Technology of assembly-welding of the body of the flare separator FS-1000-1-T-I

Flare separators are designed to separate liquid from the gas discharged to the flare. Separators are part of the flare system for the construction of gas and gas condensate fields. Separators are designed for operation in slightly corrosive environments (with H2S content up to 0.001% mole) and corrosive environments (with H2S content up to 70% mole)
