1. Pipeline anti-corrosion

　　(1)基本

　　(1) Basic treatment

　　黑套保溫管的底處理質(zhì)量直接影響防腐層的粘結(jié)質(zhì)量和防腐效果。目前常用的底層處理方法有噴霧解吸、化學解吸、化學解吸和化學解吸。野外常用的方法主要有噴發(fā)法和除銹法。

　　The bottom treatment quality of black sleeve insulation pipe directly affects the bonding quality and anticorrosive effect of anticorrosive coating. At present, the commonly used bottom treatment methods include spray desorption, chemical desorption, chemical desorption and chemical desorption. The common methods in the field are eruption and derusting.

　　(2)防腐結(jié)構(gòu)

　　(2) Anticorrosive structure

　　施工防腐涂料時，在雨、雪、風、沙等環(huán)境及相對濕度較大的情況下，沒有有效的施工方法。

　　During the construction of anticorrosive coating, there is no effective construction method under the conditions of rain, snow, wind, sand and relative humidity.

　　防腐涂層的類型應按規(guī)定分層。涂布厚度應均勻，無流動、起皺、針孔和空心滾筒缺陷。干燥后可采取保養(yǎng)方法。膠帶型涂料應嚴格使用。控制施工溫度，不要過熱。

　　The type of anti-corrosion coating shall be layered as specified. The coating thickness shall be uniform without flow, wrinkling, pinhole and hollow drum defects. After drying, maintenance methods can be taken. Tape type coating shall be strictly used. Control the construction temperature and do not overheat.

　　2. 管道保溫

　　2. Pipeline insulation

　　當黑套保溫管保溫層厚度大于100mm時，應分層。非水平管道的保溫結(jié)構(gòu)由下上，防潮層與維護層重疊部分向下壓緊，重疊寬度不小于30mm。

　　When the thickness of the insulation layer of the black sleeve insulation pipe is greater than 100mm, it shall be layered. The insulation structure of non horizontal pipeline is from bottom to top, and the overlapping part of damp proof layer and maintenance layer is pressed down, and the overlapping width is not less than 30mm.

　　安裝前對帶報警線的預制保溫管進行開關(guān)狀態(tài)及警戒線電阻值檢測。報警線的尺寸應符合貨物的要求，然后對管焊接。報警線應位于管道上方。一旦報警線受潮，應通過預熱或烘烤使其干燥。

　　Before installation, check the switch status and guard line resistance value of the prefabricated insulation pipe with alarm line. The size of the alarm line shall meet the requirements of the goods, and then the pipe shall be welded. The alarm line shall be located above the pipe. Once the alarm line is damp, it shall be dried by preheating or baking.

　　在進行絕緣工作之前，應在保證套管密封合格后，對直埋絕緣管的接口進行檢查。

　　Before the insulation work, the interface of the directly buried insulating pipe shall be inspected after the casing seal is qualified.
