Summary

IS 1520 covers horizontal cylindrical steel tanks for petroleum product storage at petrol pumps, fuel depots, and industrial facilities. It specifies design, fabrication (welding per IS 816), hydrostatic testing, and installation requirements for both above-ground and underground tanks.

Specification for horizontal cylindrical welded steel tanks for above-ground and underground storage of petroleum products (petrol, diesel, kerosene), covering design, fabrication, testing, and installation.

Key Values
Standard capacities1, 2.5, 5, 10, 15, 20, 25, 30, 50, 100 kL
Min shell thickness5 mm (for tanks up to 15 kL)
Test pressure (hydrostatic)0.35 kg/cm² (35 kPa)
Practical Notes
! All petroleum storage tanks must comply with Petroleum Rules and PESO (Chief Controller of Explosives) requirements.
! Underground tanks require cathodic protection or equivalent corrosion protection system.
! Tanks must be electrically earthed and bonded to prevent static discharge during filling.
! Regular inspection and calibration charts are mandatory for commercial fuel storage (petrol pumps).
! Fire protection requirements are governed by IS 2190 (petroleum storage safety) in addition to IS 1520.
