钢管品种编制说明 

1   参数系列 

1.1  200MW及以下的机组参数 

管道参数系列保留《87典管》原有系列,同时增加次高压参数系列。根据目前火力发电厂的现有状况及发展趋势,即机组规模向高参数,大容量方向发展,200MW及以下的中小机组越来越少,并且经过多年运行实践,已经表明《87典管》中这部分机组的参数基本适用。对于次高压参数,由于在联合循环和CFB电厂有较多应用,因此本次修编将此参数系列补充进来。 

1.2  高压和超高压机组参数 

   原《87典管》中,高压和超高压机组的主蒸汽和热段设计温度为540℃,没有考虑锅炉出口的温度偏差,此次修编将此温度调整为545℃。 1.3  亚临界机组参数 

根据近些年国内已建、在建机组参数,经筛选后确定。该参数不考虑超压工况,并能覆盖较大的参数范围。对超出该参数的机组将按非常规参数特殊考虑。 1.4  超临界机组参数 

尽管超临界机组在我国已有数台投入运行,但参数相差较多。本《典管》是根据国产化超临界机组参数(沁北项目)来确定的。 2   管道材料 

此次典管修编,对于管道材料主要考虑两大系列即国产管材系列(GB系列)和国外管材系列。 2.1   国产管材 

2.1.1 Q215-A按《低压流体输送用焊接钢管》(GB/T3091-2001)选用。 2.1.2 20号钢按《低、中压锅炉用无缝钢管》(GB3087-1999)选用。 2.1.3 Q345钢按《输送流体用无缝钢管》(GB8163-1999)选用。 2.1.4 20G、15CrMoG、12Cr1MoVG按《高压锅炉用无缝钢管》(GB5310-1995)选用。 2.1.5 Q235-A按《螺旋缝埋弧焊钢管》(SY/T5037-92)选用。 2.1.6 0Cr18Ni9按《流体输送用不锈钢无缝钢管》(GB/T14976-94)选用。 2.2    国外管材 

国外管材的选用以满足四大管道设计为原则。 

2.2.1 美国管材 

主汽和热段:A335P91,A335P22,A691Gr.2 /4 CrCL22,A691Gr.91CL42 

冷段:      A672B70CL32, A106B, A335P11 给水:      A106B, A106C 

2.2.2 德国管材 

主汽和热段:F12,10CrMo910 给水:      st45.8/III, WB36 

3   尺寸系列 

所有的主蒸汽管道、热再热蒸汽管道和亚临界参数以上(包括亚临界参数)的主给水管道的尺寸系列按GB/T 1047-1995推荐的公称通径系列,根据“管道内径与公称通径最接近”的原则,靠各相应材料标准中的外径系列;为了保证管道与法兰的连接,其余

参数管道的尺寸系列按国家标准法兰(GB/T9112~9125-2000)的公称通径和外径系列。 4   钢管壁厚计算

sm―――直管的最小壁厚,mm; 

D0――― 管子外径,取用公称外径,mm; 

Y ――― 温度对计算管子壁厚公式修正系数,对于铁素体钢,482℃及以下时Y=0.4,

510℃时Y=0.5,538℃及以上时Y=0.7;对于奥氏体钢,566℃及以下时Y=0.4,593℃时Y=0.5,621℃及以上时Y=0.7;中间温度Y值,可按内插法计算; 

η―――许用应力修正系数,对于无缝钢管η=1.0;对于螺旋焊缝钢管,按SY/T5037

标准制造和无损检验合格者,η=0.9。 

α―――考虑腐蚀、磨损和机械强度要求附加厚度,mm; C ―――直管壁厚负偏差附加值,mm。 5     焊接对口方法以及坡口形式 

以往经常出现的管道与管道或管道与管件对焊的错口问题,为解决这一问题,我们参考了相关标准并结合国内钢管偏差的实际情况,对管道和管件都给出了一个基准值(焊接C值),以保证焊接要求。该焊接C值为推荐采用,工程中亦可依照具体情况采用其它的方法保证焊接要求。 6   主要管道规范

本次典管修编主要依据《管规》,同时也参考了一些国内外相关标准。在直管最小

壁厚的计算上,考虑了焊接基准值(焊接C值)对管道取用壁厚的影响,管道壁厚按相应的材料标准不仅考虑了壁厚偏差,而且考虑了管径偏差,因而一些管道的壁厚要比没有考虑焊接基准值的情况厚,请使用者注意。 

此外我们对普通无缝钢管,中高压汽水管道,腐蚀余度均取0mm,具体工程可按管道用途选择腐蚀裕度的取值;对于螺旋缝电焊钢管,壁厚裕度取2mm。对于GB5310及GB3087的钢管考虑到国产钢管的实际情况,在计算中我们对于其壁厚偏差以及外径偏差上是按普通级精度考滤。 8   管道标识编码说明
