Abstract
A cylindrical reinforcing collar is fitted onto a cylindrical gas discharge section of a tank body and then engaged integrally on the exterior of the tank body between the cylindrical gas discharge section and the dome section by shrink fitting. This provides, easily and inexpensively, a high-pressure tank capable of withstanding high pressures of 35 to 75 MPa while keeping its lightness in weight.
Claims4
A high-pressure tank comprising:
- a metallic tank body in which a cylindrical gas discharge section is protruded integrally from one end of a cylindrical middle section through a dome section;
- and
- a cylindrical metallic reinforcing collar fitted onto the cylindrical gas discharge section of the tank body and subsequently engaged integrally on the exterior of the tank body between the cylindrical gas discharge section and the dome section by shrink fitting,
- wherein the metallic tank body is formed by plastically deforming a hollow cylindrical blank of metal with rotation, and
- the dome section in the vicinity of the boundary of the cylindrical gas discharge section and the cylindrical gas discharge section are increased in thickness as compared with the cylindrical middle section.
