Happy New Year 2024 **********************【Ten Years of Rapid Development in Chemical Processing Equipment】A continuously updated summary post – feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Industry Forum) ***************** In January 2024, Nutok’s large-diameter, high-pressure metal hard-sealed slurry ball valves played a key role in ensuring the successful operation of Indonesia’s first long-distance slurry transport pipeline for laterite nickel mining. The long-distance pipeline transportation project for nickel-cobalt slurry in Indonesia is a crucial link between the mines and smelters. The total length of the slurry pipelines in the field for this project is approximately 62 km. The valve specifications are DN600 and DN550, with a CLASS-600LB rating; they are connected using flanges, and the actuation method is electric. The pipeline starts at the slurry transfer pump station in the mine processing area, and ends at the energy dissipation station in the smelting plant area by the sea. Along its course, it passes through tropical rainforests, crosses towering mountains, and goes over numerous roads and rivers. The slurry transfer pump station is equipped with 6 high-flow, high-pressure diaphragm pumps. The terminal energy dissipation station is large in scale and features multiple energy dissipation modes. The large-diameter, high-pressure metal hard-sealed slurry ball valve is a key control device in such slurry long-distance pipeline transportation systems, and it plays a crucial role in the long-term safe and stable operation of these pipeline systems. The core technology behind such ball valves has been under the monopoly of foreign companies for a long time; it is therefore urgent to enhance domestic R&D capabilities, acquire independent intellectual property rights, reach international standards in terms of design and manufacturing, and achieve breakthroughs in all relevant indicators. NiuTock has established comprehensive strategic partnerships with institutions such as the Institute of Metal Research of the Chinese Academy of Sciences and Shenyang Institute of Industrial Technology, founding the NiuTock Innovation Technology Institute. By introducing innovative mechanisms and systems, it attracts various innovative resources to carry out cutting-edge research and development in the field of high-end control valves. Since its introduction, the domestically developed large-diameter, high-pressure metal hard-sealed slurry ball valve produced by Nutok has quickly captured a share of the international market thanks to advantages such as short delivery times and low maintenance costs. It provides domestic ball valves that are stable in performance and safe to use for overseas system projects, earning high recognition from clients abroad. In the future, Nutok will continue to rely on technology as a driving force, innovate service models, and accelerate the application of its products in fields such as petroleum and new energy, natural gas, petrochemicals, coal chemicals, silicon chemicals, and metallurgy. It aims to speed up the substitution of imported high-end valves and contribute to the achievement of the strategy of becoming a strong manufacturing nation.
