ABSTRACT:
The attachment of a tubular pipe connection means to the wall of a storage tank of similar structure in which an end portion of the pipe connection means attachable to the wall is provided with an inwardly inclined conical collar having at its free end portion an outwardly directed conical flange. A bar with a conically-shaped free end portion being insertable into the pipe connection means so that the free end portion thereof contacts the inside of the collar with a conical hole piercing member being attached to the free end portion of the bar in contact with the inside of the flange of the pipe connection means. The arrangement is such that when the hole piercing member together with the pipe connection means are moved axially through the wall of the tank, the conical collar and flange, via the conically shaped free end portion of the bar, are pressed outwardly and caused to bend and grip the edge of the hole formed in the wall by the piercing member.
