Manufacturer, Supplier & Exporter of Hastelloy B3 Ferrule Fittings

Hastelloy B3 Ferrule Fittings are engineered components designed for high-performance applications in aggressive chemical environments. Manufactured from a nickel-molybdenum alloy, Hastelloy B3 provides superior resistance to hydrochloric acid and other strong reducing agents. Riddhi Siddhi Impex, a well-known name in the metal industry, manufactures and supplies these fittings to meet the diverse needs of industries such as chemical processing, petrochemicals, pharmaceuticals, and power generation across India.

As a manufacturer and domestic supplier, Riddhi Siddhi Impex ensures that Hastelloy B3 ferrule fittings are produced with high precision and strict quality control. These fittings are widely used in fluid and gas transfer systems where resistance to corrosion, stress, and cracking is essential. The company offers a full range of ferrule fittings including unions, elbows, tees, bulkhead connectors, and adaptors, all manufactured to ASTM B619/B622 standards.

One of the key benefits of Hastelloy B3 over its predecessors (like B2) is its improved thermal stability and resistance to stress corrosion cracking and pitting. This makes it ideal for applications that involve variable temperatures and corrosive conditions. Riddhi Siddhi Impex ensures that all fittings undergo stringent testing and certification processes, including hydrostatic testing and dimensional accuracy verification.

These ferrule fittings are particularly important in process plants that handle concentrated hydrochloric acid, hydrogen chloride gas, and other reactive media. Their non-reactive nature ensures the purity of processed chemicals and extends the service life of the piping systems. The fittings are compatible with both seamless and welded tubing systems, offering flexibility for installation and maintenance.

Riddhi Siddhi Impex’s supply chain reaches all major Indian domestic cities such as Mumbai, Delhi, Bengaluru (Bangalore), Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, Surat, Vadodara, Rajkot, Indore, Bhopal, Jaipur, Kanpur, Lucknow, Agra, Varanasi, Amritsar, Chandigarh, Mysuru (Mysore), Udaipur, Jodhpur, Visakhapatnam, Coimbatore, Madurai, Kochi, Thiruvananthapuram, Mangalore, Nashik, Kolhapur, Chandrapur, Akola, Vilayat, Somnath, Dahej, Ankleshwar, Navsari, Valsad, Rajpipla and more. This allows for efficient product availability and timely delivery..
