S—電費單價（元/kW·h）；I—投資收益率（一般取6%～8%）；N—計算年限（可取30a或50a）；C—單位長度綜合投資（元/m）。凈現值法：凈現值法是考慮年運行費的時間價值，將工程年運行費用換算為現值，再與工程投資現值相加進行比較的方法。式中：W—費用總值（元）；C—管道工程建設總投資（元）；A—年運行費（元）；其余指標同前。目前，工程設計中采用年值法較多，該方法能較好地反映電費變動。3.工程實例某長距離輸水管道工程全長43km，由3段輸水線路組成，其中輸水干線，工程設計輸水流量m3/s，經綜合比較分析，確定選用球墨鑄鐵管作為輸水管材、單管輸水方案。根據工程總體布置方案，工程輸水須采用泵站加壓方式，在干線首端設加壓泵站1座。靜態(tài)法初選管徑在可研階段，采用靜態(tài)法初步確定經濟管徑，考慮到管道流速須滿足不沖不淤要求，取經濟流速為～，經計算分析，當取管徑為，管道流速，處于經濟流速范圍，初選管徑為。靜態(tài)法管徑計算過程見表1。動態(tài)法管徑確定在初設階段，采用動態(tài)法對輸水干線管徑方案進行深入比選分析，無論是采用年值法還是凈現值法，均需要對不同管徑的管道工程投資進行計算。資陽低壓輸水管價格PVC-M管道抗沖bai擊性可以達到PVC-U的五倍，但是造du價只有PE管的70%。</p><div

一桶能刷20㎡呢！剛才看到你的追問了，不錯，你問的那個人眼睛里除了鈔票，是不會回答你的問題的。內壁防腐要看管道的直徑，直徑太小了不能噴砂，只能采用酸洗的方法，在管道內壁達到GB8923-88的，就可以涂裝了，這個涂層配套你得自己選擇，一般要涂裝兩道底漆，每道底漆的厚度較少為40μm，然后你可以涂裝云鐵中間漆一道，當然也可以不要中間漆，一般中間漆的厚度為120μm，然后你可以直接涂裝環(huán)氧樹脂面漆兩道，一般的每道厚度為40μm。至于車間嘛！噴砂房、油漆房、行車就夠了，也不需要什么烘干房，除濕器什么的！祝太陽能熱水器的輸水管道外是否需要再套一個用來保護的塑料管如果說你有合適的管子的話包起來也可以，但是較好不要包，因為在夏季如果說露水了，在保溫帶（你說的海綿，實則不是）里，水是不容易蒸發(fā)的,到了冬天就更別提了,還是自然的好,那個東西對于日曬雨淋并不怎么損傷,沒關系的,你不可能十年都用這一個,到了要換的時候還是要換的,他的保溫效果會差下來的.如果說你有合適的管子的話包起來也可以，但是較好不要包，因為在夏季如果說露水了，在保溫帶（你說的海綿，實則不是）里。</p><p>
