LNG Valve Testing Project
Several butterfly valves were tested at cryogenic conditions for LNG application witnessed by Bureau Veritas Marine.
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport.
It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure).
It is odourless, colourless, non-toxic and non-corrosive.
Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia.
To enhance and maintain our high standards of valve design and production testing, we operate with stringent cryogenic testing programmes in our test facility.
Valves can be tested at any controlled temperature down to -196°C (boiling-point of liquid nitrogen). The parameters we monitor include the measurement of leakage for seats and body, operating torques, and cycling under typical low temperature or cryogenic conditions.
Tests are carried out in accordance with recognized international standards or can be designed to our customer’s own specifications to ensure application suitability.
