With a strong presence in cities like Mumbai, Delhi, Bengaluru, Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, Vadodara, Rajkot, Nagpur, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, Varanasi, Amritsar, Chandigarh, Mysuru, Udaipur, Jodhpur, Visakhapatnam, Coimbatore, Madurai, Kochi, Thiruvananthapuram, Mangalore, Nashik, Kolhapur, Chandrapur, Akola, Vilayat, Somnath, Dahej, Narmada, Ankleshwar, Navsari, Valsad, and Rajpipla, Riddhi Siddhi Impex ensures timely and efficient delivery of these fittings to meet diverse industrial needs..

Copper Nickel Threaded Cross fittings are primarily available in two alloys: Cu-Ni 90/10 and Cu-Ni 70/30. Cu-Ni 90/10, also known as C70600, comprises approximately 90% copper and 10% nickel, offering excellent resistance to seawater corrosion and biofouling. Cu-Ni 70/30, or C71500, contains 70% copper and 30% nickel, providing enhanced strength and further improved resistance to corrosion in harsh environments. These alloys conform to international standards such as ASTM B122 and ASME B16.11, ensuring high-quality manufacturing and performance..

These fittings are typically made from copper-nickel alloys such as Cu-Ni 70/30 or Cu-Ni 90/10. The combination of copper and nickel provides excellent corrosion resistance, especially in seawater, chemical plants, and marine applications, making them ideal for industrial and marine piping systems..

RThreaded Cross fittings feature four outlets connected at 90° angles, with standard threaded connections for easy installation without welding. The threading allows secure attachment to pipes and other fittings, facilitating maintenance and replacement..

Copper Nickel Threaded Cross fittings are widely used in desalination plants, heat exchangers, seawater cooling systems, marine pipelines, chemical industries, and power plants. Their high durability and resistance to biofouling make them suitable for both fresh and saltwater applications..
