注:1.此表按下列公式计算:
V=π×(D+1.03δ)×1.03δ×L
S=π×(D+2.1δ)×L
D为管道外径;δ为保温层厚度;L为管道延长米;1.03、2.1为调整系数。
2.本表中的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若为单管伴热,则D’=D1+D2+(10~20mm)。
②若为双管伴热(管径相同,夹角大于90°时),则D'=D1+1.5D2+(10-20mm)。
③若为双管伴热(管径不同,夹角小于90°时).则D'=D1+D伴大+(10~20mm)。
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。
3.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/T205532011选用。
