Device and method for testing environmental adaptability of nonmetal pipe for oil gathering and transportation

The invention discloses an environmental adaptability test device and method for a non-metal pipe for oil gathering and transportation, and the device comprises a plurality of first pup joints which are sequentially connected from upstream to downstream in an end-to-end manner, the tail end of the last first pup joint at the downstream end is connected with a second pup joint, and the front end of the first first pup joint at the upstream is connected with an inlet pipeline. The inlet pipeline is sequentially connected with a first emptying valve, a first switch valve and a first conversion connector from upstream to downstream, the first conversion connector is connected with the first short section, the tail end of the second short section is connected with an outlet pipeline, and the outlet pipeline is sequentially connected with a second conversion connector and a second switch valve from upstream to downstream. And the second adapter is connected with the second short section. On-line test research is ac
