LPG Storage Tanks
MARU manufactures and supplies a complete range of LPG storage tanks for domestic, commercial, and industrial use.
All tanks are designed and tested to international pressure vessel standards, ensuring long service life, maximum safety, and dependable performance.
Aboveground LPG Storage Tanks
Aboveground LPG tanks are available in a wide range of capacities — from 500 to 300,000 litres — for both domestic and industrial installations.
Manufactured from fine-grain pressure vessel steels such as P355 series according to EN 10028-3, each tank is fabricated under certified welding procedures (EN ISO 9606-1)
and inspected by accredited third-party organizations.
Typical design conditions include a working pressure of 17–17.5 bar, a test pressure up to 26.5 bar,
and an operating temperature range from -20°C to +50°C. The tank shells and dished ends are stress-relieved and shot-blasted to SA 2.5 grade before coating.
Final protective coating is applied with high-performance epoxy or polyurethane paint for long-term corrosion resistance.
Underground LPG Storage Tanks
Underground tanks are ideal for sites with limited space or where aesthetic and environmental concerns require concealed installations.
Capacities range from 1,000 to 50,000 litres, with options for horizontal or vertical configurations.
The tanks are externally coated with dielectric polyurethane or epoxy systems to protect against soil corrosion.
For long-term reliability, all underground models can be equipped with cathodic protection systems including anode kits, test points, and monitoring terminals.
Each tank is manufactured and tested in accordance with EN 13445, EN 12542, and PED 2014/68/EU,
with optional designs according to ASME Section VIII Div.1 or AD2000 standards.
High-Capacity Industrial Tanks
MARU high-capacity LPG tanks are engineered for bulk storage and terminal operations up to 300,000 litres.
They are supplied with a full set of accessories including safety relief valves, pressure gauges, magnetic level indicators, manholes,
fill/discharge valves, and excess flow valves.
Each vessel is designed for efficient loading and unloading operations, and can be integrated into skid-mounted or modular storage systems.
All tanks are subjected to radiographic, ultrasonic, and hydrostatic tests to ensure total structural integrity before delivery.
