此表按下列公式计算：
1．体积(m3)=3.1415×(D+1.033δ)×1.033δ×L
2．面积(m2)=3.1415×(D+2.1δ)×L
其中：D——管道外径：δ——保温层厚度；L——管道延长米；1.033、2.1为调整系数。
3．本表中数据是按无伴管状态考虑的，如有伴管，则应将管外径加上伴管直径及主管与伴管之间的缝隙。
①若为单伴，则D'=D1+D2+(10~20mm)；
②若双管伴热（管径相同，夹角大于90°时），则D'=D1+1.5D2+(10~20mm)；
③若双管伴热（管径不同，夹角小于90°时），则D'=D1+D伴大+(10~20mm)
其中：D'表示伴热管道综合值，D1表示主管直径；D2、D伴大表示伴管直径，(10~20mm)表示主管与伴管之间的缝隙。
④若伴热管道外增加铁丝网及铝箔，则应在管道综合值外增加双倍铁丝网及铝箔的厚度。
⑤若此表中没有考虑保冷时防滑剂的厚度、防潮层粘接剂的厚度，可按设计要求的厚度考虑增加。
4．本表内管道外径按《化工配管用无缝及焊接钢管尺寸选用系列》HG/T20553-2011选用。
