    摘要: A system for plugging holes in vessels which comprises the combination of a storage and delivery system for a foam-forming material, and a hole-plugging assembly. The hole-plugging assembly includes a flexible nonelastic bag member which is inserted in a folded position into the hole to be plugged and properly positioned with an associated locating means. Thereafter, a unitary foamable material is injected into the bag member to expand it and seal the hole. The locating means further assists in maintaining the inflated bag member in proper orientation and sealing engagement while the foam is curing.
