Problems solved by technology

Due to long-term exposure to such harsh conditions, there is a danger of fine cracks inside the pipeline material. If it is not dealt with and controlled, it will affect the strength of the pipeline and reduce its life. An important prerequisite for the performance test of offshore oil pipelines, the workload is heavy, the cycle is long, relying solely on manual work, the efficiency is low, and accidents are prone to occur
At present, there is no system and method for automatic testing of offshore oil pipelines

Abstract

The invention relates to an electrical system and a test method for a PLC control-based marine oil pipe dynamic tester. The system comprises a PLC control system, and a dynamic test device and a touch screen which are connected with the PLC control system; and the PLC control system communicates with the touch screen through PROFIBUS. The test method comprises bending test, torsion test and tensile test. The system and the method have the advantages of basic realization of automatic test, realization of saving of the land, a lot of manpower and a lot of time through integrating three test functions of bending, torsion and tension, increase of the accuracy, guaranteeing of the safety of workers, and great increase of the production efficiency.

Description

Technical field [0001] The invention belongs to the field of automatic control applications, and relates to a PLC-based offshore oil pipeline dynamic tester electrical system and a test method thereof, and specifically relates to the integration of automatic control by Siemens S7 300 series PLC control system, TP1200 Comfort touch screen and dynamic test equipment System, PROFIBUS bus and PID closed-loop control algorithm are combined and other technologies are used for dynamic fatigue testing of marine oil pipelines. Background technique [0002] my country's oceans have very rich reserves of petroleum resources. With the increasing demand for consumption, high-speed and safe connection of offshore oil fields and onshore oil industry systems has become a top priority. The offshore oil pipeline can continuously transport a large amount of crude oil and is the fastest, safest, economical and reliable transportation method. [0003] The offshore oil pipeline is an important part of ...
