Polyurethane pipelineSolidDecoking pig from Yantai Zhengyuan Polyurethane Co.,Ltd.Is a key tool for mechanical decoking to fired heater tubes and pipelines.They areMade of optimum quality PU andwithsome designs,colors and sizes available for option.Also can be customized according to buyers' special requirements.They are very effective and efficient to clean the inner surface of pipes of different materials.

Polyurethane pipelineSolidDecoking pig Will be used in the decoking system as following:

the entrance and exit of the water pumpin the decoking systemIs respectively ConnectEd with the entrance and exit of the pipe to be cleaned toForm a closed circuit. A launcher and a receiver are installed at the entrance and exit of thepipes respectively and a PU pipelineSolidDecoking pig from Yantai Zhengyuan Polyurethane Co.,Ltd.Placed in the launcheris pushed into thepipe by the pressure water generated by the water pump. the engine continues to work so that tHe pressure waterkeep pushing thepOlyurethane pipelineSolidDecoking pig from theEntrance through thepipE into the receiver finally at theexiT. Then Operate the change-over switch toChange the water flow direction so to push theUrethane pipelineSolidDecoking pig in the receiver back into thePipe again byContinuousPressure waterandFinally thepOlyurethane pipelineSolidDecoking pig back into the launcherfor completing a cleaning process.
