LNG = LIQUIFIED NATURAL GAS
Natural gas mainly in the form of Methane, after being extracted from gas fields, will be processed in a gas processing plant where its impurities such as CO2, Water & Sulfur will be removed. Now it is time to transport the gas to the end users for distribution. Eventually, either a gas pipeline will be used or Natural gas gets liquefied at cryogenic temperature of -265°F (-160°C). When natural gas is turned into LNG, its volume shrinks by factor of 600. This reduction in volume enables the gas to be transported economically over long distances.

FULL CONTAINMENT HAS BECOME THE MOST COMMONLY BUILT LNG TANK TYPE DUE TO ITS SAFETY AND ECONOMIC VALUE
The inner tank is made of 9% Nickel steel and the outer tank is made of prestressed concrete (PC). Between the inner and outer tank there is a vapor barrier made of thin carbon steel plate and many different types of insulations.
VERTICAL JOINTS
9% Nickel vertical joints are welded in vertical up. For this reason either SMAW electrode is applied manually or FCW for semi-automatically and fully automatic welding.
FOR VERTICAL JOINTS SMAW AND FCAW ARE THE DOMINANT PROCESSES
For manual process Nyloid 2 has been used for decades in many projects worldwide as the electrode of choice and Supercore 625P FCW is proven to offer the best combination of excellent weldability and mechanical properties.
