保温伴热要求？ 1、tracers shall follow the contours of the piping to be heated from the highest point sloping (self-draining pattern )towards the steam trap. pockets should be avoided, and the maximum accumulated pocket depth is 3m. 应根据加热管线轮廓，从倾坡最高点（自疏水）至疏水阀敷设伴热管。应避免液袋（冷凝液），液袋（冷凝液）累积最厚不超过3m（对m单位不能确定，也不能理解，往高人指点）。 2、tracers must be free of all kinks and bends flattened to less than 2/3 nominal outside diameter。 伴热管应避免扭曲和弯曲；矫直差应小于外径的2/3。 3、the constant slope in the tracer shall be maintained as far as possible during coil wound tracing of items。 3、伴热管上的连续倾坡应尽量远离盘管伴热。查看更多
