Product Description

Cl Resistance 316L Stainless Steel Flange Ring

Corrosion Resistant Anti Pitting Design for Extreme Industrial Environments

Product Overview

Our 316L Stainless Steel Flange Rings are engineered for extreme environments where chloride-induced corrosion and pitting resistance are critical requirements.

Features & Specifications

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	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

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)
Pressure Rating: Class 150 to Class 2500 (ASME B16.5/EN 1092-1)

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

Key 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 retains material integrity without thermal distortion. 5-Axis CNC machining achieves 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

Industrial 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

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
