Embodiment
[0037] refer to figure 1 As shown, the long-distance pipeline connection method provided by the embodiment of the present invention mainly includes the following steps:
[0038] 101. Install an infrared emitting source and an infrared receiving source at the center of the nozzles of the two long-distance pipeline sections; the infrared emitting source and the infrared receiving source are set oppositely, specifically as image 3 shown;
[0039] 102. When the infrared receiving source accurately receives the infrared rays emitted by the infrared emitting source, fix the positions of the infrared emitting source and the infrared receiving source; that is to say, at this time, the centers of the nozzles of the two long-distance pipeline sections are on the same straight line (i.e. infrared); specifically as Figure 4 shown;
[0040] 103. Draw nozzle cutting marking lines on the peripheral pipe surfaces of the nozzle outer walls of the two long-distance pipeline sections, and t...

The invention discloses a long distance pipeline connecting head fitting method. The method comprises the following steps that an infrared emitting source and an infrared receiving source are arrangedat the centers of the pipe openings of the two long distance pipeline sections respectively; infrared rays emitted by the infrared emitting source are accurately received by the infrared receiving source, and the position where the infrared emitting source and the infrared receiving source are located is fixed; pipe opening cutting marking lines are drawn on the outer wall circumference pipe surfaces of the pipe openings of the two long distance pipeline sections respectively; blanking pipe sections are cut, the two long distance pipeline sections are carried out cut according to the cuttingmarking lines of the pipe openings, and two pipe openings of two long distance pipeline sections after cutting are used as cutting butt joint pipe openings; and the pipe openings at the two ends of the blanking pipe sections are in butt joint with the two cutting butt joint pipe openings respectively. According to the method, the blanking precision of the long distance pipeline connecting head fitting method can be effectively improved, and the construction quality is ensured.
Description
technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a head-to-mouth matching method for long-distance pipelines. Background technique [0002] Long-distance pipelines refer to pipelines that are relatively long in length and are used to transport commodities. Long-distance pipelines generally transport commodities such as oil and gas. In the construction process of the entire long-distance pipeline, the construction of the connecting head is very important. Because the connecting head is the connection of each section of pipeline, the connection construction here is related to the connection degree of the two sections of pipelines. If the connection degree is high, the connection degree of the entire long-distance pipeline will be good and the safety will be high. If the connection degree is low, It will affect the safety of the entire long-distance pipeline, and may even cause safety accidents. After long-distance...
