Recently, a new type of multilayered vessel has been developed, whose layers are wound spirally along the whole length of cylinder continuously and automatically with high manufacturing efficiency.
The present paper introduces the burst test results for three types of the model vessels, one- directionally wound type, alternately cross- wound type and nozzle- mounted type, describing the following conclusions.
(1) Spirally wound layered vessels constructed with the appropriate spiral winding angles have the same amount of burst strength as solid-wall vessels.
(2) The evaluation curves of the burst pressure for spirally wound vessels with parameter of spiral winding angle are proposed and verified by the experiment.
(3) The nozzle- mounted type vessel which was subjected to the repeated design pressure up to 50 cycles has the burst strength in accordance with Faupel's equation for solid-wall vessel.
