Recently, Chengde Jianlong Special Steel Co., Ltd. (hereinafter referred to as Jianlong Steel) Φ114.3～Ф339.7 and Pangang Group Sichuan Changcheng Special Steel Co.,Ltd. (hereinafter referred to as Changcheng Steel) Φ76～Ф245 hydraulic testing machine and drifting device, which were supplied by Sino-heavymach were passed hot test successfully one-time. All indicators met the design requirements, won unanimous praise from users and put into operation successfully.
Both sets of equipment adopt a series of advanced technologies such as toggle-type water filling device, automatic positioning exhaust device and automatic pneumatic drift of Sino-heavymach to ensure efficient and stable production for users; At the same time, the hydraulic system adopts a servo control system, compared with the traditional system, the energy saving is more than 50% and the noise is reduced by 40%, which greatly improves the on-site production environment of users.
The successful operation of the Jianlong Steel hydraulic testing machine project plays an important role in promoting Jianlong Group to successfully obtain the high-quality steel pipe manufacturer certification, enhance product competitiveness and achieve its goal of becoming a global leader in energy steel. The successful operation of the hydraulic testing machine of Changcheng Steel provides the test basis for the safety of its nuclear power military pipe, which is of great significance to its product upgrading.
The successful operation of the two projects is the result of Sino-heavymach's dedicated R&D and continuous optimization of design and improvement in the field of hydraulic testing and drifting device. Further consolidate the technology leading position of Sino-heavymach in the research and development field of steel pipe pressure testing.
