A method and apparatus for forming a tubular joint. The tubular joint is between a fitting (10) and a tubular conduit (32), which have mating surfaces with a small space therebetween. One or the other, or both, of the fitting (10) and the tubular conduit (32) have a groove (36) formed on its respective mating surface. The groove can be continous or a segment. One or the other of the fitting (10) or the tubular conduit (32) has a plurality of holes (26) formed therein. At least some of the holes are for injection of a tubular joint adhesive into the tubular joint, and the rest of the holes are for the passage of the tubular joint adhesive out of the small space therebetween. Injection of the adhesive can be facilitated by an apparatus for connecting the mating surface of the fitting to the mating surface of the tubular pipe by means of the tubular joint adhesive. The apparatus uses a piston (58) and cylinder assembly (46) to compressive inject the adhesive into at least one of the holes until the adhesive passes through the space between the fitting and the tubular conduit and out of another of the holes. The apparatus can be set to deliver a calibrated amount of the adhesive, so that sufficient adhesive can be delivered to the joint without being wasteful of the adhesive. |
