Corrosion Resistant Stainless Steel Flange Rings (Cl⁻ Resistance) 316L Stainless Steel Custom Anti Pitting Design
1,Product Overview
Our 316L Stainless Steel Flange Rings are engineered for extreme environments where chloride-induced corrosionand pitting resistance are critical.
2,Features & Specifications
1. Advanced Material Properties
Material: 316L Stainless Steel (Low Carbon, High Molybdenum Content)
Composition: Cr 16-18%, Ni 10-14%, Mo 2-3%, C ≤0.03%
Corrosion Resistance:
Chloride Resistance: Withstands >1,000 ppm Cl⁻ (ASTM G48 Method A Testing).
Pitting Resistance Equivalent (PRE): ≥35 (Calculated as %Cr + 3.3×%Mo + 16×%N).
Mechanical Properties:
Tensile Strength: ≥485 MPa | Yield Strength: ≥170 MPa | Hardness: ≤217 HB.
Certifications: ASTM A240, NACE MR0175, PED 2014/68/EU.
2. Precision Engineering
Design Flexibility: Customizable bolt patterns, facings (RF/FF/RTJ), and non-circular profiles.
Dimensional Accuracy:
Bolt Hole Positioning: ±0.3mm | Outer Diameter: ±1.0mm.
Surface Treatment:
Electro-polishing (Ra ≤0.4μm) or Passivation (ASTM A967) for enhanced corrosion barrier.
Pressure Rating: Class 150 to Class 2500 (ASME B16.5/EN 1092-1).
3. Technical Specifications
Size Range: 1/2" to 36" nominal bore (Custom sizes available).
Temperature Range: -196°C to 800°C (Cryogenic to high-temperature compatible).
Interoperability: Compatible with ASTM A182 F316L forgings for welded assemblies.
3,Advantages
✅ Chloride Resistance
316L’s molybdenum-enriched matrix prevents pitting and crevice corrosion in seawater, brine injectors, and acidic media.
✅ Zero Post-Weld Degradation
Low carbon content (<0.03%) eliminates carbide precipitation during welding, ensuring intergranular corrosion resistance.
✅ Hybrid Manufacturing
Cold Forming/Welding: Retain material integrity without thermal distortion.
5-Axis CNC Machining: Achieve complex geometries and tight tolerances.
✅ Full Traceability
Mill Test Reports (MTRs) with heat number tracking.
100% PT (Dye Penetrant) and PMI (Positive Material Identification) testing.
4,Applications
Offshore & Marine: Subsea pipelines, seawater cooling systems, shipboard fittings.
Chemical Processing: Chlor-alkali reactors, acid storage tanks, bleach production.
Desalination Plants: Reverse osmosis (RO) modules, brine discharge flanges.
Pharmaceutical: CIP/SIP systems, high-purity fluid transfer.
Oil & Gas: H₂S/CO₂-laden wellheads, LNG cryogenic piping.
5,Manufacturing Process
1. Material Selection:316L steel sourced from ISO-certified mills
2. Forming:Cold rolling/pressing or TIG welding (for large sizes).
3. Machining:5-axis CNC for bolt holes, grooves, and sealing faces. ±0.3mm positional accuracy.
4. Surface Treatment:Electro-polishing or nitric acid passivation.
5. Quality Control:PMI, PT/UT testing, 3D CMM for dimensional verification.
