A new type structure of wire wound super-high pressure vessel was presented.

This article describes the Shigley approximation method in the fatigue design of the super-high pressure vessel for Fuyang Project.

There is localized discontinuation in the structure of ultrahigh pressure vessel,so the stress concentration was caused.

The pre-tensile stress in wire layer of new type wire wound super high pressure vessel was analyzed,and yielding stress calculation of the wire layer was been formularized.

Ultra-high pressure vessels are widely applied in the fields and industries of chemical, petrochemical, artifical crystal, compound diamond, isometrical hydrostatics treatment, ultra-high hydrostatics extrusion, powder metallurgy, material moulding, physical geography, geologic mechanism etc.

As high-risk apparatus, ultra-high pressure vessel and pipes are widely used in ethylene polymerization, synthesis of manmade quartz and diamond, static pressure treating, ultra-high static pressure extruding, powder metallurgy, metal forming, geophysical and geomechanics research.

According to the provision of national regulation,ultra-high pressure vessel(the pressure vessel of design pressure≥100MPa) must setup the blast sheet,but all the company have not set it.

This paper presents an overview of related Japanese product standard, testing method, requirement for material, design theory and technological process for very high voltage film capacitor.
