According to ISO4437:1988(E)A1: "If the pipe is in contact with liquid hydrocarbons (condensate, odorant
or aromatic hydrocarbon) during the entire use of the pipe, it is recommended to use SDR11 (S5) series
pipes for the 50-year life. my country's artificial coal gas and liquefied petroleum gas generally contain liquid
hydrocarbons, so it is stipulated that SDR11 is suitable for transporting natural gas, artificial coal gas and
liquefied petroleum gas.
