Pressure pipeline work: what is the difference between sealing under pressure and plugging leaks under pressure?
Thread Content
In the types of work and catalog for personnel operating special equipment, what is the difference between pressure pipeline work, sealing under pressure, and plugging leaks under pressure? I would like to ask everyone for advice
Pressurized plugging is used to handle larger pipe openings, with the aim of meeting production requirements and improving process efficiency. Plugging leaks under pressure is done to address the leakage points.
Pressurized plugging stops the flow of fluid inside a pipeline, while pressurized leak sealing is used for the local repair of leaks on the outside of a pipeline. And both of these types of work fall under the category of pressure pipeline operations.
