Abstract
The method of fabricating a tank connector assembly comprising the steps of first providing a metal spud member having an internally threaded portion and a cylindrical wall portion. Mounting an insert member of polymer material inside the cylindrical wall portion of the spud member, the insert member having a cylindrical wall portion. Positioning a bonding member between the cylindrical wall of the spud and the cylindrical wall of the insert member. Applying heat to the spud insert member and bonding member to cause the material of the bonding member to become bonded to the spud wall and the insert wall. In a preferred embodiment, the polymer material of the bonding member is maleated olefin. The metal spud member is welded in an opening in the wall of a steel tank. A polymer material is introduced into the interior of the steel tank and the tank is then subjected to a rotational casting movement in the presence of heat to cause the polymer material in the tank to be uniformly distributed over the internal surface of the tank. The heat applied during the rotational casting step serves to cause the bonding member to become bonded to the spud and insert member.
