我公司4M8(3)和4M20压缩机的一段至六段出口管道均为淋洒式冷排冷却,冷排进口温度在80～150℃,出口温度在30～50℃,而压力最高达27MPa。由于各段压力管道进出凉水池部位未完全受到水淋洒,而是部分水滴飞溅到管道上,造成管道长年处于干湿交替状态,腐蚀严重,表面形成许多凹坑,严重影响压力管道的安全使用。 Our 4M8 (3) and 4M20 compressors section I to VI of the export pipeline are cold shower cooling, cold row inlet temperature of 80 ~ 150 ℃, the outlet temperature at 30 ~ 50 ℃, while the pressure up to 27MPa. As each section of the pressure pipe into and out of the cold water pool is not part of the water shower, but part of the splash of water droplets on the pipeline, resulting in the pipeline for many years in an alternating wet and dry conditions, serious corrosion, the surface of many pits, seriously affecting the safety of the pressure pipe use.
