Abstract

The invention relates to an electromagnetic sensing type pipe three-layer poly ethylene (3PE) anticorrosive fast stripping device which is composed of an electromagnetic heating control system and a heating coil. The output end of the electromagnetic heating control system is connected to the heating coil on a pipeline in a winding mode. The output ends of a high-frequency current detector, an input current detector, an insulated gate bipolar translator (IGBT) temperature detector, a negative load temperature detector and a grid voltage detector of the electromagnetic heating control system are connected with the input end of a single-chip microcomputer control system. The output end of the single-chip microcomputer control system is connected with a power modulator, double PWM generators, a frequency tracking phase-lock control circuit and an isolation driver serially in sequence. The output end of a power source is connected with a large-power rectifying circuit, the output ends of the large-power rectifying circuit and the isolation driver are connected with an IGBT full-bridge inverter circuit, and the output end of the IGBT full-bridge inverter circuit is connected with the heating coil. The heating coil is a quick-assembly type flame-retardant heating strip. The electromagnetic sensing type pipe 3PE anticorrosive fast stripping device does not damage steel tube bodies or influence welding strength of steel tubes, is convenient to operate and saves labor.

Description

technical field [0001] The invention is an electromagnetic induction type pipeline 3PE anti-corrosion quick stripping device. It relates to the technical field of piping systems. Background technique [0002] Because 3PE anti-corrosion has strong corrosion resistance, this anti-corrosion material has the ability to resist strong acid and alkali. It also has good corrosion resistance and impact resistance under low temperature conditions, low water absorption of PE, high epoxy strength, low water absorption of PE and good flexibility of hot melt adhesive, etc., and has high anti-corrosion reliability, because 3PE This characteristic of the anti-corrosion layer has brought many times of invariance to the removal of sudden emergency repairs or planned pipe changes, fires, etc., so the following equipment was invented. [0003] 1. The West-East Gas Pipeline Company applied for a set of patents in 2010 for a "crawler-type large-diameter pipeline external anti-corrosion layer st...
