The extraction piping for liquefied hydrocarbon equipment should be equipped with a shut-off valve near the base of the equipment. When the distance between a liquefied hydrocarbon unit with a volume of over 50 m3 and its extraction pump is less than 15 m, such a shut-off valve shall be a remotely operated valve with a manual function; the distance between the local operation button of the remotely operated valve and the extraction pump shall not be less than 15 m.
Correct. This requirement is derived from 7.2.15 of GB 50160-2008 Code for Fire Protection Design of Petrochemical Enterprises: Isolation valves shall be installed on the extraction pipes of liquefied hydrocarbon equipment near the base of the equipment. When the distance between a liquefied hydrocarbon unit with a volume of over 50 m3 and its extraction pump is less than 15 m, such a shut-off valve shall be a remotely operated valve with a manual function; the distance between the local operation button of the remotely operated valve and the extraction pump shall not be less than 15 m.
