Description

Technical Field

[0001] The utility model relates to the technical field of lined polyfluoro tubes, in particular to an antistatic lined polyfluoro tube for oil and gas transportation. Background Art

[0002] Lined PTFE pipe is a special pipe material, which lines the inside of metal or other base pipes with polytetrafluoroethylene material. This pipe combines the excellent chemical stability of PTFE and the structural strength of metal pipes, so it has extremely strong corrosion resistance and can resist the erosion of almost all strong acids, strong alkalis and various organic solvents. When the existing PTFE pipe is used, it cannot filter the oil and gas transported inside, affecting the purity of the oil and gas. Moreover, when used for a long time, the solid impurities mixed in the oil and gas will cause wear and corrosion to the inner wall of the pipe, shortening the service life of the pipe.

[0003] According to the description in an antistatic polytetrafluoroethylene tube for oil and gas transportation published on the patent website (authorization announcement number: CN215522295 U), the antistatic polytetrafluoroethylene tube for oil and gas transportation includes "insulation tube, transportation pipeline, sealing tube" etc. to assist transportation work.

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] The antistatic polytetrafluoroethylene tube used for oil and gas transportation utilizes an insulation tube, a transportation pipeline, a sealing tube, etc. to perform auxiliary transportation work. When the pipeline is in use, it is unable to filter the oil and gas being transported in the pipeline, thereby affecting the purity of the transported oil and gas. When the transportation work is performed for a long time, the solid impurities mixed in the oil and gas will cause wear to the inner wall of the pipeline, affecting the service life of the pipeline. Therefore, it is necessary to improve the ethylene tube. Utility Model Content
