The "2026 China Industrial Assembly and Fastening Industry White Paper" points out that China's industrial assembly and fastening industry has shifted from relying solely on scale expansion to a development phase centered on high-end, intelligent, and green practices. By the end of 2025, the industry's market size reached 167.5 billion yuan, characterized by "stable scale growth and structural transformation." This trend also holds significant implications for the chemical pump industry.

As core fluid transport equipment in devices such as petrochemicals, fine chemicals, new energy materials, and environmental water treatment, the reliable operation of chemical pumps depends not only on key components like pump bodies, impellers, bearings, and mechanical seals but also heavily on assembly precision and the stability of fastening systems. Under conditions of high temperature, high pressure, strong corrosion, flammability, explosion risks, and solid-containing media, positions such as flange connections, base fixings, bearing box assemblies, mechanical seal covers, coupling guards, and pipeline supports require high-strength, highly corrosion-resistant, and highly stable fasteners for support.

From the perspective of "structural transformation" emphasized in the white paper, the chemical pump industry should not only focus on flow rate, head, and efficiency but also prioritize overall machine assembly quality. Particularly in the context of major petrochemical plant overhauls, continuous production, and long-cycle operation, issues like fastener loosening, insufficient pre-tightening force, bolt corrosion, or assembly deviations can lead to vibration, seal leakage, bearing damage, or even safety accidents. Therefore, chemical pump manufacturers should strengthen standardized assembly, torque control, anti-loosening design, and material matching during the design and manufacturing stages.

In the future, as chemical equipment moves toward larger scale, intelligence, and domestic substitution, the requirements for high-performance fasteners and precision assembly processes in chemical pumps will further increase. By adopting corrosion-resistant fastening materials, standardized assembly procedures, digital inspection records, and intelligent condition monitoring, the operational reliability of chemical pumps can be effectively improved, maintenance costs reduced, and a solid guarantee provided for the safe, stable, and long-cycle operation of petrochemical plants.
