附录(一)

一、工程量计算公式:
(一)除锈、刷油工程量。
1.设备筒体表面积:S=π*D*L
式中π—圆周率;D—设备直径;L—设备筒体高。
(二)防腐蚀工程量。
1.设备筒体、管道表面积:S=π*D*L
式中π—圆周率;D—设备或管道直径;L设备筒体高或管道延长米。
2.阀门表面积:S=π*D*2.5D*K*N
式中D—直径;K—1.05;N—阀门个数。
3.弯头表面积:S=π*D*1.5D*K*2π*N/B
式中D—直径;K1.05;N—弯头个数;
B取定值为:900弯头B=4;450弯头B=8。
4.法兰表面积:S=π*D*1.5D*K*N
式中D—直径;K—1.05;N—法兰个数。
(三)绝热工程量。
1.设备筒体及管道绝热、防潮和保护层工程量:
V=π(D+1.033δ)*1.033δ*L
S=π(D+2.1δ+0.0082)*L
式中V—体积;S—表面积;D—直径;1.033、2.1—调整系数;δ—绝热层厚度;0.0082—捆扎线直径或钢带厚;L—设备筒体或管道长度。
2.设备封头绝热、防潮和保护层工程量:
V=[(D+1.033δ)/2]2*π*1.033δ*1.5*N
S=[(D+2.1δ)/2]2*π*1.5*N
3.拱顶罐封头绝热、防潮和保护层工程量:
V=2πr*(h+1.033δ)*1.033δ
S=2πr*(h+2.1δ)
4.伴热管道绝热工程量:
(1)单管伴热、双管伴热(管径相同,夹角小于90°时)。
D'=D1+D2+(10-20mm)
式中D'—伴热管综合值;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)
(3)双管伴热(管径不同,夹角小于90°时)。
D'=D1+D伴大+(10-20mm)
5.阀门绝热、防潮和保护层工程量:
V=π(D+1.033δ)*2.5D*1.033δ*1.05*N
S=π(D+2.1δ)*2.5D*1.05*N
6.法兰绝热、防潮和保护层工程量:
V=π(D+1.033δ)*1.5D*1.033δ*1.05*N
S=π(D+2.1δ)*1.5D*1.05*N
7.弯头绝热、防潮和保护层工程量:
V=π*(D+1.033δ)*1.5D*2π*1.033δ*N/B
S=π*(D+2.1δ)*1.5D*2π*N/B
B取定值为:90°弯头B=4;45°弯头B=8。
