NEWLY INSTALLED BURIED TANK WITH DOUBLE SHELL STRUCTURE AND MCH STATION EQUIPPED WITH DOUBLE PIPING STRUCTURE

摘要

To provide MCH station equipped with a double piping structure that can easily detect corrosion and pitting corrosion of the pipping that occurs in the tank by using a newly installed double shell buried tank equipped with a MCH (methylcyclohexane) detector inside, in addition, that can detect a defect of piping by providing a detector capable of detecting MCH leakage depending on the double piping structure where double piping is installed.SOLUTION: A newly installed buried tank having a double shell structure has an inner shell, an outer shell, a liquid detection line disposed between the inner shell and the outer shell, and a liquid detector connected to the liquid detection line. The liquid leaking from the inner shell is detected by the detection line, and the liquid detection information detected by the liquid detector is reported to the outside, and the pipping leading to the newly installed buried tank has a double pipping structure and also a detector for detecting leakage of MCH.SELECTED DRAWING: Figure 1
