ABSTRACT:
A sealing assembly for vessels such as tanks, pipe lines etc. for preventing leakage of fluid from such vessels. The sealing assembly incorporates an inner stop member which is collapsible for passage through a hole in the wall structure of the vessel and is expandable to engage the inner surface of the vessel. A closing and sealing material is applied to the external surface of the vessel in an uncured form and extends at least partially through the hole through which the stop member passes. A retainer plate is positioned on the outer surface of the closing material and is drawn into tight retaining engagement with the closing material by means of a forcing element in the form of a screw or screws which extend through the retainer element and are received in threaded engagement with the stop element. The closing material is in the form of a polymer which is applied in the uncured state and forms a bond with the outer surface of the vessel. The retainer plate is forced into assembly with the polymer closing material by the screws to positively secure it in place.
