ImportantInstallationGeneral InformationOrdering InformationIf using a carbon or stainless steel tank with AFFF type foam concentrates, Chemguard does not recommend lining the inside tank shell. The rea is that the tank and the liner have different coefficient expansion ratios during various ambient temperature cycles. Over time, pinholes may occur in the lining. AFFFs having a very good wetting ability will penetrate the pinholes and get in between the lining and the tank shell. Eventually portions of the lining may flake off and travel into the foam concentrate system, sSee more on chemguardLPG storage tank design calculations What Is PipingStorage capacity-The volume from the tank bottom to the maximum design level.
