A Technical Tour of Shanghai Shenqi’s Manufacturing

The Heart of Safety Manufacturing

At the core of every reliable emergency shower and eyewash station lies a foundation of precision manufacturing. Shanghai Shenqi Machinery Equipment Co., Ltd. has established itself as a leading force in the safety equipment industry by integrating advanced technology with stringent quality control within its 2,800-square-meter manufacturing facility. This tour explores the key stages of Shenqi’s production process, highlighting how their infrastructure directly translates into the durability, compliance, and reliability of their products, from standard ANSI Z358.1-compliant showers to complex heat-traced systems for extreme environments.

Raw Material Management and Precision Cutting

The journey begins at the raw material storage area, where materials like 304 and 316 stainless steel are meticulously categorized and stored. Shenqi employs a scientific layout, positioning the cutting area adjacent to storage to optimize workflow. Utilizing advanced equipment such as a Plasma Flame Cutting Machine​ and Horizontal Band Saws, raw sheets and pipes are cut with high precision. This initial step is critical for ensuring dimensional accuracy in subsequent welding and assembly processes, forming the literal building blocks of robust safety equipment.
Advanced Welding and Forming Techniques

Welding is the cornerstone of Shenqi’s manufacturing integrity. The workshop is equipped with a range of TIG Welding Machines​ and Inverter Pulse Argon Arc Welding Machines​ operated by over 10 certified welders. The company holds ASME welding certificates​ and follows strict Procedure Qualification Records (PQR), ensuring every weld on a pressure vessel or shower pipe meets international standards. Complementing this, CNC Bending Machines​ and Hydraulic Presses​ allow for the accurate shaping of components, ensuring that every bend and contour in a shower frame or eyewash bowl is consistent and structurally sound.
Surface Treatment and Anti-Corrosion Protection

After fabrication, components undergo critical surface treatment to enhance durability and resistance to harsh industrial environments. A Sandblasting Machine​ is used to clean and prepare surfaces, creating an ideal profile for coating. Shenqi then applies specialized coatings, such as yellow electrostatic paint​ for high visibility and corrosion resistance. This process is vital for equipment destined for chemical plants or coastal areas, where exposure to corrosive elements is a constant challenge. The result is a finish that not only meets aesthetic standards but also significantly extends the product’s operational lifespan.
Meticulous Assembly and Quality Assurance

The assembly line is where individual components transform into fully functional safety systems. Here, skilled technicians assemble scald valves, eyewash nozzles, and push plates​ onto the main structure. Shenqi’s commitment to quality is evident in its rigorous inspection protocols. Each unit undergoes pressure testing to ensure leak-free performance. Furthermore, Positive Material Identification (PMI)​ is used to verify that all critical wetted parts, such as valves and pipes, are made from the specified stainless steel grade (e.g., SS316), guaranteeing material integrity and chemical resistance.

Testing, Packaging, and Global Dispatch

The final stage involves comprehensive testing and preparation for shipment. Units are subjected to a Factory Acceptance Test (FAT)​ that simulates real-world usage, checking water flow, coverage, and activation mechanism compliance with ANSI Z358.1​ and EN15154​ standards. Following approval, equipment is carefully packaged using custom-designed crates to prevent damage during international logistics. Shenqi’s proximity to the Yangshan Deepwater Port​ facilitates efficient dispatch to global clients, ensuring timely delivery to projects in the Middle East, Southeast Asia, and beyond.
Engineering Confidence in Every Product

A tour of Shanghai Shenqi’s facility reveals more than just a production plant; it showcases a integrated system where engineering expertise, quality materials, and rigorous processes converge. This controlled environment is the reason why Shenqi’s emergency showers and eyewash stations offer unwavering reliability in critical moments. From the initial plasma cut to the final packaging strap, every step is a testament to the company’s dedication to protecting worker safety worldwide through superior engineering and manufacturing excellence.
