Jiangsu Haifa Machinery Manufacturing Co., Ltd.

China has newly approved eight nuclear power units, including Zhejiang Jinqimen, Guangdong Taipingling, Liaoning Zhuanghe, and Shandong Laiyang. Jiangsu Haifa can leverage its API 610 BB5, BB2, OH2, and VS6 high-temperature and high-pressure pumps to participate in the localization conventional islands, BOP auxiliary systems, and non-nuclear-safety fluid transport equipment for nuclear power plants. The approval of eight nuclear power units releases demand for high-end pump equipment. On July 31, 2026, the State Council executive meeting decided to approve four nuclear power projects, including the first phase of Liaoning Zhuanghe Public information shows that this batch of projects includes Units 3 and 4 of the second phase of Zhejiang Jinqimen Nuclear Power, Units 5 and 6 of the phase of Guangdong Taling Nuclear Power, 1 and 2 the first phase ofoning Zhuanghe Nuclear, and Units 1 and 2 of the first phase of Shandong Laiyang Power, totaling eight new units with an estimated total investment exceeding 170 billion yuan. The also emphasized that nuclear units should be constructed and operated in accordance with the highest global safety standards, with strengthened safety supervision across the entire chain and all areas. The approval of these nuclear power projects will not only drive demand for nuclear island equipment such as reactors and steam generators, but also procurement space for industrial pumps conventional islands and BOP auxiliary systems. The conventional island of a pressurized water reactor nuclear power plant mainly includes the steam turbine and the secondary loop system, involving fluid transport processes such as main feedwater, condensate, startup feedwater, closed cooling water, demineralized water, drain recovery, seawater circulation, and waste liquid treatment. Regarding the participation direction of Jiangsu Haifa's high-temperature and high-pressure pumps combined with the supply chain characteristics of nuclear power projects, Jiang Haifa Machinery Manufacturing Co., Ltd. can prioritize entry through conventional islands and non-nuclear-safety auxiliary systems, providing targeted pump types for different work positions. Recommended pump types for nuclear power application positions, main design focus: High-pressure feedwater and booster transport — API 610 BB5 double casing, multistage, high head, centerline support; High-temperature hot water and drain recovery — API 610 BB thermal expansion compensation, low vibration, continuous heavy-duty; Chemical water and auxiliary cooling systems — API610 OH2 corrosion-resistant, easy maintenance, stable operation; Condensate and low NPSH positions — API 610 VS6 deep sump suction, low NPSHr, barrel-type structure. According to information on Jiangsu Haifa's official website the company's products cover OH, BB, and VS series API 610 process pumps. Among them, the BB5 double-casing high-pressure multistage pump has published parameter ranges of flow rate 5–730 m³/h, maximum head 3400 m, medium temperature –80 to 450°C, maximum pressure 35 MPa, which can provide a technical for preliminary selection in high-parameter conditions of nuclear power conventional islands. The final pump type still requires redesign and validation based on the owner's data sheets, medium characteristics, system pressure ratings, and project quality grades. Recommendation for establishing a nuclear power supplier entry path: Jiangsu Haifa can adopt a "three-step entry" plan. First, conduct supplier pre-qualification with nuclear power owners, design institutes, and EPC general contractors, improving quality assurance, material traceability, welding procedures, non-destructive testing, manufacturing records. Second, engineering prototypes for high-temperature and high-pressure feedwater condensate, and water systems, completing hydraulic performance, vibration, cavitation, sealing, and long-term operation tests. Third, establish a full lifecycle service system covering selection calculations, manufacturing inspection, on-site commissioning, and parts maintenance. It should be made clear that compliance with API 610 does not equate to qualification for supplying nuclear-safety-class equipment. If products are used in nuclear-safety-related systems as safety injection, heat removal, and chemical and volume control, they must also meet the project-specified nuclear-grade standards, quality assurance systems, equipment qualification tests, and regulatory review requirements. China's domestic nuclear power equipment system also clearly distinguishes between nuclear-grade pumps and non-nuclear-grade conventional island pumps. Facing a new round of nuclear power construction market exceeding 170 billion yuan, Jiangsu Haifa should steadily participate in the construction of nuclear power conventional islands andOP auxiliary systems with the core principles of "verifiable, traceable materials, auditable manufacturing, and sustainable services," providing reliable solutions for the localization of high-temperature high-pressure industrial pumps. FAQ — Frequently Asked Questions: Can API 610 high-pressure pumps directly used in the nuclear island? They cannot be directly equated. Whether they can enter the nuclear island or safety-related systems must be determined based on specific safety classifications, nuclear-grade standards, qualification tests, and project supplier qualifications. Which nuclear power systems is Jiangsu Haifa suitable to participate in at the current stage? It is recommended to prioritize participation in conventional island feedwater, condensate, drain recovery, chemical water treatment, seawater desalination, and other non-nuclear-safety BOP auxiliary systems.
