A tank closure assembly adapted to releasably couple tank sections formed by transversely splitting an integral bag-molded fiber-reinforced tank. The assembly includes external circumferential flanges secured to the tank sections adjacent their severed faces and in opposed relation to each other. An O-ring seal, disposed externally of the tank sections and between the flanges, is compressed into sealing engagement with surrounding surfaces, by tightening of a circumferential band encircling the flanges, to seal the tank sections at their plane of separation. A method of machining a tank to simultaneously form the split sections and suitable flange receiving grooves thereon is disclosed, as well as a method of pressure-testing the machined tank sections prior to assembly of the flanges and O-ring seal.

Tank closure assembly

A pressurizing tank for a liquid dispensing system is disclosed. The system includes a pressure withstanding vessel having openings at both ends with a strainer fitting fixed in one of the openings. A flexible, inflatable, gas-tight bag is provided in the vessel and has an inflating valve at one end thereof which is fixed in the other opening in the vessel. The other end of the bag is fixed to the strainer fitting.
