對(dui)鋼波紋管有(you)用(yong)(yong)(yong)面積(ji)提出的(de)(de)要求及其核算(suan)方法取決于波(bo)紋管(guan)(guan)的(de)(de)用(yong)(yong)(yong)處。如(ru)果波(bo)紋管(guan)(guan)用(yong)(yong)(yong)作彈性密封件(jian)或管(guan)(guan)路熱補(bu)償時，有(you)用(yong)(yong)(yong)面積(ji)的(de)(de)意義僅在于用(yong)(yong)(yong)來核算(suan)波(bo)紋管(guan)(guan)成形時的(de)(de)軸向力(li)和運用(yong)(yong)(yong)系(xi)統(tong)中的(de)(de)推力(li)。波(bo)紋管(guan)(guan)的(de)(de)有(you)用(yong)(yong)(yong)面積(ji)核算(suan)值與實(shi)測(ce)值之(zhi)間急有(you)一些不(bu)同。

鋼(gang)波紋(wen)管(guan)

一般情況下(xia)用公式(shi)核算波紋管的有用面積(ji)，是可以(yi)滿意需要的。施(shi)工(gong)(gong)中嚴格執行三規(gui)(gui)則，即按規(gui)(gui)劃圖(tu)紙施(shi)工(gong)(gong)，按操(cao)(cao)作(zuo)規(gui)(gui)范(fan)操(cao)(cao)作(zuo)、按質量規(gui)(gui)范(fan)查看。在施(shi)工(gong)(gong)中如發現質量問題，應(ying)報(bao)請監(jian)理工(gong)(gong)程(cheng)師幫助處理，如工(gong)(gong)程(cheng)不能按規(gui)(gui)劃施(shi)工(gong)(gong)時，取(qu)得(de)規(gui)(gui)劃單(dan)位贊同，方可改變，且有規(gui)(gui)劃改變通(tong)知單(dan)。

In general, it is satisfactory to calculate the useful area of bellows with formula. Three rules shall be strictly implemented in construction, namely, construction according to planning drawings, operation according to operation specifications and inspection according to quality specifications. If quality problems are found in the construction, they should be reported to the supervision engineer for help. If the project cannot be constructed according to the plan, it can only be changed with the approval of the planning unit, and there is a notice of plan change.

模(mo)板(ban)運到施工(gong)現場后(hou)，要進(jin)行(xing)仿照試拼。試拼后(hou)仔細測量查看模(mo)板(ban)加(jia)工(gong)精度，對(dui)精度差的部分當(dang)地進(jin)行(xing)修整，尤其要注意單元塊間的結合部。如發現精度不能滿意規劃要求，退回嚴格整修。仔細做(zuo)好工(gong)序(xu)交(jiao)代(dai)作(zuo)業，每道(dao)工(gong)序(xu)完成后(hou)，經查看合格，方(fang)可進(jin)行(xing)下(xia)道(dao)工(gong)序(xu)，并做(zuo)好交(jiao)代(dai)記錄(lu)。

鋼波紋管

化學要(yao)素：介質(zhi)的(de)成分（包(bao)括(kuo)雜質(zhi)）、pH值、含氧量、可能發生(sheng)的(de)化學反應(ying)等(deng)。物理要(yao)素：介質(zhi)的(de)溫(wen)(wen)度(du)、流速、受(shou)熱(re)及散熱(re)條件、受(shou)力類型及大小等(deng)。特別(bie)要(yao)注意(yi)高溫(wen)(wen)、低溫(wen)(wen)、高壓、真(zhen)空(kong)、沖擊載荷(he)、交變(bian)應(ying)力等(deng)環境條件。

在防腐蝕結構規劃中，還要考慮結構及部件的形狀以及相互間的組合等是否符合防腐蝕，特別是避免各各類型部分腐蝕的要求。呈現質量事端要堅持在“三不放過”，即事端原因不清不放過，責任者沒有遭到教育不放過，沒有整改實施方法不放過。按技術交底準則，仔細做好工程質量交底作業。//hanihanbj.com/
