Simple Definition

A 90 KL double wall HSD tank is a 90000 litre capacity diesel storage tank with dual layer construction where the outer wall acts as a protective barrier to prevent leakage and ensure safe fuel storage

Superior Leak Detection and Safety

Designed with double walls and a dedicated interstice monitorable space, the tank incorporates a leak detector port, ensuring rapid identification of leaks. Hydrostatic and pneumatic testing, along with strict compliance to PESO and IS standards, ensure enhanced operational safety even in the most demanding environments.


Durable Construction and Corrosion Protection

The tank is fabricated and welded from IS 2062 / ASTM A36 mild steel, with both internal and external surfaces coated in epoxy paint. This comprehensive coating extends the service life of the tank, minimizing maintenance and protecting against rust and chemical degradation regardless of installation location.


Customizable Capacities and Fittings

Ranging from 5,000 to 100,000 liters, the storage tank is tailored to fit specific project needs. It features a 500 mm manhole with optional diameters, API-standard nozzle fittings, and a selection of accessories such as level indicators, ladders, and platforms to support operational convenience.
