Надувная заглушка трубопровода против механической заглушки: Какая из них более экономична для временной остановки трубопровода?
For a temporary line stop, an inflatable pipeline plug is generally more cost-effective than a mechanical plug for the majority of applications involving low-to-medium pressures, large diameters, or irregular pipe interiors, due to lower equipment costs, faster installation, and reduced labor requirements. However, for long-term, high-pressure isolations in pristine pipe, a mechanical plug may offer
