A kind of oil pipe device and its processing method

Abstract

The invention discloses a machining method of an oil way pipe device and belongs to the technical field of fluid devices. According to the machining method of the oil way pipe device, an oil way pipeis included, and the oil way pipe device is characterized in that the oil way pipe comprises a first-order oil way pipe body, a second-order oil way pipe body, a third-order oil way pipe body, a fourth-order oil way pipe body, a fifth-order oil way pipe body, a sixth-order oil way pipe body and a seventh-order oil way pipe body; and the first-order oil way pipe body, the second-order oil way pipebody, the third-order oil way pipe body, the fourth-order oil way pipe body, the fifth-order oil way pipe body, the sixth-order oil way pipe body and the seventh-order oil way pipe body are each provided with a groove. According to the machining method of the oil way pipe device, flaw detection of a blank pipe is performed on the pipeline in advance by using a thermotechnical transverse wave emitting method, so that the later period quality cost can be effectively lowered, the pipeline is subjected to segmented machining, and the needed shape inner diameter of the oil way pipeline is guaranteed; then sealing rings are additionally arranged by forming the grooves, and the sealing performance of fluid in the pipeline is guaranteed; and finally, an advanced submerged-arc welding process is used, various orders of the oil way pipe are welded, water pressure testing is performed, and the adhering performance and the high pressure resisting capacity of the pipeline are further guaranteed.

Description

technical field [0001] The invention relates to the technical field of fluid equipment, in particular to an oil pipe device and a processing method thereof. Background technique [0002] Pipeline refers to a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles; usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it is discharged from the pipeline. The flow from the high pressure to the low pressure can also be carried by the pressure or gravity of the fluid itself; the pipeline is widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various in an industrial plant. [0003] With the development of science and technology, there are various types of pipelines. In some special fields, such as flammable and explosive oil products, some special pipelines are required to fo...
