Title:
METHOD OF SEALING LEAKAGE
Document Type and Number:
Japanese Patent JPS58134296
Kind Code:
A
Abstract:
The flow of liquid escaping from a leak in a vessel, e.g., a pipeline, is reduced or eliminated by introducing particles into the liquid. The particles are dispersed in a slug of material of higherviscosity than the liquid in the vessel and the size of at least some of the particles is greater than that of the hole. The position of introduction of the slug is such that the slug containing the particles is carried by the liquid to the hole. The particles ar non-deformable so that they lodge in the hole without extruding through at elevated pressure and thereby seal the hole.
