标准SGSA0101-2002管架载荷计算规定实施日期2002年6月3日中国石化工程建设公司第1页共34页目次1总则2考虑承载的一般原则3重量载荷的确定4水平摩擦力的确定5热膨胀弹性力的确定1总则本规定适用于设计管架时计算管道重量载荷、弹性载荷及摩擦力。其余载荷如：风载、地震载荷等可根据需要按相应规定计算。2考虑承载的一般原则2.1当采用可变弹簧支吊架时，与其相邻的刚性支架的载荷应适当加大。一般取弹簧支吊架承受的最大载荷的15%作为转移载荷，作用在相邻刚性支架上。2.2对靠近泵，压缩机，汽轮机等敏感设备的支吊架，应能承受相应管段的全部重量。2.3计算安全阀排气管道上的支吊架载荷时（排气管口为T型的除外），尚应根据布置情况，考虑排气反作用力。排气反力按下式计算：KTQ(K+1)⋅MF=（2—1）273式中：F—排气管上气流的反作用力，kg；Q—气体或蒸汽排放量，kg/h；K—气体或蒸汽的绝热指数；T—安全阀入口绝对温度，K；SGSA0101-2002第2页共34页M—气体或蒸汽的分子量。3重量载荷的确定3.1重量载荷包括管道、管道附件、保温层材料、介质的重量（当介质比重小于1，且管道需进行水压试验时按充水重量考虑）。另外，根据需要考虑雪载荷等的作用。3.2由于管段形式和支承点所处位置不同，支吊架所承受的重量载荷亦不尽相同。为此，本规定将一般管段大致分为几种主要形式，分别采用以下简化方法计算支吊架重量载荷。3.2.1水平直管段3.2.1.1无集中载荷的水平直管段作用于管架上的重量载荷，按下式计算：L1L2RARBRCqR=L（3—1）A21qR=(L+L)（3—2）B212qR=L（3—3）C22式中：RA、RB、RC—分别为直管段作用于A、B、C管架上的重量载荷，kg；q—每米管道的重量，kg/m；L1、L2—管段长度，m。3.2.1.2带有集中载荷（阀门等）的水平直管段作用于两端管架上重量载荷按下式计算：SGSA0101-2002第3页共34页LabPRARBqP⋅bR=L+（3—4）A2LqP⋅aR=L+（3—5）B2L式中：P—集中载荷，kg；a、b—分别为集中载荷点至管架A、B的距离，m。3.2.2垂直L形管段作用于两端管架上的重量载荷，按下式确定。RA2LPbaL1RBL1aRA=q(L2+)+⋅P（3—6）2L1L1bRB=q⋅+⋅P（3—7）2L13.2.3Z形管段3.2.3.1水平Z形管段平面Z形管段作用于两端管架上的重量载荷，其计算公式比较复杂，为简化计算可利用作图法进行。作图步骤如下：先按比例画出AB管段各段长度，并在A、B两点间连直线，然后分别从L1、L2、L3各段的中点向AB引垂线，可分别得到a、b、c的长度，再将其代入式（3—8）和式（3—9），即可求出两支承点的载荷。SGSA0101-2002第4页共34页L3LR2L1RBabcLRA=q(L1⋅a+L2⋅b+L3⋅c)/L（3—8）RB=q(L1+L2+L3)−RA（3—9）3.2.3.2垂直Z形管段垂直Z形管段作用于两端管架上的重量载荷，按下式计算：aLR1bRBLLL⋅bR=q(+1)（3—10）A2LLL⋅aR=q(+1)（3—11）B2L3.2.3.3对于空间Z形管段两端管架的重量载荷，因计算复杂，简化法的结果误差过大，一般应采用电算法计算。3.2.4带分支的水平T形管段3.2.4.1分支管和主管在同一平面内的T形管段作用于管架上的重量载荷，按下式计算：SGSA0101-2002第5页共34页aL1(q1)RbL2(q2)RRCBq1L1q2⋅L2⋅bRA=+（3—12）22L1q1L1q2⋅L2⋅aRB=+（3—13）22L1qLR=22（3—14）C2式中：q1、q2—分别为主管、支管每米管道的重量载荷，kg/m。3.2.4.2分支管和主管不在同一平面内的T形管段，作用于管架上的重量载荷按下式计算：L2(q2)RahbL1(q1)RRCBq1⋅L1q2⋅bL2RA=+(+b)（3—15）2L12q1⋅L1q2⋅aL2RB=+(+h)（3—16）2L12SGSA0101-2002第6页共34页qLR=22（3—17）C2式中：h—分支管垂直段长度，m。3.3上述简化计算采用分段处理方法，所得的管架重量载荷系单侧计算值，由于一般管道均为连续敷设，故管架上的总重量载荷还必须加上相邻管段以该支承点上所作用的重量载荷。4水平摩擦力的计算作用于支托架上的水平摩擦力是在管道热位移时产生的，其大小与管道重量和接触面的材质有关。4.1托架上敷设单根管时，其水平摩擦力按下式计算：Pm=μ·Q（4—1）式中：Pm—水平摩擦力，kg；Q—作用于管架上的重量载荷，kg；μ—摩擦系数（见下表）。摩擦系数μ接触情况μ值钢与钢0.3滑动支架钢与混凝土0.6聚四氟乙烯与聚四氟乙烯0.1滚动支架钢与钢0.14.2支托架上敷设多根管时，其水平摩擦力按式（4-2a）和（4-2b）计算，取两者中之较大值：Pm=0.1ΣQi（4—2a）Pm=0.3Qmax（4—2b）式中：Pm—水平摩擦力，kg；QI—第i根管作用于管架上的重量载荷，kg;Qmax—管架上所支承管道中，最重管道的重量载荷，kg。5热膨胀弹性力的确定5.1因管段热胀作用于固定管架的弹性力，计算都十分复杂，为便于工程应用，本规定采用以下图表计算法。5.1.1根据管段形式按表1和与之相应的图表查出系数KX、KY和KZ。5.1.2根据管道操作条件和所用材料，由表16中查出相应之C值。SGSA0101-2002第7页共34页5.1.3按式（5-1），（5-2），（5-3）分别计算X、Y、Z三方向的热膨胀弹性力：IF=K⋅C⋅（5—1）XXL2IF=K⋅C⋅（5—2）YYL2IF=K⋅C⋅（5—3）ZZL2式中：FX、FY、FZ—分别为X、Y、Z方向上的弹性力，kg；KX、KY、KZ—分别为X、Y、Z方向上的系数（见表15）；C—膨胀系数（见表16）；L—相应管段计算参数，m；I—管子断面惯性矩，cm4πI=(D4−d4)64式中：D—管子外径，cm；d—管子内径，cm；SGSA0101-2002第8页共34页表1常见形状索引表类别图形表号FxFyL形2FyFxFxFy带钩3FyFxZ形FxFyFy4Fx带等长切线5FxFxL1=26LП2FyFyL1L27形L1带不等长切线FxFx=3L2L81=4LFy2Fy单边带切线9FxFxFy不等长腿Fx10FxFyFy等长腿11FxFy不等长腿单边FYRFxFx12带切线FYFx13二平Fx面形Fx带切线管F14xFxFz空间Z形15FyFyxFzSGSA0101-2002第9页共34页表2L形管段FyFxhFxLFyL/hKXKYL/hKXKY1.012.012.04.645636.21.217.212.54.851037.81.423.013.45.057039.51.632.014.45.263041.21.842.015.45.470043.02.054.016.65.677544.72.268.317.85.885546.22.484.419.26.093848.22.610320.66.2102049.82.812522.06.4111051.63.015023.56.6121253.43.217525.06.8131355.03.420726.57.0142656.83.623728.07.2151758.63.827429.57.4165560.24.031531.57.6178561.84.235633.07.8191763.64.440634.68.0205965.4SGSA0101-2002第10页共34页表3带钩的Z形管段FyFxFxL/2hFyLL/hKXKYL/hKXKY0.61.181.314.416040.40.82.72.24.617343.41.04.33.34.819846.41.27.84.75.021949.41.411.26.25.224152.51.615.27.75.426355.61.819.79.25.628658.72.024.310.95.831061.82.230.013.06.033465.02.437.015.16.236068.42.645.017.26.438871.82.854.019.36.641675.23.064.821.66.844678.93.276.024.07.047982.03.488.026.57.250885.53.6100.029.07.454089.13.8113.531.67.657992.74.0128.734.67.861596.34.2144.037.48.0653100.0SGSA0101-2002第11页共34页表4Z形管段FyaFxhbFxLFya/b→11.5234L/hKXKYKXKYKXKYKXKYKXKY0.69.2543.08.5387.3326.5256.0220.812.839.011.83510.5299.2238.5201.017.237.915.93414.42912.62211.8191.222.537.821.035182916.02314201.428.337.727362230202419211.635.442.134373032272524211.843.043.241393833342630222.052.845.750414635422740242.263.048.060435738512948252.476.051.071466840613158272.689.054.583497943713369292.810258.296539146823580303.011662.21105610449923790323.213266.0124591185110639104343.414970.0140631335412141118363.616874.0168661495713644132383.818878.0177701656015146147404.021082.0197731816316649163424.223586.421977201661855118244SGSA0101-2002第12页共34页续表4a/b→11.5234L/hKXKYKXKYKXKYKXKYKXKY4.426090.6241812216920453201464.628594.8263852417222356220484.831099.0287882637524358239505.0336103.2314922887826661260525.2364107.6341963138128663281545.4393111.83701003398531066304565.6425116.23991043658833568329585.8457120.54301083929236071355616.0491124.84611124229538673381636.2526129.44931164509841476408656.4562133.852612047810244379436676.6598138.250112450610547281465696.8633142.659812853510850284495727.0670145.063613256511153386526747.2715152.067413660111556589557767.4758156.571414063911859992588787.6803161.075614368012263394620817.8850165.579814872412566897655838.0898170.08401527701297039969485SGSA0101-2002第13页共34页表5П形—带等长切线管段ahFxLFxL/a→2345678910L/hKX1.02.402.462.522.58
