Our flanges are recognized for their exceptional corrosion resistance, excellent dimensional accuracy, superior mechanical strength, and long service life in demanding industrial applications.
UNS N02201 Nickel Alloy 201 is the low-carbon version of commercially pure Nickel 200. The reduced carbon content prevents graphitization during prolonged exposure to temperatures above 315°C, making Nickel Alloy 201 highly suitable for elevated-temperature applications. This alloy offers excellent resistance to caustic alkalis, reducing chemicals, neutral salts, distilled water, food-grade media, and various corrosive industrial environments. Because of these outstanding properties, Nickel Alloy 201 is extensively used in manufacturing industrial flanges for critical piping systems.
Slip-on SORF Flanges are one of the most widely used flange types because of their simple installation, cost-effectiveness, and excellent sealing capability. These flanges slide over the pipe before welding and are welded from both inside and outside to provide additional strength and leak-proof performance. Their ease of alignment and installation makes them an ideal choice for low- and medium-pressure industrial piping systems across multiple industries.
At Synergy Engineering Solution, every UNS N02201 Nickel Alloy 201 Slip-on SORF Flange is manufactured using advanced CNC machining technology, precision engineering equipment, and strict quality assurance procedures. Each flange undergoes comprehensive dimensional inspection, chemical analysis, mechanical testing, Positive Material Identification (PMI), and non-destructive testing before dispatch to ensure complete compliance with international quality standards.
UNS N02201 Nickel Alloy 201 Slip-on SORF Flanges are precision-manufactured pipe flanges designed to provide secure, leak-proof connections in industrial piping systems. These flanges are slipped over the pipe and fillet welded from both sides, providing excellent mechanical strength while simplifying installation and maintenance. Their design allows accurate pipe alignment and economical fabrication, making them one of the most preferred flange types for industrial projects worldwide.
Nickel Alloy 201 provides outstanding resistance to corrosion, oxidation, alkaline chemicals, and high-temperature service conditions. The alloy's excellent ductility, weldability, and toughness make these Slip-on Raised Face Flanges suitable for chemical processing plants, petrochemical facilities, offshore platforms, marine engineering, refineries, LNG terminals, desalination plants, food processing industries, pharmaceutical manufacturing, fertilizer plants, and power generation projects.
