METHOD OF MANUFACTURING A PRESSURE VESSEL WITH AN IMPROVED SIDEWALL STRUCTURE ABSTRACT OF THE DISCLOSURE A method is provided for constructing a thin- wall pressure vessel having a thermoplastic inner liner, a filament wound outer shell and at least one localized area of increased thickness in its sidewall. The method includes providing an insert formed from thermoplastic material or other suitable material which is bondable with the material of the inner liner. The manufacturer uses this insert to form a localized area of increased thickness in the sidewall of the pressure vessel. First, the manufacturer blow molds or otherwise forms a thermoplastic inner liner and bonds the insert to the inner liner. The manufacturer then provides a means for locating or finding the port of the insert and constructs the outer shell with glass filaments impregnated with a resinous material or other suitable material. Then, after locating the insert, the maker forms an opening which extends through the entire sidewall of the pressure vessel.
