2、低温钢焊接规程（SH352592）；（6）钛管施工及验收规范（SHJ50286）；（7）工业金属管道工程施工及验收规范（GB5023597）；（8）钢制管法兰、垫片、紧固件（HG205922063597）；（9）石油化工安装工程概算指标编制说明（1993年版）；（10）化工、化肥工程项目施工图设计文件。2指标的特点（1）指标的表现型式：化工工艺管道指标分为概算指标和主材费两部分，概算指标以“10米”(延长米)为计算单位；主材费以“吨”为计算单位。（2）本次修订取消了铅管、铸铁管、硅铁管的概算指标内容。中低压无缝碳钢、铬钼钢、不锈钢管道增设了以下特殊类别管道概算指标：毒性程度为剧毒介质管道、温度

3、低于29的低温管道和压力大于等于4MPa且温度大于400的高温管道，特殊管道概算指标在其名称及规格后标注“”符号，以示和相同规格的一般管道区分。拌热管分不同材质分别设置一个碳钢伴热管、不锈钢伴热管安装子目。修订后概算指标的管道规格力求与预算定额保持一致。3工程量测算、取定及指标合成（1）根据最近几年国内、国外设计的7套化工、化肥装置施工图设计文件，对管道、管件、法兰和盲板等按不同材质、介质、压力等级、规格进行工程量统计汇总。对每10米长管道所包含的管件、法兰、盲板等进行了综合取定，取定结果见附表212“低压无缝碳钢管管件10米含量取定表”，附表213“中压无缝碳钢管管件10米含量取定表”，附表

4、215“中、低压铬钼钢管管件10米含量取定表”，附表218“中、低压不锈钢管管件10米含量取定表”。除了上述管件含量取定表外，其它管道管件10米含量取定表是在概算指标（91年版）“管件吨含量取定表”的基础上，折算得到，并对部分管件及含量作了必要的修改、调整。10米（延长米）管道管件含量取定表见附表2112115。（2）各种管材和管件的壁厚按照石油化工行业安装工程预算定额（1999版）取定，综合取定壁厚见附表2116，指标的合成依据现行施工规范要求进行，各类管道组合内容见附表2-1-17。（3）根据国标工业金属管道工程施工及验收规范（GB502351997）和中国石油化工总公司石油化工剧毒、可燃

12、毒、可燃介质管道工程施工及验收规范（SH35011997）中列出的常用剧毒介质名称：极度危害：汞及其化合物、砷及其无机化合物、氯乙烯、铬酸盐、重铬酸盐、黄磷、铍及其化合物、对硫磷、羧基镍、八氟异丁烯、锰及其无机化合物、氰化物。高度危害：三硝基甲苯、铅及其化合物、二硫化碳、氯、丙烯腈、四氯化碳、硫化氢、甲醛、苯胺、氟化氢、五氯酚及其钠盐、镉及其化合物、敌百虫、氯丙烯、矾及其化合物、溴甲烷、硫酸二甲酯、金属镍、甲苯二异氰酸酯、环氧氯丙烷、砷化氢、敌敌畏、光气、氯丁二烯、一氧化碳、硝基苯、苯。（4）空分装置管道安装套用本指标时，应乘以以下系数：中压无缝碳钢管道乘以0.80；高压无缝碳钢管道乘以0.6

13、0；无缝不锈钢管乘以0.60。空分装置其他管道施工费不作调整。（5）空压装置及冷冻站管道安装可直接套用本概算指标，施工费不作调整。（6）全厂工艺及供热外管安装套用概算指标时，应乘以以下系数：碳钢管道乘以0.60；不锈钢管道乘以0.55。（7）超低碳不锈钢（304L、316L）管道安装套用相应不锈钢管道概算指标时，应对施工费进行调整：中低压超低碳不锈钢管道乘以1.12；高压超低碳不锈钢管道乘以1.08。（8）卷管统一按外购成品件考虑，其制作费用未进入概算指标中。（9）低合金钢管道如16Mn、15MnV等套用碳钢管道概算指标。（10）铬钼钢管道概算指标适用于Cr5Mo、15CrMo、12CrMo等

14、铬钼钢管道。（11）铜管道概算指标适用于紫铜管道和黄铜管道。（12）铝管道概算指标适用于各种铝管道和铝合金管道。三、主材费1主材费的表现形式为了解决管道壁厚对主材费的影响，主材费以“吨”为计算单位与概算指标分离。公称直径相差不大的管道主材费比较接近，低压管道与中压管道主材费比较接近，因此，低压管道与中压管道、公称直径相差不大的管道取定一个主材费实物量及综合价格。化工工艺管道参考主材费共分为三部分：主材费；主材费实物量及综合价格；主材综合实物量及基础价格。2主材费的合成主材综合实物量是形成主材综合价格的材料量。主材综合实物量取定是对附表21116进行折算加权取定得到。基础价格是指具有一定名称、规

15、格的材料单价。管材、管件、法兰、支吊架基础价格根据中国石油化工集团公司工程定额管理站提供的价格资料、收集到的材料价格及管件、法兰的单重计算取定得到。主材费实物量是在主材综合实物量的基础上合并相加得到。综合价格是主材综合实物量乘以基础价格后相加，再除以主材费实物量得到。主材费是主材费实物量乘以综合价格相加后，再乘以1.02得到。其中2%是指盲板、紧固件、垫片等的材料费。3主材费的使用方法在工艺管道概算编制中，主材费的计算最好根据设计提供的材料量乘以材料市场价格直接计算。也可以根据相应的概算指标编号，直接套用主材费。主材费使用中应注意以下内容：（1）全厂工艺及供热外管套用主材费后，需对主材费乘以以

16、下系数：碳钢管道乘以0.68；不锈钢管道乘以0.60。（2）空分装置管道套用相应的主材费后，应分别对主材费乘以以下系数：中压无缝碳钢管道乘以0.85；高压无缝碳钢管道乘以0.60；无缝不锈钢管道乘以0.65；空分装置其他管道主材费不作调整。空压装置及冷冻站可直接套用主材费，不作调整。（3）不锈钢管道主材费适用于18-8、304等，超低碳不锈钢管道套用相应的不锈钢管道主材费后，主材费应乘以以下系数：304L乘以1.4，316L乘以1.55。（4）低温钢管道套用相应的碳钢管道主材费后，应按如下方法调整：（低温钢管道管材单价/碳钢管道管材单价）碳钢管道主材费=调整后的低温钢管道主材费（5）铝管道主材

17、费适用于纯铝管道、铝合金管道，铜管道主材费适用于紫铜管道、黄铜管道，套用主材费时不作调整。附表211 焊接钢管管件10米含量取定表序号名称单位公称直径（毫米）15202532405065801001251501管道米10101010101010101010102弯头个4.934.932.982.982.682.791.611.611.471.471.473三通个2.562.562.902.912.642.641.171.171.121.131.134活接头个1.351.350.730.730.390.390.360.365内接头个0.260.260.250.250.010.010.010.01
