Feature (F)、Advantage (A)、Benefit (B)

1. Raw Materials:

• F:The product uses food and pharmaceutical grade 304 and 316L refined stainless steel raw materials.Genuine industrial-grade stainless steel billets are selected, featuring pure composition, no impurities, no internal defects, and stable chemical performance. The material complies with sanitary contact material standards.
• A:The material provides excellent corrosion resistance, oxidation resistance, rust resistance, and noparticle shedding. Compared with ordinary low-quality stainless steel, it effectively improves problems such as corrosion, metal precipitation, and material degradation, reducing the risk ofmedium contamination and pipeline oxidation damage while enhancing overall durability andstability.
• B: The product ensures that materials, pharmaceutical liquids, and purified water media remain cleanand contamination-free. It complies with GMP and food/pharmaceutical production regulations,helping prevent product waste and quality inspection failures while improving production safety and compliance

2. Processing Technology:

• F:The product adopts integrated forging and forming technology with no welding joints or assemblyseams. The flange surfaces and bolt holes are precision machined by CNC turning. Internal andexternal surfaces receive fine mirror polishing treatment. The flange faces are flat and uniform, andevery product undergoes pressure testing, flaw detection, and cleanliness inspection before delivery.
• A: This process improves common defects found in ordinary elbow flange products, such as flange surface deformation, inaccurate hole positions, rough polishing, and welding dead corners. Itreduces material accumulation areas, sealing failures, and installation misalignment problems,greatly improving product precision, cleanliness, and assembly compatibility.
• B:Installation requires no secondary correction. Connections fit precisely, reducing installation reworkcosts. The pipeline is easier to clean and sterilize, with reduced bacterial residue, meeting high-end clean productionacceptance standards. 

3. Structural Design:

• F: The product adopts an integrated structure consisting of a 90° arc-shaped elbow and sanitary flanges on both ends. The flow channel is smooth and rounded. The flange surfaces are flat without uneven areas, and bolt holes are standardized and symmetrically arranged, providing a stable structure that resists deformation.
• A:The smooth arc transition reduces fluid transportation resistance, turbulence, and wear. The seamless integrated structure provides high strength, impact resistance, and fatigue resistance,allowing long-term exposure to high-pressure and high-temperature media. It is suitable for industrial pipeline transportation under continuous operating conditions.
• B: Pipeline transportation becomes smoother, reducing fluid energy consumption and medium loss. Itdecreases local pipeline wear and perforation problems, extends the service life of the entire pipeline system, and lowers future modification and replacement costs.

4. Features and Advantages:

• F: The product provides comprehensive sanitary performance including high cleanliness, no deadcorners, high sealing performance, high pressure resistance, repeated disassembly and installation capability, temperature resistance, and corrosion resistance. It is suitable for high-frequency CIPcleaning and high-temperature sterilization operating conditions.
• A: It reduces problems such as bacterial growth, medium residue, interface leakage, and pipeline deformation or damage. It improves pipeline cleanliness, pressure-bearing capability, operational stability, and service life, making it suitable for large-diameter and high-load clean pipeline applications.
• B:Production line operation becomes more stable with lower failure rates, reduced downtime, and lessmaterial loss. It effectively improves production yield and reduces long-term operation,
  maintenance, and pipeline replacement costs.

5. Sealing Ring Features:

• F:The product is equipped with sanitary food-grade sealing gaskets. Optional materials include silicone, EPDM, and PTFE. These materials are non-toxic, odorless, highly elastic, temperature-resistant, and corrosion-resistant, making them suitable for flange flat-face sealing applications
• A:The gasket fits tightly against the flange surface without gaps. It provides pressure resistance, aging resistance, and deformation resistance, improving common problems found in ordinary sealing components, such as corrosion, aging, and sealing failure. This enhances interface sealing stability and high-temperature sterilization performance.
• B:The flange connection provides zero leakage and zero contamination. It prevents material wasteand hygiene risks in production areas. The sealing components have a long service life, reducing consumable replacement costs and maintenance downtime.
