Medium- and high-frequency electromagnetic heating clasping device for heating and unfreezing pipeline

Abstract

The invention provides a medium- and high-frequency electromagnetic heating clasping device for heating and unfreezing a pipeline, and aims at solving the problems that a wellhead is roasted and heated with open fire during replacing a packing, which is small in working efficiency and easy to cause potential risk, and the mode of coiling the pipeline with a coil to heat at the field is limited and cleaning cannot be performed. The device comprises a clasping body; the clasping body comprises two symmetric semicircular stainless steel bodies and is connected through a hinge; a heat insulating plate is arranged on the clasping body, and a high frequency coil is paved on the heat insulating plate; a temperature sensor is mounted on the clasping body; when in use, the device is clasped into an oil production packing in an oilfield or water and steam pipeline and other heated objects, then a power supply is connected, the temperature and parameters are set as requirement, and finally petroleum or ice in the heated object can be unfrozen after the set temperature is reached, and thus the purpose of normal construction can be reached; the device has the characteristics of being convenient to mount and dismount, high in working efficiency, and easy to be cleaned.

Description

technical field [0001] The invention relates to a medium and high-frequency electromagnetic heating buckle device for heating and thawing pipelines. The heating device is suitable for use on oil production wellheads, oil production pipelines, steam injection or water injection pipelines in oil fields, and belongs to the manufacture and application of electric and electronic heating equipment. technology field. Background technique [0002] The oil field Christmas tree is the necessary channel for oil, natural gas and other gases to be extracted from the ground to the surface, and the packing box is an important process for controlling oil and gas blowout and leakage. When the packing inside the packing box is worn out and overturned, the packing box is not tightly sealed, and oil and gas will leak from the upper end of the packing box, causing pollution or even a blowout accident. Therefore, it is important to replace the packing in time to avoid oil and gas leakage. Import...
