附录



一、工程量计算规则
一、除锈、刷油、防腐蚀工程
(一)计算公式
设备筒体、管道表面积计算公式:
S=π×D×L(1)
式中:π一一圆周率;
D一一设备或管道直径
L一一设备 筒体高或管道延长米。
(二)计算规则。
1.计算设备筒体、管道表面积时已包括各种管件、阀门、人孔、管口凹凸部分,不再另外计算;
2.管道、设备与矩形管道、大型型钢钢结构、铸铁管暖气片(散热面积为准)的除锈工程以“10m2”为计量单位;
3.一般钢结构、管廊钢结构的除锈工程以“100kg”为计量单位;
4.灰面、玻璃布、白布面、麻布、石棉布面、气柜、玛蹄脂面刷油工程以“10m2”为计量单位。
二、绝热工程
(一)计算公式
1.设备筒体或管道绝热、防潮和保护层计算公式:
V=兀×(D+1.03δ)×1.03δ×L(2)
S=π×(D+2.1δ)×L(3)
式中:D一一直径;
1.03、2.1一一调整系数;
δ一一绝热层厚度;
L一一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:D'一一伴热管道综合值;
D1一一主管道直径;
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(管径相同,夹角小于90°时)
D'=D1+D伴大+(10~20mm)(6)
式中:D'=伴热管道综合值
D1=主管道直径。
将上述D’计算结果分别带入式中(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]2×π×1.03δ×1.5×N(7)
S=[(D’+2.1δ)/2]2×π×1.5×N(8)
4.拱顶罐封头绝热、防潮和保护层计算公式:
V=2πr×(h+1.03δ)×1.03δ(9)
S=2πr×(h+2.1δ)(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V=π×(D+1.03δ)×1.03δ×L(11)
第二层至第N层D’=[D+2.1δ×(N一1)](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(m2)=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’=Di+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、防潮层粘接剂的厚度,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/T20553-2011选用。
