<p>The invention relates to a method of manufacturing a fluid containing vessel having a fitting. The steps include forming a liner (10), providing a preformed fitting (14) having a flange; installing an insert (24) in the fitting; and positioning the fitting (14) on a wall of the liner (10) and welding the insert to the wall. Additional steps include filament winding the liner, said filaments capturing the fitting flange against the wall; and cutting a hole through the wall of the liner inside the fitting to create a passage through the fitting and liner wall. Preferably, the fitting (14) defines a passage (18) therethrough and the insert (24) is installed in the passage (18). The insert preferably has a flange (26) that engages the fitting to retain the fitting on the liner. The passage preferably communicates with an interior of the liner through the hole. When the liner and insert are made of materials having substantially similar melting temperatures, they are preferably heated to about the same temperature. When the liner (10) and insert (24) have different melting temperatures, they are preferably heated to different temperatures. The liner 10) and insert (24) are preferably made of materials compatible for welding to each other, preferably plastic. The liner (10) may be generally cylindrical, and the fitting (14) may be located on a generally cylindrical side wall of the liner. The step of welding may include heating the insert (24) and an area of the liner (10) and pressing the insert (24) into the liner to bond therewith. <IMAGE></p> |
