Modular tanks are pre-engineered, sectional storage systems designed for efficient containment of liquids such as water, wastewater, chemicals, and fuel. These tanks are constructed from prefabricated panels—typically made of steel, stainless steel, aluminum, or reinforced composite materials—that are bolted or welded together on-site, allowing for flexible configurations and scalable capacity.
At Siegen Philippines, our modular tanks are engineered to meet stringent industry requirements, offering:
• Rapid Deployment – Prefabricated components reduce installation time and site disruption.
• Custom Sizing – Tanks can be configured in various dimensions to match specific volume requirements, ranging from a few cubic meters to several million liters.
• Material Options – Available in carbon steel, stainless steel (304/316), or coated with epoxy, polyurethane, or glass-fused-to-steel finishes for enhanced chemical and corrosion resistance.
• Structural Integrity – Designed to withstand internal pressure loads, external soil pressure, seismic activity, and environmental stressors.
• Compliance-Ready – Manufactured in accordance with international standards such as AWWA D103, API 650, or ISO 28765, depending on application.
• Ease of Maintenance – Modular access panels and integrated manways allow for internal inspection, cleaning, and maintenance.
