Vacuum-insulated transport pipe device and pipeline transport system

A vacuum-insulated transport pipe device, including an inner pipe, an outer pipe, and an electric heating structure, wherein the inner pipe is used for transporting flowable substances and the outer pipe forms a chamber;

• the inner pipe is disposed within the chamber, two closure structures respectively seal both ends of the chamber along the axis of the outer pipe, and the inner pipe passes through each closure structure and extends to the outside of the outer pipe;
• a one-way valve is installed on the outer pipe and communicates with the chamber;
• the electric heating structure is disposed within the chamber and circumferentially surrounds the inner pipe, and a space is formed between the electric heating structure and a wall of the outer pipe on the side facing the chamber;
• the outer pipe forms an installation hole connecting the chamber and the outer periphery of the outer pipe, an electrical connection port is installed in the installation hole and forms an airtight bond with the outer pipe;
• the electric heating structure is electrically connected to the electrical connection port;
• a temperature sensor and a pressure sensor are respectively configured in the chamber, and the temperature sensor and the pressure sensor are respectively electrically connected to the electrical connection port, wherein the temperature sensor is connected to the inner pipe for sensing the temperature of the inner pipe, and the pressure sensor is used for sensing the air pressure in the chamber.
