Circular Post-Tensioning Applications
Post-tensioning in cylindrical structures applies circumferential prestress to tank and silo walls, enhancing resistance to internal pressure, liquid loads and external effects. This method is widely used in cylindrical concrete structures including LNG storage tanks, silos, wastewater treatment plants and digesters.
ASZ GRUP manages the full process from design to installation with an engineering team specialised in circular post-tensioning for cylindrical structures.
LNG Storage Tanks
LNG tanks are high-security structures designed to store liquefied natural gas safely at extremely low temperatures (-162 °C). Circular post-tensioning is critical in these tanks to ensure containment watertightness and structural integrity of the concrete wall.
- Primary and secondary containment — Eliminates leakage risk with a double-barrier safety system.
- Cryogenic durability — Material and strand selection suited to extremely low temperatures.
- High internal pressure resistance — Circumferential post-tensioning balances pressure in the wall section.
Silo Structures
Circular post-tensioning resists lateral pressure from stored materials in silos for grain, cement, clinker and other industrial products, achieving high capacity with thinner wall sections.
- Reduced wall thickness and material savings
- Crack control and long-term structural performance
- Flexible design options for various diameters and heights
Wastewater Treatment Plants
Circular post-tensioning in cylindrical concrete tanks and basins at wastewater treatment plants improves structural resistance and watertightness against internal pressure and liquid loads. We deliver durable, reliable solutions for clarifiers, equalisation tanks and similar cylindrical structures.
