Greenline Pipe and Fitting is one of the most reputed manufactures, suppliers and exporters of fasteners. We also supply our products in the national and international markets. At Greenline Pipe and Fitting, we provide a complete range of duplex steel fasteners including Duplex 2507 Fasteners.
Super Duplex 2205 Fasteners are made of austenitic steel. These contain ferrite in it. Hence it has improved strength over other steel grades. This has high strength and effective resistance to pitting. It is resistant to stress corrosion cracking and fatigue. This makes it suitable for welding applications.
These have high molybdenum and chromium content in it. Therefore these offer unmatched corrosion resistances in its category. This makes these suitable for highly acidic industrial workflows. Workflows that make use of acetic and formic acid find these useful. They offer the best in class resistance to corrosion due to inorganic acids, particularly chlorides.
Some of these fasteners have thread inside. And this is why they are known as threaded Super Duplex fasteners. These get fit with the matching male thread in the pipe. These fasteners are sturdy and speedy. These fasteners are meant for moderate applications wherein there is controlled pressure. These are very well used to transport air or water in it. These are quite similar to slip on in shape but it has threads in the bore. The perfect combination of robust mechanical properties with balanced chemical composition makes is suited to many applications.
The unique composition provides great mechanical strength to the fasteners. The steel finish it comes with makes its appearance desirable. These fasteners have less amount of nickel that makes these more cost-effective in comparison to its competitors. This gives value for money to its end users.
Super Duplex 2205 Fasteners are in use in Oil industry equipment, to transport gas substance and in heat exchangers. The firefighting systems, Chemical process industries, and piping industries are also making use of these SS fittings. Apart from these desalination plants, high-pressure RO plants and seawater piping, Mechanical and structural components are the places where this super deluxe fitting finds its usage.
