Beschreibung
Zusammenfassung:	The present invention relates to a new improved device for sealing damaged tubular members by using a readily removable cylindrically configurated member which is disposed securely within open end sections of the tubular member. The present device includes a projecting end portion which is insertable into the damaged tubular member and which is connected integrally to a sleeve portion configurated externally with tube engaging projections and internally with a retraction device for removing the device when tube repairs are effected. The device of the present invention thus provides a useful means for sealing damaged tubular members of a multi-tubular unit without requiring complete shut-down each time an individual tubular member becomes damaged or inoperable.
