The Study of Kogas Membrane Performance Test for LNG Storage Tank

Kogas 멤브레인 성능평가에 관한 연구

LNG demand has been rapidly increasing in Korea for a variety of reaso including stable supply, non- polluting, and high combustion efficiency characteris As a result the construction and expansion of LNG storage facilities have b continuing at a vigorous pace. One of the most important structural core elemen the LNG storage tank is the membrane, consisting of stainless steel. The memb to be applied inside of LNG storage tank is provided with corrugations to abs thermal contraction and expansion caused by LNG temperature. From the viewp of strength design, however. it is essential to confirm that the membrane undergo a stable deformation and has a sufficient fatigue strength Experim studies are presented to investigate the deformation and strength of the memb which is designed by Kogas. All experiments are conducted on the basis of RP and we found the results is fully satisfied with the RPIS.
