Abstract: Oil pump room, the hub of tank farm, has its functions done by the oil pumps and pipe range in it. How to arrange the pipe range for safe and reasonable pump operation has been the major concern ever since. Horinzontal pipe range, the conventional arrangement in oil pump room, has such disadvantages as difficult valve manipulation and hard draining of the residual oil. Rearranging to vertical direction has been attempted since the early 70's. After over 20 years of application, it is proved that vertical arrangement of pipe range has the following three advantages: ①reasonable in arrangement, easy to operate; ② small land occupation and low investment; ③pleasent to eyes and easy to automize.
