| specifications︰ | Gas boosters are used for high-pressure leak testing underwater Christmas trees and other subsea installations to ensure that crude or gas will not leak from the structure and risk contaminating the sea or creating a fire or explosion.
Helium gas is used at pressures up to 2000bar (30,000psi) because of its leak searching capabilities particularly in detecting porous castings. Sulphur Hexafluoride (SF6) can also be used as a leak detection gas.
