Engineering Architecture & Construction
1. Seamless Continuous Extrusion Spiral Shell
Continuous thermoplastic strip extrusion winding eliminates axial weld seams completely, removing the primary point of failure found in sheet-welded tanks.
2. Graduated Wall Thickness Optimization
Wall thickness is dynamically increased from top to bottom according to hydrostatic pressure gradients, saving weight while providing maximum safety factors.
