—绝热层厚度;
—设备筒体或管道延长米。
2.伴热管道绝热工程量计算式:
1)单管伴热或双管伴热(管径相同,夹角小于90°时)
D = D1 + D2 +(10~20mm) (4)
式中: 一伴热管道综合值;
D1—主管道直径;
D2—伴热管道直径;
(10~20mm)—主管道与伴热管道之间的间隙。
2)双管伴热(管径相同,夹角大于90°时)
D = D1 + 1.5D2 +(10~20mm) (5)
3)双管伴热(管径不同,夹角小于90°时)
D = D1 + D伴大 +(10~20mm) (6)
式中: 一伴热管道综合值;
D1—主管道直径。
将上述 计算结果分别代人公式(7)、(8)计算出伴热管道的绝热层、防潮层和保护层工程量。
3.设备封头绝热、防潮和保护层工程量计算式:
V=[(D+1.033)/2]2x x 1.03 x 1.5 x N (7)
S=[(D+2.1 )/2]2x x 1.5 x
N (8)
4.拱顶罐封头绝热、防潮和保护层计算公式:

(10)
5.当绝热需分层施工时,工程量分层计算,执行设计要求相应厚度子目。分层计算工程量计算式为
第一层
(11)
第二层至第N层 D = [ D + 2.1 (N-1)] (12)

此表按下列公式计算:
1.体积(m3)=3.1415×(D+1.03δ)×1.03δ×L
2.面积(㎡)=3.1415×(D+2.1δ)×L
3.D管道外径;δ保温层厚度;L管道延长米;1.03、2.1为调整系数。
4.本表中数据是按无伴管状态考虑的如有伴管,则应将管外经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度时),则D’= D1+1.5D2+(10~20mm)。
③若双管伴热(管径不同,夹角小于90度时),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,(10~20)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、防潮层粘结剂的厚度,可按设计要求的厚度考虑增加。
5.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/T
20553-2011选用。
