摘要： 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.

摘要： A tank closure assembly adapted to releasably couple tank sections formed by transversely splitting an integral bag-molded fiber-reinforced tank. According to one aspect of the invention, 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. According to another aspect of the invention, the assembly includes a unitary clamping band having hooked ends which engage grooves adjacent the severed faces of the tank sections and the clamping band retains a pair of O-rings which seal the tank at their plane of separation. A method of machining a tank to simultaneously form the split sections and suitable flanges 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.
