Complete Range of Waspaloy Pipe Fittings, Flanges & Branch Olets – Compliant with ASME B16.5, B16.11, MSS SP-97 – Global Stock Ready to Ship.
We are an ISO 9001:2015 certified supplier and exporter of high-performance nickel-based alloys including Waspaloy (UNS N07001), known for its outstanding mechanical strength and oxidation resistance at elevated temperatures. Our product portfolio includes a complete range of Waspaloy buttweld fittings, forged flanges (WNRF, SORF, Blind), socket weld/threaded forged fittings, and MSS SP-97 compliant olets – all manufactured as per ASME B16.5, B16.9, B16.11 & international standards. We ensure timely global delivery to industries requiring critical alloy solutions.
Waspaloy offers exceptional high-temperature strength, creep resistance, and excellent corrosion resistance in oxidizing environments up to 870°C (1600°F). Its age-hardenable nickel-based chemistry makes it ideal for high-stress structural applications. Our fittings and flanges in Waspaloy provide superior fatigue performance, thermal stability, and resistance to stress corrosion cracking – making them suitable for aerospace, turbine engines, nuclear reactors, and chemical processing systems.
Waspaloy fittings, flanges, and olets are widely used in sectors where high mechanical strength and thermal fatigue resistance are crucial – such as jet engine parts, gas turbines, combustion chambers, afterburners, pressure vessels, and petrochemical heat exchangers. We supply components customized for high-pressure systems, aggressive chemical environments, and applications demanding exceptional durability under fluctuating thermal loads.
Waspaloy (UNS N07001) is primarily composed of Nickel, Chromium, and Cobalt with trace additions of Aluminum and Titanium for age hardening. It conforms to ASTM B637 and is available in forged, machined, or fabricated forms. Mechanical properties include a tensile strength exceeding 100 ksi (690 MPa), high yield strength, and excellent elongation. All products undergo rigorous testing – including PMI, UT, hardness, hydrostatic, and radiography – and are supplied with EN 10204 3.1/3.2 certification, ensuring full traceability and compliance.
