The invention discloses a diaphragm type pressure filter pressurization pipe heating power pressure supplementing pipe. In use, a pipe body is connected into a pressurization pipe, a circulation coveris connected to the outer wall of the pipe body in a sleeving manner, a circulation upper cavity, a circulation middle cavity and a circulation lower cavity are formed in the circulation cover, an oil inlet is further formed in the circulation cover, and high-temperature heating oil enters the circulation cavities in the circulation cover from the oil inlet; and an oil collecting cylinder is further arranged in the circulation cover, an oil outlet pipe is arranged on the oil collecting cylinder, and a heat insulation plate is further arranged on the outer wall of the oil collecting cylinder.The diaphragm type pressure filter pressurization pipe heating power pressure supplementing pipe is connected into the pressurization pipe when used, and the high-temperature heating oil is led in from the exterior so that high-pressure fluid in the pipe can be subject to quick heat transferring; and by means of the circulation cavities in the circulation cover, the time of heat transferring between the high-temperature heating oil and the pipe can be prolonged, and heating power pressurization of the heating oil on the high-pressure fluid in the pipe is further improved. By means of the heating power pressure supplementing pipe, the internal pressure of the high-pressure fluid can be effectively improved, noise is low, and the pipe cannot be damaged.
