KIRAN PIPE FITTING & MANUFACTURING COMPANY. is a renowned fabricator and distributor of superior quality Duplex S31803/S32205 Pipe Fittings. Duplex 31803/32205 Pipe Fittings deliver high resistance to crevice corrosion and chloride corrosion. This resistance is extraordinarily vital for services like saltwater, control system water systems, marine environments, and a few food process applications.
The Duplex derives mixed microstructure containing equal portions of austenite and ferrite. The Ferritic alloy provides resistance to stress corrosion cracking and austenitic alloy offers ease of fabrication and corrosion resistance. These Pipe fittings work efficiently under both reducing and oxidizing conditions in acids and as a material of construction in gas desulphurization units. The higher nitrogen content guarantees excellent corrosion resistance.
KIRAN PIPE FITTING & MANUFACTURING COMPANY. ensures to use a premium quality raw material to design and develop Duplex Steel 2205 Pipe Fittings which ideally suits for high pressure and high corrosive environments. They are available in customized design and specifications suitable for the requirements of our clients. We fabricate premium Duplex 31803/32205 Pipe Fittings having numerous key features such as high resistance to corrosion fatigue, stress corrosion cracking especially chloride stress corrosion cracking, erosion, excellent workability and weldability.
KIRAN PIPE FITTING & MANUFACTURING COMPANY. has manufacturing unit with contemporary technology and machinery to assemble high-quality products. Our experienced professionals continuously acquire new skills and use their knowledge to enhance the quality of the products. Duplex 31803/32205 Pipe Fittings offer high resistance and strength to the crevice and pitting to erosion. They have improved thermal stability which minimizes the problems associated with the fabrication of components.
