gong)藝和管(guan)徑，重復上述檢測(ce)(ce)內容(rong)。對于(yu)允(yun)許的(de)(de)短期（24小時(shi)）壓(ya)扁(bian)率，HDPE大直徑塑料管(guan)的(de)(de)施工(gong)(gong)變形是實(shi)(shi)測(ce)(ce)的(de)(de)短期壓(ya)扁(bian)率應(ying)＜4%。
