Beschreibung
Zusammenfassung:	The invention discloses an inbound and outbound pipeline arrangement system of a pig launcher, and belongs to the technical field of long-distance pipelines of the ground engineering of oil and gas fields. According to the inbound and outbound pipeline arrangement system of the pig launcher, the pig launcher is fixed on the ground, and a cylinder wall on one side of the pig launcher is connected with an oil inlet pipeline, so that oil or natural gas can flow into the pig launcher conveniently, an outlet end of the pig launcher, a ground-out elbow, a ground-in elbow and each curvature elbow aresequentially connected through the oil outlet pipeline to ensure that the ground-in elbow and each curvature elbow are buried underground, and the curvature of each curvature elbow is larger than orequal to three times of the pipe diameter of the oil outlet pipeline, so that the system can absorb the thermal expansion deformation of the underground oil outlet pipeline by utilizing the elastic deformation of the curvature
