插条不能明显偏斜,开口缝应在中间,不管插条还是管端咬口翻边应准确、压紧,以后连接接头才会整齐、贴紧。
The not significant deviation, open seams should be in the middle, or whether cutting pipe end bite flange should be accurate, pressing, after the joint will be neat, close.
当温度变化时管子能在接头中间自由的伸缩,当地基下沉,管子能偏斜,并确保密封无渗漏,从而起到自动补偿目的。
When the temperature changes in the pipe can easily among joint freedom, when foundation sink, the pipe can be skewed, and ensure no leakage seal, and so to automatically compensates for the purpose.
