压力管道是用压力等级区分的,是表达管道所承载的压力。 具体到是什么介质无关,只看压力测试仪表显示为准。 供参考。

“半干”?含水率应该大于50%。

是的,含水率大于50%

压力管道是有跟介质、压力、管径都有关的,介质为气体、液化气体、蒸汽或者可燃、易爆、有毒、有腐蚀性、最高工作温度高于或者等于标准沸点的液体。要同时满足所有条件的才属于压力管道,半干污泥管道应该不属于压力管道

关于定义上的问题还是看看定义是如何解释的吧,https://baike.so.com/doc/6588343-6802117.html

其范围规定为最高工作压力大于或者等于0.1MPa(表压),介质为气体、液化气体、蒸汽或者可燃、易爆、有毒、有腐蚀性、最高工作温度高于或者等于标准沸点的液体,且公称直径大于或者等于50mm的管道。公称直径小于150mm,且其最高工作压力小于1.6MPa(表压)的输送无毒、不可燃、无腐蚀性气体的管道和设备本体所属管道除外。 非特殊介质 看设计的直径和压力了
