The invention discloses a heating type petroleum pipeline coupler which comprises a main pipe and pipeline interfaces, wherein the main pipe is made from a heat-conducting material; the pipeline interfaces are located at the two ends of the main pipe; a resistance wire is successively wound on the periphery of the main pipe along a radial direction thereof; an anode and a cathode of the resistance wire are respectively in electric connection with a storage battery; a protecting sleeve coats the outer side of the resistance wire on the main pipe; a protecting cover is fixedly arranged on the protecting sleeve; the storage battery is located in the protecting cover and is fixedly connected with the protecting sleeve; a power connector of the storage battery extends out of the protecting cover. According to the invention, the main pipe is warmed by controlling the power on/off of the resistance wire, so that the petroleum is heated, the consistency of the petroleum is reduced, the transportation is convenient, the operation is simple and the cost is low.
