主要施工工艺设备和管线的保冷应在压力试验合格，外表面防腐全部完成后才能施工；设备保冷后铭牌应露出保冷层，其周围应做成斜面并密封，以防进水；设备保冷表面和其它临近构件（如：梯子平台的边缘和管线保冷层表面）的最小间距为 20mm；当保冷层厚度 80mm 时采用一层保冷材料，当保冷层厚度80mm 时应采用分层敷设，同层错缝，内外层压缝方式敷设，内外层接缝应错开100-150mm；为防止金属保护层因自重下滑，应将保护层与支撑圈用 512 的抽芯铆钉或自钻螺丝固定，间距不小于150mm；金属保护层的环向和纵向接缝应垂直排列整齐，并连接牢固。3.2.1 直管道保冷1、保冷层安装根据测量直管的实际尺寸确定聚氨酯瓦块的规格；聚氨酯瓦块内壁应紧贴管线壁；在瓦块之间的粘接处刷聚氨酯专用胶，然后将聚氨酯瓦块紧密套装在管线上，粘接牢固，饱满度达100%；环、纵缝及其他缝隙应为密闭、无空隙；瓦块的固定采用200.5 不锈钢带，绑扎间距应 500mm，且每块保冷层至少应在起止端各绑扎一次。2、防潮层的施工防潮层采用沥青玻璃布2 层；沥青玻璃布搭接应密实、连续，其环缝、纵缝搭接不得少于50mm，缝口朝下；搭接均匀、整齐美观；沥青玻璃布防潮层的厚度不得小于5mm，无气泡、翘口、脱层、开裂等缺陷，且应美观密实。3、复合花纹铝板保护层的安装测量安装保冷材料后的管线外径，确定复合花纹铝板的下料尺寸；根据下料尺寸用裁剪刀对复合花纹铝板下料；用压边机将下好的复合花纹铝板的纵缝搭接边压边成凸筋；精品资料-欢迎下载-欢迎下载名师归纳-第
