精心打造“安全血管”——河北申王为安徽长鑫晶圆项目构筑消防管网基石

在安徽长鑫晶圆项目的消防安全保障体系中，七氟丙烷管网灭火系统扮演着守护核心设施的“安全血管”角色。河北申王精密机械制造有限公司凭借精湛工艺，专注于集流管等关键部件的生产，通过一系列精细工序，为项目构建了坚实的消防屏障。

一、集流管生产：从原料到成品的精工雕琢

（一）精准下料 —— 奠定精度基础

选用国标高品质无缝钢管，按照集流管设计规格，利用数控激光切割设备进行下料。激光束如同精确的手术刀，将管径误差严格控制在±0.3mm以内，切口平整光滑，为后续加工打下精确的尺寸基础，确保整体管网的适配性不受下料偏差影响。

（二）科学开孔 —— 把控关键环节

运用激光切管机进行开孔作业，针对七氟丙烷管网灭火系统的接口需求，精确地定位开孔位置。开孔直径公差控制在±0.1mm内，孔壁经过倒角处理，去除毛刺，既保证了与支管连接的密封性，又便于后续焊接操作，确保每一个接口都成为可靠的连接点。

（三）规范破口 —— 优化焊接前提

采用专用破口设备，对集流管管口及开孔边缘进行破口处理。破口角度严格遵循焊接工艺要求，呈现出均匀、规整的坡面，增加了焊接接触面积，为后续精密焊接创造了有利条件，确保焊接强度与密封性均达到标准。

（四）精密焊接组装 —— 筑牢质量防线

焊接工序是集流管生产的核心环节。持证焊工采用氩弧焊工艺，在无尘焊接车间进行作业。焊接参数（电流、电压、焊接速度）精准设定，焊接过程中实时监测温度场，确保焊缝成型均匀、无气孔、夹渣。在多段集流管组装时，使用高精度工装夹具定位，同轴度误差控制在极小范围内，使得集流管成为坚固、严密的整体。

（五）热镀锌处理 —— 增强耐腐性能

完成焊接组装的集流管进入热镀锌工序。将集流管浸入高温锌液中，使其表面形成均匀、致密的镀锌层。镀锌层厚度达到行业高标准，有效提升了集流管的抗腐蚀能力，即使在潮湿、复杂环境中，也能保证长期稳定运行，为消防系统的使用寿命提供保障。

（六）喷塑工艺 —— 兼具防护与标识

热镀锌后的集流管进行喷塑处理。选用优质消防专用红色塑粉，通过静电喷涂工艺，使塑粉均匀附着在集流管表面。塑粉涂层厚度适中、附着力强，不仅进一步增强了防腐性能，醒目的红色也符合消防设施的标识规范，使得集流管在发挥功能的同时，实现了直观识别。

二、管网配套生产：与集流管协同适配

除了集流管，管网其他管道的生产同样严格。管材切割、焊接、表面处理等环节，均遵循与集流管一致的高精度标准。管道与集流管接口经过专项适配检测，确保管径、螺纹、焊接面精准匹配，保障七氟丙烷灭火介质输送的顺畅，使整个管网系统成为协调统一的“安全传输网络”。

三、安装调试：精准衔接，验证品质

在安装现场，施工团队依据生产精度，迅速完成管网搭建。安装过程中，利用水平仪、扭矩扳手等工具，确保管道水平度、连接紧固度。调试环节简化流程，专注于压力测试、系统联动基本功能验证，快速确认管网在实际场景中能稳定运行，以简洁高效的方式，验证生产环节铸就的品质。

河北申王以集流管生产为核心，通过下料、开孔、焊接、表面处理等全流程精细工艺，为安徽长鑫晶圆项目七氟丙烷管网灭火系统打造了高质量的“安全血管”。从生产车间的精工细作，到现场安装调试的精准验证，每一步都体现了对品质的执着追求，为半导体高端项目的消防安全筑牢了坚实根基，护航产业安全发展之路！

Meticulously Crafting the "Safety Vessels" —— Hebei Shenwang Lays the Foundation for the Fire-fighting Pipe Network of Anhui ChangXin Wafer Project In the fire safety protection system of the Anhui ChangXin Wafer Project, the gaseous fire suppression system with heptafluoropropane pipe network plays the role of "safety vessels" to protect the core facilities. Hebei Shenwang Precision Machinery Manufacturing Co., Ltd., with its exquisite craftsmanship, focuses on the production of key components such as manifold tubes. Through a series of meticulous processes, it has built a solid fire protection barrier for the project. I. Manifold Tube Production: Exquisite Carving from Raw Materials to Finished Products (1) Precise Cutting —— Laying the Foundation for Precision High - quality seamless steel pipes meeting national standards are selected. According to the design specifications of the manifold tube, CNC laser cutting equipment is used for cutting. The laser beam, like an accurate scalpel, strictly controls the diameter error within ±0.3mm. The cut surface is flat and smooth, laying an accurate dimensional foundation for subsequent processing and ensuring that the adaptability of the overall pipe network is not affected by cutting deviation. (2) Scientific Drilling —— Grasping the Key Link A laser pipe cutting machine is used for drilling operations. For the interface requirements of the heptafluoropropane pipe network fire - fighting system, the drilling positions are accurately located. The diameter tolerance of the holes is controlled within ±0.1mm. The hole walls are chamfered to remove burrs, which not only ensures the sealing performance of the connection with the branch pipes but also facilitates subsequent welding operations, ensuring that each interface becomes a reliable connection point. (3) Standardized Beveling —— Optimizing the Welding Premise Special beveling equipment is used to bevel the pipe ends of the manifold tube and the edges of the holes. The bevel angle strictly follows the requirements of the welding process, presenting a uniform and regular slope surface, increasing the welding contact area, creating favorable conditions for subsequent precision welding, and ensuring that both the welding strength and sealing performance meet the standards. (4) Precision Welding and Assembly —— Building a Solid Quality Defense Line The welding process is the core link in the production of manifold tubes. Certified welders use the argon arc welding process and work in a dust - free welding workshop. The welding parameters (current, voltage, welding speed) are precisely set. The temperature field is monitored in real - time during the welding process to ensure that the weld bead is uniformly formed without pores or slag inclusions. When assembling multiple - section manifold tubes, high - precision fixture tools are used for positioning, and the coaxiality error is controlled within a very small range, making the manifold tube a solid and tight whole. (5) Hot - dip Galvanizing Treatment —— Enhancing Corrosion Resistance The welded and assembled manifold tube enters the hot - dip galvanizing process. The manifold tube is immersed in high - temperature zinc liquid, and a uniform and dense galvanized layer is formed on its surface. The thickness of the galvanized layer reaches the high standard of the industry, effectively improving the corrosion resistance of the manifold tube. Even in a humid and complex environment, it can ensure long - term stable operation and provide guarantee for the service life of the fire - fighting system. (6) Powder Coating Process —— Both Protection and Identification After hot - dip galvanizing, the manifold tube undergoes a powder coating treatment. High - quality red powder specifically for fire - fighting is selected. Through the electrostatic spraying process, the powder is evenly attached to the surface of the manifold tube. The powder coating layer has a moderate thickness and strong adhesion, which not only further enhances the anti - corrosion performance, but also the eye - catching red color conforms to the identification specifications of fire - fighting facilities, enabling the manifold tube to achieve intuitive identification while performing its functions. II. Pipe Network Supporting Production: Coordinated Adaptation with Manifold Tubes In addition to manifold tubes, the production of other pipes in the pipe network is also carried out with strict standards. The processes of pipe cutting, welding, and surface treatment all follow the same high - precision standards as those of manifold tubes. The interfaces between the pipes and the manifold tubes are subject to special adaptation tests to ensure that the pipe diameters, threads, and welding surfaces are precisely matched, ensuring the smooth transportation of the heptafluoropropane fire - extinguishing medium and making the entire pipe network system a coordinated and unified "safe transmission network". III. Installation and Commissioning: Precise Connection, Verifying Quality At the installation site, the construction team quickly completes the construction of the pipe network based on the production precision. During the installation process, tools such as levels and torque wrenches are used to ensure the levelness of the pipes and the tightness of the connections. In the commissioning stage, the process is simplified, focusing on pressure testing and the verification of the basic functions of system linkage, quickly confirming that the pipe network can operate stably in the actual scenario. In a simple and efficient way, the quality forged in the production process is verified. Taking the production of manifold tubes as the core, Hebei Shenwang has created high - quality "safety vessels" for the heptafluoropropane pipe network fire - fighting system of the Anhui ChangXin Wafer Project through the whole - process fine craftsmanship of cutting, drilling, welding, and surface treatment. From the meticulous work in the production workshop to the precise verification of on - site installation and commissioning, every step reflects the persistent pursuit of quality, firmly laying a solid foundation for the fire safety of high - end semiconductor projects and escorting the safe development path of the industry!
