预制直埋复合(he)蒸汽(qi)保温管安(an)装注(zhu)意事项(xiang)

1.安装前检查(cha)管(guan)道规格等(deng)是否合适，埋设方(fang)法是否得当(dang)。埋设方(fang)法分为有偿直(zhi)(zhi)接埋设和(he)无偿直(zhi)(zhi)埋两种方(fang)式，要在安装前了解并选择适当(dang)的方(fang)法进行。

2.为保证(zheng)施工质量(liang)，要注意固定支架(jia)和井筒的(de)质量(liang)，如井筒防水(shui)效果，则会受到浸渍的(de)破坏。

3.在管(guan)道的安装中(zhong)要保(bao)障(zhang)焊(han)接(jie)的质量。

4.安装埋管(guan)时要注(zhu)意压(ya)(ya)(ya)力(li)的影响，可进(jin)行强度试(shi)验：管(guan)道内(nei)(nei)压(ya)(ya)(ya)力(li)提高到工(gong)作(zuo)压(ya)(ya)(ya)力(li)的1.5倍后(hou)，在10分钟(zhong)内(nei)(nei)没有(you)(you)泄(xie)漏；以及密封试(shi)验：当管(guan)道内(nei)(nei)压(ya)(ya)(ya)力(li)降(jiang)到工(gong)作(zuo)压(ya)(ya)(ya)力(li)时，焊缝受到1kg的锤击，30分钟(zhong)内(nei)(nei)没有(you)(you)泄(xie)漏，压(ya)(ya)(ya)降(jiang)不过0.2大(da)气压(ya)(ya)(ya)。

5.完成(cheng)压(ya)力试验(yan)、测量和(he)清洗后再进行回填。

6.由于管道埋在地下，是隐(yin)蔽工程，如竣工验收(shou)不严格，竣工数(shu)据不详细，对今后的使用(yong)有不利影(ying)响。
