External Floating Roof Tank (EFR)

API 650 App ECSExternal Floating RoofPetroleumLow Vapour EmissionOISDPontoon Type

External Floating Roof (EFR) Tanks reduce evaporation losses from high-vapour-pressure petroleum products (crude oil, gasoline, naphtha) by floating directly on the product surface, eliminating the vapour space above the liquid.

Key Features

Pontoon-type or double-deck floating roof per API 650 Appendix E
Primary seal (tube seal) + secondary seal (wiper seal) for vapour loss control
Roof drain (articulated arm type) for removing rainwater from floating roof
Roof legs, vents, inspection hatches, gauge float well on floating roof
Emergency roof drain with liquid seal to prevent vapour release

Capacity / Size Range	50,000L – 10,00,00,000L
Material of Construction	Carbon Steel (API 650)
Certifications	API 650 Appendix C / E, IS 803, OISD 118
