UNS N02201 Nickel Alloy 201 Lapped Joint Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS N02201 Nickel Alloy 201 Lapped Joint Flanges in Mumbai.
Synergy Engineering Solution offers premium UNS N02201 (Nickel Alloy 201) lapped joint (lap-joint) flanges, which combine the benefits of highly ductile, low-carbon nickel with a removable backing flange design. Alloy 201 is a low-carbon variant of commercial nickel (often compared to Nickel 200) engineered for improved performance at elevated temperatures (above ~316 °C / 600 °F) where carbon effects may become limiting. Because of its excellent ductility, lower work hardening rate, good weldability, and robust corrosion resistance in many environments, Nickel 201 is well suited for critical piping systems that demand frequent disassembly, alignment flexibility, and high reliability.
As a manufacturer, stockist, and exporter, Synergy ensures that Nickel 201 lapped joint flanges are available in a wide range of sizes (from small bore to large diameters), pressure classes (ANSI/ASME classes 150, 300, 600, 900, 1500, etc.), and flange face types (raised face, ring joint, flat face, etc.). Their in-house forging, machining, inspection, and finishing facilities allow them to meet bespoke project specifications, including precise bore finishes, custom thicknesses, and tight tolerances. Because they also act as stockists, they maintain inventory buffers that help reduce lead times for clients — particularly for projects with urgent turnaround or replacement needs.
Synergy’s export footprint is broad: they export Nickel 201 lapped joint flanges to Oman, Qatar, Saudi Arabia, UAE, Kuwait in the Middle East, Spain and Germany in Europe, the USA and Canada in North America, and across various African markets and beyond. Their export services include certification (mill test certificates, third-party inspection when required), packaging for long-distance sea or air transport, customs support, and logistics coordination to ensure delivery reliability in international markets. Their experience with global clients helps them navigate regulatory compliance, import duties, and local project documentation requirements.
In performance terms, Nickel 201 (UNS N02201) provides a strong combination of corrosion resistance, ductility, and mechanical strength. Its chemical composition limits carbon to ~0.02 wt %, with impurities like Fe, Cu, Mn, Si below ~0.40–0.35 wt % and sulfur ≤ 0.01 %. This low carbon makes 201 more stable at elevated temperature than 200 in certain reducing or carburizing environments. In annealed condition, typical tensile strengths are ~345 MPa (50 ksi) or more, with yield strengths (0.2 % offset) in the ~70–100 MPa range, and elongation of ~40–50 % or higher in typical product forms. Its density is about 8.9 g/cm³, and its melting behavior is comparable to other pure nickel alloys (melting ~1,445 °C). Because of the low carbon, Alloy 201 is often chosen over 200 when the operating environment includes modest temperatures where carbon diffusion or carbides might otherwise degrade performance.
Types Of Flanges manufacturer
In marketing and technical communications, Synergy positions its Nickel 201 lapped joint flanges as ideal for industries such as chemical processing, petrochemical, desalination plants, pharmaceuticals, offshore and marine systems, and specialty process piping. The lapped joint configuration is beneficial in systems requiring frequent disassembly (for cleaning or inspection) or where flange alignment is a challenge, since the backing flange can be positioned independent of the stub end. Synergy’s commitment to global reach, technical support, and material traceability (heat numbers, certification, third-party validation) underscores its role as a reliable supplier to projects in the Middle East, Europe, North America, Africa, and beyond.
For procurement teams and project engineers seeking UNS N02200 lapped joint flanges, Synergy Engineering Solution positions itself as a reliable partner by combining manufacturing competence, ready stock, and global export experience. Whether you require a single custom-sized flange, bulk inventory for maintenance turnarounds, or ongoing supply agreements across multiple countries, Synergy can provide technical support, competitive pricing, and flexible shipping solutions. If you want, I can convert this into product page copy, an HTML section, or a short technical datasheet for quoting and marketing — tell me which format you prefer.

Frequently Asked Questions (FAQ)
Q: What is the main difference between Nickel 200 and Nickel 201?
Nickel 201 (UNS N02201) has a lower carbon content (≤0.02%) compared to Nickel 200, making it more suitable for higher temperature applications above 600°F (316°C).
Q: Why are lapped joint flanges preferred in some piping systems?
The backing flange can be rotated to align bolt holes, making installation and disassembly easier. They are especially useful in systems requiring frequent inspection or cleaning.
Q: What certifications are provided with Synergy’s flanges?
Synergy supplies Mill Test Certificates (EN 10204 3.1), third-party inspection reports, and full traceability documents for international projects.
