UNS N02201 Nickel Alloy 201 Lapped Joint Flanges are rotating flanges used with stub ends to simplify installation, maintenance, and alignment while providing excellent corrosion resistance and reliable sealing.
Synergy Engineering Solution is a leading manufacturer, stockist, supplier, and worldwide exporter of premium quality UNS N02201 Nickel Alloy 201 Lapped Joint Flanges. We manufacture high-performance lap joint flanges using premium-grade Nickel Alloy 201 that conforms to ASTM B564, ASME SB564, ASME B16.5, ASME B16.47, DIN, EN, ANSI, and other international standards. Our flanges are engineered for exceptional corrosion resistance, superior mechanical strength, excellent dimensional accuracy, and long-term performance in highly demanding industrial applications.
UNS N02201 Nickel Alloy 201 is the low-carbon version of commercially pure Nickel 200. The reduced carbon content minimizes graphite precipitation during prolonged exposure to temperatures above 315°C, making Nickel 201 highly suitable for elevated-temperature applications. This alloy provides outstanding resistance to caustic alkalis, neutral salts, organic chemicals, reducing acids, distilled water, and numerous corrosive industrial environments. Its excellent ductility, weldability, toughness, and oxidation resistance make it one of the most reliable materials for manufacturing industrial flanges.
Lapped Joint Flanges are specifically designed to be used with stub ends, allowing easy assembly, quick dismantling, and convenient alignment of bolt holes. Because the flange does not come into direct contact with the process fluid, it significantly reduces installation costs while providing excellent flexibility during maintenance, inspection, and piping modifications. These flanges are widely preferred for systems requiring frequent dismantling and inspection.
At Synergy Engineering Solution, every UNS N02201 Nickel Alloy 201 Lapped Joint Flange is manufactured using advanced forging technology, precision CNC machining, and rigorous quality control procedures. Each flange undergoes comprehensive testing, dimensional inspection, and material verification before dispatch to ensure complete compliance with international quality standards.
UNS N02201 Nickel Alloy 201 Lapped Joint Flanges are premium-quality pipe flanges designed for piping systems where frequent dismantling, maintenance, cleaning, and inspection are required. These flanges are installed together with stub ends, allowing the flange to rotate freely around the pipe for easy bolt alignment. This design reduces installation time while improving maintenance efficiency in industrial piping systems.
Nickel Alloy 201 provides exceptional corrosion resistance against caustic alkalis, reducing chemicals, food-grade media, pharmaceutical chemicals, marine environments, and numerous industrial fluids. The alloy's low carbon content makes it highly resistant to intergranular attack and suitable for prolonged service at elevated temperatures. As a result, Nickel Alloy 201 Lapped Joint Flanges are widely used in chemical processing plants, oil & gas industries, offshore platforms, refineries, marine engineering, fertilizer plants, LNG terminals, food processing facilities, pharmaceutical plants, desalination systems, and power generation projects.
Synergy Engineering Solution manufactures UNS N02201 Nickel Alloy 201 Lapped Joint Flanges in a complete range of pressure classes, sizes, facing types, and customized dimensions according to customer drawings and international specifications. Every flange is supplied with complete material traceability, EN 10204 3.1 Mill Test Certificates, inspection reports, and export-quality packaging for safe worldwide transportation.

Our manufacturing facility is equipped with advanced forging presses, CNC machining centers, automated drilling machines, precision calibration equipment, modern inspection laboratories, and quality assurance systems. These capabilities enable us to manufacture flanges with exceptional dimensional accuracy, superior surface finish, and consistent mechanical performance.
Each manufacturing stage—including raw material inspection, forging, machining, drilling, facing, finishing, marking, and final inspection—is carefully monitored by experienced engineers. Our products comply with ASTM, ASME, ANSI, DIN, EN, JIS, and BS standards, ensuring reliable performance in the world's most demanding industrial environments.
We also manufacture customized Lapped Joint Flanges according to customer drawings, pressure ratings, drilling standards, and special project specifications. Our engineering expertise allows us to support EPC contractors, OEM manufacturers, and industrial projects requiring tailor-made flange solutions.
In addition to manufacturing, Synergy Engineering Solution maintains one of India's extensive inventories of UNS N02201 Nickel Alloy 201 Lapped Joint Flanges. Our ready stock includes various sizes, pressure classes, and specifications, enabling us to fulfill urgent maintenance shutdowns, refinery expansions, EPC contracts, and industrial replacement requirements with minimal lead time.
As a globally recognized exporter, we supply premium-quality Nickel Alloy 201 Lapped Joint Flanges to customers across Asia, Europe, North America, South America, Africa, and Australia. Our strongest export market is the Middle East, where our flanges are widely used in oil & gas processing facilities, petrochemical plants, offshore platforms, LNG terminals, desalination projects, marine engineering, fertilizer plants, and power generation industries.
We regularly export our UNS N02201 Nickel Alloy 201 Lapped Joint Flanges to the United Arab Emirates (Dubai, Abu Dhabi, Sharjah), Saudi Arabia, Qatar, Oman, Kuwait, Bahrain, Iraq, Jordan, Egypt, and other GCC countries. Every shipment is supported with complete export documentation, third-party inspection certificates, Mill Test Certificates, and secure export-quality packaging to ensure safe and timely worldwide delivery.
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.
