Description
Technical Field
The invention belongs to the technical field of pipeline steel welding, and particularly relates to a post-welding data acquisition device for high-strength long-distance pipeline steel.
Background
Petroleum and natural gas are main energy sources and important strategic resources for national economic development. Because pipeline transportation has the advantages of safety, economy, high efficiency and the like, the pipeline transportation of petroleum and natural gas has become a preferred technical scheme at home and abroad. In recent years, with the rapid development of oil and gas pipeline construction, pipeline steel is becoming the fastest and most active part of low-alloy high-strength steel, and is continuously developing towards the directions of long distance, large pipe diameter, high pressure and high strength and toughness so as to reduce the pipeline construction cost and improve the oil and gas transmission efficiency and safety, and welding is a key and core technology of modern manufacturing industry. No matter in the pipe-making shaping, the pipeline is laid and installed on site, or in the pipeline maintenance process, the pipeline steel is realized by welding. At present, the pipeline steel coil plate with enough toughness can be provided through micro-alloying, ultra-pure smelting, modern controlled rolling and controlled cooling technology and the like. At present, in the construction of long-distance pipelines, pipeline steel connection still mainly adopts electric arc welding, and because the energy density and the penetration capability of the electric arc welding technology are relatively strong, the toughness of a welding joint is insufficient due to residual stress, excessively large crystal grains and formation of a poor structure in the welding joint of the pipeline steel, so that the service reliability and the durability of an oil-gas pipeline are seriously influenced. Therefore, the structure, stress and distribution state of the high-grade pipeline steel welding head become the core content of the accurate regulation and control of the toughness performance of the welding head, particularly, along with the improvement of the strength grade and the pressure of oil and gas transmission, the toughness required by the pipeline steel is higher, and how to ensure the high toughness and the embrittlement prevention of the welding head is one of the key factors for ensuring the safety of an oil and gas transmission pipeline, so the prior art provides an impact rolling method along with welding, the principle of which is that rolling or impacting is carried out on the welding position after welding through a rolling wheel or other elements, the longitudinal and transverse compressive plastic strain of welding metal and the transverse compressive strain of welding metal caused by a front wheel are fully expanded, thereby achieving the purpose of controlling the welding residual stress and deformation, according to the experimental data in the new method of controlling the welding stress deformation along with welding impact rolling, which is disclosed in the journal of China in 2004, New method of mechanical engineering, No. 40, the impact rolling along with welding can obviously eliminate the residual stress of the workpiece, reduce the deformation amount and simultaneously improve the tensile strength, thereby effectively improving the performance of a welding joint.
In order to further improve the optimization of welding joints by welding and rolling, the applicant and the team thereof achieve the rolling pressure by obviously increasing the rolling pressure and weld the pipeline steel by welding and rolling, but because the technology is blank, the applicant and the team thereof carry out a plurality of experiments on different welding parameters, and in the test process, the inventor finds that the pipeline steel has certain thickness and always needs to be welded from two surfaces, namely the inner side and the outer side, so that the residual stress on the inner wall and the outer wall of the welding joint part of the pipeline steel needs to be measured, and the optimal test parameters are judged, and the prior art adopts residual stress detection equipment, which is mature prior art, such as: the residual stress check out test set of multiple different principles such as X-ray diffraction, ultrasonic wave, but these equipment are directed against the flat plate design more, its support is exactly common tripod, when in actual use, can detect the welding seam of the outer wall of pipeline steel, but can't detect the welding seam of inner wall, it can only the people creep into the pipeline steel to detect inboard welding seam, handheld device carries out the collection of data, under experimental conditions, this kind of method is comparatively inconvenient, and in actual production, the length of pipeline steel is longer, if let the user creep and go to gather the welding seam data, it is unrealistic obviously, and the ventilation is not smooth in the long tube, still remain higher temperature in the postweld pipe, can't guarantee long-time work.
