Pipeline Equipment
SDQ Plugging Device Series
Equipment Description:
The plugging device is mainly used to send the plug handle of the plugging pipe into the predetermined position of the pipe fitting after the pipeline plugging operation is completed, so that the sealing element on the plug handle fits with the inner diameter of the pipe fitting to achieve the sealing purpose, and cut off the medium in the pipeline, so that the construction equipment connected by the plugging pipe fitting can be removed.
The equipment is suitable for the construction of flammable, explosive, toxic and harmful crude oil, chemical industry, liquefied petroleum gas, coal gas, natural gas and other liquid and gas transmission pipelines and urban water supply and heating pipelines under pressure.
Device characteristics:
- Stopper piston rod telescopic stroke display
- The connection type of base and plug hook is flange connection
- Continuous sealing
