Incoloy 330 / RA 330 / SS 330 Pipe Fittings & Flanges in All Types – Buttweld, Socket Weld, Threaded & Olets – ISO Approved | Worldwide Shipping.
We are a leading manufacturer and global exporter of Incoloy 330 (also known as SS 330 or RA 330) pipe fittings, flanges, forged fittings, and olets. These products are widely used in high-temperature industrial environments such as heat treatment, thermal processing, and petrochemical plants. Engineered for long service life under extreme thermal conditions, our RA 330 fittings and flanges are precision-made to ensure durability and compliance with international quality standards including ASME, ANSI, and ASTM.
We supply a full range of Incoloy 330 buttweld fittings including elbows, tees, reducers, and caps, as well as flanges such as weld neck, slip-on, blind, socket weld, and threaded flanges. Our forged fittings are available in Class 2000, 3000, and 6000, and include socket weld and threaded elbows, tees, unions, and couplings. In addition, we offer olets like weldolets, sockolets, and threadolets to meet complex piping layout requirements. These products are extensively used in heat treatment furnaces, petrochemical reformers, chemical processing plants, and industrial boilers.
All Incoloy 330 / SS 330 / RA 330 products undergo strict quality testing such as PMI (Positive Material Identification), ultrasonic testing, and mechanical property verification. Our manufacturing facilities are ISO 9001:2015 and PED certified, ensuring consistent quality and documentation. Fittings and flanges are packed securely in export-grade wooden crates with proper labeling and traceability. We export globally to markets in the USA, Europe, Middle East, and Southeast Asia, offering rapid delivery and customized documentation for EPC contractors, OEMs, and stockists.
