From a humble beginning in 1980, Neo Impex Stainless Pvt. Ltd. has multiplied in its size, emerging as global manufacturers of Duplex S31083 / S32205 Flanges through the web of our in-house production centre fabricating flanges in rare metal types. We have a long procedure of quality control, under which we carefully assess all our products on the basis of various parameters. We test and verify the accuracy and precision of our Duplex Steel UNS S31803 Blind Flanges, qualifying fit enough to work as water-proof seals to pipe ends. They are resistant to general corrosion. We are suppliers of ASME SA182 Duplex Steel UNS S32205 Weld Neck Flanges to sea water and power generation equipment as their smooth surfaces can endure a temperature up to 600 ° F besides promoting excellent flow characteristics.
We have been ushering new stratagems to be quicker in delivering consignments. As exporters, our Duplex Steel DIN 1.4410 Socket Weld Flanges are competent to convey gases up to 600 psi, packaged and shipped to the nearest port for your convenience. A coordination between our production and sales team garner us to supply worldwide. Also We offer wide range of Duplex Steel ASTM A182 Flanges such as Duplex 2205 Slip On Flanges, Duplex Steel S31803 Weld Neck Flanges, Duplex F51 Socket Weld Flanges, Gr.

What are Duplex Steel S31803 Flanges?
Duplex Steel S31803 Flanges are flange fittings made from duplex stainless steel grade S31803. Duplex stainless steel offers excellent corrosion resistance and high strength, making it suitable for various industrial applications. S31803 flanges are commonly used in industries such as oil and gas, chemical processing, and offshore installations, where resistance to corrosion & mechanical strength are critical.
What is Duplex Steel S32205 Flange used for?
Duplex Steel S32205 Flange is specifically used for applications with higher corrosion resistance than S31803. S32205 is a duplex stainless steel grade with improved pitting and crevice corrosion resistance. These flanges are commonly used in environments containing chloride ions, such as seawater applications, desalination plants, and chemical processing plants.
What are the advantages of Duplex Steel 2205 Flanges?
The advantages of Duplex Steel 2205 Flanges include superior corrosion resistance, especially in harsh environments with high chloride content. They offer high strength and excellent toughness, allowing them to withstand extreme temperatures and pressures. Duplex Steel 2205 Flanges also provide good weldability & formability, making them easy to work with during installation. Their combination of properties makes them ideal for demanding applications, ensuring reliable & long lasting performance.
