管道除砂器在進行清砂除砂時，需開啟旁通系統(tǒng)。旁通系統(tǒng)可在工廠制作，這就是管道除砂器橇。其型號標注為在對應的管道除砂器型號前加“Q”表示。如QCS-320,即表示為公稱壓力32MPa的管道除砂器橇。

Pipeline desander in clear sand sand removal, need to open the bypass system. Bypass system can be manufactured in a factory, which is the pipeline desander skid. Said the model marked in the correspondingpipeline desander model before the "Q". Such as QCS-320, which is expressed as a nominal pressure of 32MPapipeline desander skid.
