Nickel 200 Flanges Exporter In India
Comprehensive Technical Export Guide to UNS N02200 / W.Nr. 2.4066 Nickel 200 Weld Neck, Slip-On, Blind, Socket Weld, Threaded & Lap Joint Flanges Manufactured by Arrow Piping India
Complete Metallurgical & Export Specification Guide for Nickel 200 Flanges (UNS N02200 Pure Nickel Flanges) Exported Worldwide by Arrow Piping
Sourcing high-performance, precision-forged high nickel alloy flange components requires partnering with a certified and experienced Nickel 200 Flanges Exporter In India. In critical processing environments—ranging from caustic soda evaporation plants and synthetic fiber production to halide processing and food handling—standard stainless steel flanges such as 316L or duplex alloys frequently suffer from caustic stress corrosion cracking or localized attack under concentrated alkaline conditions. Nickel 200 (UNS N02200 / W.Nr. 2.4066 / ASTM B564) represents commercially pure wrought nickel metallurgy. Engineered with a minimum 99.0% Nickel composition, Nickel 200 offers unmatched resistance to caustic alkalis and a broad spectrum of reducing chemicals.
As a leading manufacturer, stockist, and Nickel 200 Flanges Exporter In India, Arrow Piping specializes in supplying high-precision metric and imperial flanges designed to handle extreme operational pressures and highly corrosive caustic media. Operating from Mumbai, Maharashtra, we manufacture and export complete piping flange solutions—including weld neck, slip-on, blind, socket weld, threaded, lap joint, orifice, and custom CNC-machined forged flanges—to EPC contractors, stockists, and industrial clients across the GCC, Europe, Americas, and Asia-Pacific regions.
1. What Are Nickel 200 Flanges & Why Are They Essential?
Nickel 200 Flanges are critical mechanical connection components forged or machined from high-purity Nickel 200 forged stock or plate material. Unlike standard stainless steels, Nickel 200 is designed to maintain exceptional ductility, thermal conductivity, and ferromagnetic properties, providing superior performance in caustic environments.
The alloy contains minimum 99.0% Nickel along with controlled levels of iron, copper, manganese, silicon, and carbon. These intentional alloying limits impart extraordinary immunity to caustic alkalis across all concentrations and temperatures up to its limits, neutral and alkaline salt solutions, and dry halogens. When specified as Nickel Alloy 200 Flanges, these components deliver outstanding structural stability, preventing catastrophic leaks in high-risk piping networks.

5. Deep-Dive Comparison: Nickel 200 vs. Nickel 201 vs. Stainless Steel 316L
Selecting the correct flange alloy prevents severe corrosion failures in aggressive chemical handling operations. Here is a quick metallurgical evaluation:
1. Nickel 200 (UNS N02200 / 2.4066):
Commercially pure wrought nickel with min 99.0% Ni and maximum 0.15% carbon. Excellent resistance to all concentrations of caustic soda, anhydrous ammonia, and dry halogens at temperatures below 315°C (600°F).
2. Nickel 201 (UNS N02201 / 2.4061):
Low-carbon version of commercially pure nickel restricted to max 0.02% carbon. Specifically formulated for operating temperatures above 315°C (600°F) to avoid intergranular graphitization that can occur in Nickel 200.
3. Stainless Steel 316L (UNS S31603 / 1.4404):
Standard austenitic stainless steel with 17% Cr, 12% Ni, and 2.5% Mo. While economical for general service, 316L rapidly succumbs to caustic stress corrosion cracking and pitting when exposed to hot concentrated alkaline environments.

10. Weight Estimation & Shipping Weight Formula for Nickel 200 Flanges
To assist logistics managers and structural piping engineers in estimating freight tonnage, use the accurate mathematical formula below for Nickel 200 steel flanges:
Formula for Approximate Plate Flange Weight:
Weight (kg) = [ π × (OD² - ID²) × Thickness × Density ] / 4000000
Where:
- OD = Flange Outer Diameter in mm
- ID = Flange Inner Bore Diameter in mm
- Thickness = Flange Total Thickness in mm
- Density = 8.89 g/cm³ (0.00000889 kg/mm³)
Engineering Note: For Weld Neck Flanges, include additional mass allowances for hub taper and raised face height.
