1. Precision Cutting: Utilizing CNC precision cutting equipment, raw materials are precisely cut according to standard specifications and customized requirements. Strict control over dimensional tolerances ensures the accuracy of subsequent forging, mitigating dimensional deviations from the outset and laying a solid foundation for later processes

2. High-Temperature Die Forging: The cut billets are fed into specialized high-temperature forging equipment. Through a closed-loop hot forging precision shaping process, a single forging operation forms the entire pipe. The forging temperature, pressure, and time are controlled throughout the process to ensure a dense overall structure, eliminating splices and welds, and guaranteeing consistent pressure resistance across the entire pipe.

3. Heat Treatment Strengthening: After forging, the pipes undergo professional normalizing and tempering treatments. Precise temperature control refines the metallographic crystal structure, eliminates internal stress generated during forging, and enhances the pipe's impact resistance, creep resistance, and deformation resistance, extending product lifespan.

4. Surface Treatment: A non-destructive grinding process is used to remove oxide scale, burrs, and surface defects generated during forging, resulting in a smooth and flat surface. Rust prevention treatment is also applied to enhance corrosion resistance and adaptability to various installation environments.

5. Precision Machining: High-precision CNC equipment is used to precision machine the socket ports and internal flow channels, strictly controlling port dimensional tolerances to the micron level. This ensures a tight fit and smooth, unobstructed flow, meeting the needs for rapid on-site connection and efficient media delivery.

6. Comprehensive Inspection: Each batch of pipe fittings undergoes comprehensive inspection, including pressure testing, dimensional verification, and visual inspection. Defective products are eliminated, ensuring that every product meets industry standards and quality requirements, guaranteeing product safety and compliance.

7. Compliant Packaging: After passing inspection, the pipe fittings are marked with compliant identification codes indicating product specifications, standards, and production batch information. They are then sealed and packaged in moisture-proof and rust-proof packaging materials for easy storage, transportation, and on-site acceptance and traceability.
