Inconel 625 Cladding Flange ASTM A694 F52 Carbon Steel Cladding Weld Neck Flange

B16.5 ASTM A694 / ASME SA694 F52 with Inconel 625 Cladding Flanges

A cladded flange undergoes weld overlay cladding, a process similarly applied to pipelines and associated components (e.g., pipes, fittings, plates, tubesheets). This technique creates a bonded, corrosion-resistant layer on surfaces exposed to corrosive or erosive environments, extending service life in demanding industrial applications

To ensure accurate quoting and avoid costly revisions, the client should provide below inquiry information of cladding flange:

1. Base Material & Specifications

• Base Metal Grade: e.g., SA105 (carbon steel), SA182 F316L (stainless)

• Standard: ASME, ASTM, EN, etc. (e.g., ASME B16.5, ASME SA182)

2. Cladding Material & Thickness

• Alloy: e.g., Inconel 625, Monel 400, 316L Stainless

• Clad Thickness: Nominal/minimum (e.g., 3.0mm nominal after machining)

• Bonding Method: Explosive bonding, roll bonding, or weld overlay

3. Flange Design & Dimensions

• Flange Type: Weld neck, slip-on, blind, etc.

• Size & Pressure Class: e.g., NPS 12", Class 300

• Face Type: RF (Raised Face), FF (Flat Face), RTJ (Ring-Type Joint)

4. Cladding Coverage Zones

• Required Areas: Full face (including bolting circle), bore, hub, backsid

5. Machining & Finishing

• Surface Finish: Ra value (e.g., 3.2 μm for gasket seating)

• Final Dimensions: Post-clad machining allowances (clad layer shrinks during bonding)
