Stainless Steel Blind Flange ANSI/GB/DIN SS304/316L PN16
SS316 stainless steel
Product Features
1. Material: High-quality SS304 (AISI 304) / SS316L (AISI316L) stainless steel, excellent resistance to acid, alkali and corrosion.
2. Standard compliance: Manufactured in accordance with ANSI B16.5, GB/T 9123, DIN 2520 to ensure dimensional accuracy and interchangeability.
3. Sealing performance: Precision-machined sealing face(FF/RF/RTJ type) matches with gaskets for leak-proof operation.
4. Surface treatment: Pickling passivation (standard) or mirror polishing (optional for sanitary use), ensuring smooth surface and rust prevention.
5. Durability: Forged or plate-cut construction, high tensile strength, suitable for high-pressure (PN10-PN40) and high-temperature (-20℃~400℃) working conditions.
