style="color:#E53333;">四川PE管</span></strong></a>在設計與安裝時(shí)也是需要遵循一定的規則的，具體有哪些呢？我們一起來(lái)看看！ </p> <p> 1、PE管道系統正常工作狀態(tài)下，選用的管材較大設計內水壓力（ Fwd），應按下式計算: Fwd=1.5Fw，式中Fw—管道工作壓力（不包括水錘壓力）。 </p> <p> 2、住宅小區、工業(yè)園區及工礦企業(yè)，公稱(chēng)外徑小于等于200mm的配水干管，可沿建筑物周?chē)贾?，在外墻（柱）凈距不宜小?.00m </p> <p> 3、聚乙烯埋地給水管管頂較小覆土深度，在人行道下不宜小于0.60mm，在輕型車(chē)行道下不宜小于1.00m </p> <p> <span style="text-indent:2em;">4、管道與建筑物、構筑物和其他工程管線(xiàn)之間較小水平凈距宜符合以下規定：</span> </p> <p style="text-align:center;"> <img src="/uploads/image/20180926/20180926193039_5312.jpg" alt="四川PE管" width="500" height="375" title="四川PE管" align="" /> </p> <p> 與建筑物間距：管道公稱(chēng)外徑小于等于200mm時(shí)為1.00m，公稱(chēng)外徑大于200mm時(shí)為3.00m； </p> <p> 與雨污水管間距：管道公稱(chēng)外徑小于等于200mm時(shí)為0.5～1.00m,公稱(chēng)外徑大于200mm時(shí)為1.0～1.50m； </p> <p> 與燃氣管間距：中低壓管為0.50m，高壓管1.0～1.50m；與電力電纜間距為0.50m； </p> <p> 與電信電纜間距為0.50m； </p> <p> 與喬木灌木間距為1.50m； </p> <p> 與通信照明電纜間距為0.50m； </p> <p> 與高壓鐵塔基礎間距為3.00m； </p> <p> 與道路側石邊緣間距為0.50m； </p> <p> 與鐵路坡腳間距為6.00m； </p> <p> 當上述間距難以保證時(shí)，應采取必要的安全技術(shù)措施。管道與熱力管道間的距離，應在保證聚乙烯管道表面溫度不超過(guò)40℃的條件下計算確定。較小不得小于0.5m。 </p>
