The electromagnetic heating unit for oilfield pipelines produced by Puneng has been very mature in energy-saving heating applications. The oil pump unit is the "heart" of the entire oil transportation production and an important part for the speed of crude oil transmission. According to the heating length of the ground oil pipeline, the electromagnetic heating equipment we produce can effectively control the stability of the pipeline heating temperature and ensure the transmission effect. Currently, it is used in heating fields such as pharmaceutical chemicals, plastic machinery, oilfield pipelines, and metallurgy.
In winter, due to the low outdoor temperature, the high wax content in the oil pipeline makes the pipe fittings prone to freezing and blockage. The traditional method is to use fire, but using open flames violates the safety regulations prohibiting open flames in oil production areas, and oilfield solid control equipment is prone to safety accidents. Heating with electric heating plates destroys the original insulation layer, and has large heat loss, slow speed, long time, and high power consumption. The high-frequency heating of Puneng's energy-saving electromagnetic heater can penetrate insulation materials such as asbestos and fiber cloth, and quickly heat metal pipe fittings by induction to achieve unblocking.
Features of Puneng's dedicated electromagnetic heater for oilfield pipelines
1) High thermal efficiency: high energy conversion efficiency, the energy-saving electromagnetic heater does not need to preheat the pipeline.
2) High safety: no open flame, no thermal radiation, controllable temperature, with explosion-proof, dust-proof, rain-proof, and lightning-proof design.
3) Easy operation: wrap the electromagnetic coil around the pipeline, install the temperature control probe, adjust the temperature control system, and start the machine to automatically control heating and maintain constant temperature.
4) Digital control with stepless power adjustment. Advanced protection functions such as overvoltage, overcurrent, overtemperature, water shortage, and phase loss.
Summary: Puneng's electromagnetic heating converts 50Hz AC into 20KHZ-30KHZ high-frequency AC current through a high-frequency control generator, which is then converted into a high-frequency alternating magnetic field by the electromagnetic heating inductor. The magnetic field lines of this high-frequency alternating magnetic field act on the metal pipeline to generate eddy currents, thereby rapidly heating the metal pipeline. Electromagnetic heating units of different power specifications can be customized according to the needs of oil and gas field customers.
