Key features of ASTM A182 F51 S31803 JIS B2220 10K RF blind flange flanges

• Material: ASTM A182 F51 S31803 (Duplex Stainless Steel), known for its excellent corrosion resistance, strength, and resistance to pitting, making it suitable for harsh environments.
• Standard: Manufactured to JIS B2220 10K specification, ensuring compliance with Japanese industrial standards.
• Type: RF (Raised Face) blind flanges, ideal for sealing pipe ends or vessel openings.
• Size: Custom dimensions as per customer specifications.

Quality Assurance and Testing

We place great importance on quality and ensure each flange undergoes extensive testing before shipment. Our comprehensive quality control process includes:

1. Metallographic Structure Testing: To verify the integrity of the material’s grain structure and ensure it meets industry standards for strength and durability.
2. Hardness Testing: Ensuring the flanges have the proper hardness levels for resistance to wear and fatigue.
3. Spot Corrosion Testing: To confirm the resistance of the flanges to corrosion, particularly in marine and chemical environments.
4. Non-Destructive Testing (NDT): A range of tests, including ultrasonic and dye penetrant tests, to detect any internal or surface defects without damaging the flanges.
5. Low-Temperature Impact Testing: Tested at -46°C to ensure the material’s ability to perform under low-temperature conditions, with a minimum impact power of 35J to guarantee toughness and reliability.

Protection and Packing

To ensure the safety of the flanges during transportation, flange caps were used for protection. This additional step ensures that the flanges arrive at their destination without damage, maintaining their structural integrity and readiness for installation.
