Liner pipe setting equipment and liner pipe setting method

Abstract

The invention discloses liner pipe setting equipment and belongs to the technical field of liner pipe processing. The liner pipe setting equipment comprises a heating assembly, a sealing nut, a doublethread joint, a quick joint, a connecting pipe and an air compressor, wherein the sealing nut is mounted at a first orifice of an oil pipe and the oil pipe comprises a liner pipe inside; the double thread joint and the quick joint are used for being in threaded connection to a second orifice of the oil pipe and a third orifice of the connecting pipe; a fourth orifice of the connecting pipe is hermetically connected to an exhaust hole of the air compressor; when the liner pipe is set, the heating assembly heats a surrounding space of the oil pipe within a preset time duration, and the air compressor pressurizes the inner side of the liner pipe by the exhaust hole, so that positions, including defects, between the liner pipe and the oil pipe are attached tightly. The liner pipe is set, so that wear of the liner pipe in an oil pipe using process is alleviated, and therefore, the service life of the liner pipe is prolonged effectively.

Description

technical field [0001] The present application relates to the technical field of lining pipe processing, in particular to a lining pipe shaping equipment and shaping method. Background technique [0002] Pipeline transportation has a wide range of applications in the petroleum industry. For example, during the exploitation of coalbed methane wells, the coalbed methane extracted from the gas wells can be transported through oil pipelines. [0003] In order to alleviate the wear inside the oil pipe and improve the service life of the oil pipe, in the process of exploiting coalbed methane, the oil pipe with inner lining pipe can be used to transport coalbed methane. In the process of arranging the inner liner inside the oil pipe, the inner liner is first placed inside the oil pipe, and then the inner liner is expanded so that the outer side of the inner liner fits to the inner side of the oil pipe. [0004] Affected by the corrosion and wear of corrosive gas and dust in coalbe...
