Stainless steel press fittings, known for their hygienic, corrosion-resistant, high-strength, long lifespan, quick installation, and reliable sealing, are widely used in water supply, gas supply, and other industrial applications. Their quality directly determines the safety and lifespan of the entire system. Today, let’s explore the journey of a high-quality stainless steel compression fitting at DINSEN’s smart factory and see how it’s meticulously crafted to protect your life. DINSEN Press Fittings Stainless Steel Core Advantage:
1. Food-Grade Raw Materials, Worry-Free
DINSEN strictly selects high-quality 304/316 austenitic stainless steel coils and billets that comply with national standards such as GB/T 12771. These food-grade materials, with precisely defined chromium and nickel content, inherently offer excellent corrosion resistance and hygienic properties, ensuring pure and safe water quality from the source.
Automatic CNC equipment performs high-precision cutting, ensuring dimensional tolerances of less than 0.1mm for pipe stock, laying a solid foundation for subsequent precision forming.
2. No Welds, Doubled Strength
Cold Extrusion/Stamping: Under immense pressure, metal billets are cold-extruded or stamped into pipe bodies (such as elbows, tees, and straight fittings) in precision dies. DINSEN utilizes advanced processes to eliminate welds in key locations, completely eliminating potential weld corrosion and leakage risks, and increasing structural strength by over 30%.
Detailed Finishing: Smooth and evenly finished ports ensure smooth insertion and a uniform seal.
3. Deep Corrosion Resistance, Doubled Lifespan
Scientific Heat Treatment: After forming, the pipes undergo solution treatment in a precision protective atmosphere at 1050-1100°C.
Performance Enhancement: This process eliminates internal stresses and dissolves carbides, making the stainless steel structure more uniform and stable. This significantly improves corrosion resistance and mechanical toughness, resulting in a service life of over 70 years, far exceeding that of standard products.
4. Ultra-Smooth Interior Surface for Unimpeded Water Flow
Internal and External Polishing: Mechanical or electrolytic polishing processes are used to create a mirror-like inner surface (Ra ≤ 0.4μm), significantly reducing water flow resistance and preventing microbial growth. This makes it particularly suitable for high-hygiene environments such as medical and food processing.
External Surface Treatment: The exterior surface is brushed or polished for aesthetic appeal and easy cleaning, enhancing the overall quality of the project.
5. Zero Leakage Guarantee
CNC Carving: Precision CNC equipment machines a U-shaped compression groove with highly uniform depth, angle, and position at the pipe socket. Sealing Core: This groove is the “soul” of the press-fit connection. DINSEN’s scientifically designed groove ensures uniform compression of the dedicated sealing ring, creating a triple seal (radial, end face, and axial), achieving zero leakage and pull-out resistance far exceeding standard requirements.
6. Infallible Quality Control
Full-Process Testing: Dozens of rigorous tests are conducted across the entire process, including raw materials, dimensions, appearance, pressure, airtightness, and salt spray corrosion.
Traceability System: Each batch of products is uniquely identified, ensuring full traceability of quality and ensuring safety accountability.
