The ACP100 small reactor fluctuation tube was evaluated
The fluctuation tube of Linglong-1 (ACP100) small reactor developed by SINOMACH has passed the evaluation. After testing and inspection, the physical and chemical properties, surface quality, internal quality, final dimensions and other technical indicators of the fluctuating tube meet the requirements of the technical specifications and product drawings.
ACP100 is the world’s first onshore commercial modular small reactor, a multifunctional modular small pressurised water reactor with independent intellectual property rights, and another major achievement of independent innovation after Hualong No. 1. The wave pipe is an important pipe for adjusting and maintaining the pressure of the reactor’s first circuit, and is a key piece of equipment for the nuclear island. The key manufacturing technology developed by the Group’s subsidiary, Erzhong (Deyang) Heavy Equipment Co., Ltd. for the development of Linglong No. 1 (ACP100) small fluctuating pipe assessment can cover all fluctuating pipe products in Hainan Changjiang multi-purpose modular small reactor fluctuating pipe.
Successful hot-load commissioning of the designed strip unit
The one-time hot-load test run of the lead strip unit designed by SINOMACH for the silicon steel product yield improvement technology renovation project was successful, with the unit’s performance and product quality meeting the standards, laying the foundation for the smooth commissioning of subsequent projects.
The design and development of the lead strip unit is the responsibility of the Group’s subsidiary, China Heavy Machinery Research Institute Corporation. The unit is designed for a maximum production speed of 300m/min and a maximum production tension of 70kN, and can produce medium to high grade non-oriented silicon steel strips up to 1350mm wide and 1.8-3.0mm thick. The strip extrusion unit provides a new production method for medium and high grade silicon steel strips, with functions such as strip welding, strip heating and strip trimming, which improves the production efficiency and reduces the production cost of medium and high grade silicon steel strips. The lead strip unit can effectively promote the development of the generator and new energy vehicle industries in the process.
The project “R&D and application of Beidou-based distant sea intelligent integrated survey system (Phase I)” successfully passed the acceptance test.
The project “R&D and Application of Beidou-based Offshore Intelligent Integrated Survey System (Phase I)” undertaken by SINOMACH has successfully passed the acceptance inspection.
(hereinafter referred to as the “Research Institute”), a subsidiary of the Group, was mainly responsible for the development of the offshore drilling technology and equipment under the project. In the project, the Institute successfully developed a trolley-type lifting and sinking compensation system with a compensation stroke of 3m, a large-throughput top drive system suitable for rope coring and downhole static touch test (CPT) testing technology, and a new type of offshore engineering exploration equipment with a nominal drilling depth of 800m, with the overall technology reaching the international advanced level and some technologies leading the world.
Three self-developed equipment officially released
SINOMACH’s self-developed Eagle Series SP1350-3F paver, EVMS2500 Eagle Wing Screed and Hongwan Series HP835S-3F paver were officially launched. All three pieces of equipment were developed by Beijing Tianshun Great Wall Hydraulic Technology Co Ltd, a subsidiary of the Group.
The Eagle Series SP1350-3F paver is equipped with a 221kW National IV engine and can be equipped with the EVMS2500 large rigid screeding device, which is suitable for bridge and tunnel wide and variable working conditions and can improve the efficiency of continuous construction in working conditions such as bridges and tunnels where the road width changes frequently.
The EVMS2500 Eagle Wing is a large, rigid, oversized telescopic screed that can be assembled in a single pass with a 10m spread on both sides, reducing screed assembly time and work intensity. In addition, the machine is structurally optimised for rigidity and stability, as well as being free of assembly and retractable at the touch of a button.
The HP835S-3F paver is equipped with a one-touch full-width telescopic screeding device, which is suitable for municipal road maintenance and other operations.
The project “Key technology and industrial application of intelligent internal inspection for unconventional long-distance pipelines” led by SINOMACH passed the scientific and technological achievement appraisal
The project “Key technology of intelligent internal inspection of unconventional long-distance pipelines and industrial application” led by SINOMACH has passed the appraisal of scientific and technological achievements. The overall technology of the project reached the international advanced level, among which the maximum deformation, the minimum pressure required by the medium (gas pipeline), and the typical defects intelligent identification rate indicators reached the international leading level.
The project was led by Shenyang Instrument Scientific Research Institute Co., Ltd, a subsidiary of the Group, and jointly completed by other units. The project addresses the application scenarios and technical problems of intelligent internal inspection of unconventional long-distance pipelines, and for the first time proposes an adaptive umbrella-type skin bowl design structure, a gap magnetization design structure and near-saturated magnetic field measurement technology, a forward and reverse bi-directional smoothing pipeline centerline solution method based on multi-sensor data fusion, etc., which improves the adaptability of internal pipeline inspection instruments in unconventional pipelines and realizes the precise location of pipeline stress risk areas, and is essential for It is a support to enhance the localization rate of pipeline inspection equipment and to guarantee the structural integrity and safe operation of the pipeline body.
