Industrial Hydrostatic-Grade LPG Tank Mould For High-Pressure Gas Containment Shells

This advanced LPG cylinder mould system is designed to facilitate the complex plastic deformation required for two-piece and three-piece pressure vessels. Our engineering philosophy centers on the "Material Memory" of the steel, ensuring that the dome and body sections maintain perfect volumetric symmetry. By controlling the grain-flow orientation during the forming process, we produce gas cylinder halves that exhibit superior resistance to internal circumferential stress, meeting the rigorous safety mandates of global energy distributors.

Volumetric & Structural Engineering

The safety of an LPG vessel is dictated by its weakest point. Our mould design eliminates localized structural thinning through:

Symmetric Flow Dynamics: We utilize high-coefficient friction management on the blank holder to ensure that the steel sheet draws evenly into the cavity, preventing off-center mass distribution.

Knuckle Radius Reinforcement: The tooling geometry is optimized to create a gradual transition at the knuckle, which redistributes pressure loads more effectively than standard parabolic designs.

Elastic-Modulus Compensation: The mold surface incorporates micro-adjustments to account for the specific springback characteristics of high-strength vessel steels (e.g., HP295 or SG295).

Sustainability & Production Yield

Our LPG cylinder mould technology is built for the "Green Manufacturing" era. By achieving an ultra-smooth internal finish, we reduce the surface tension of the metal, which minimizes the need for aggressive post-draw chemical cleaning. Furthermore, our "Quick-Bleed" air venting system prevents trapped pockets from creating surface micro-voids, ensuring a 99.8% first-pass yield. This focus on process efficiency directly translates to lower energy consumption and reduced carbon footprints for large-scale gas tank production facilities.
