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. 伴热管 必须沿着待加热管路的外形轮廓、按照从最高点(自动泄放型)一直斜着向下到疏水阀的路线进行铺排。并且在铺排伴热管的过程中应当尽量避开 腔盖区域 ,同时,(线路上累计出现的) 内腔 深度不得超过3米。 2、tracers must be free of all kinks and bends flattened to less than 2/3 nominal outside diameter。 伴热管不得出现打结的情况,并且应当压平弯管,使其口径小于公称外径的三分之二。 3、the constant slope in the tracer shall be maintained as far as possible during coil wound tracing of items。 并且在用线圈缠绕正在伴热的装置的过程中,必须使伴热管保持一定的斜度。查看更多
