Product Detail

Product Tags

Hastelloy B3 is a nickel-chromium-molybdenum-tungsten alloy with excellent resistance to corrosion in both oxidizing and reducing environments. It offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. Hastelloy B3fittings are commonly used in applications where resistance to corrosion and high-temperature strength are required, such as in chemical processing, pollution control, and pulp and paper production.

Here are some common types of fittings made from Hastelloy B3:

1. Hastelloy B3 Butt-Weld Fittings: Butt-weld fittings made from Hastelloy B3 are designed for welding to connect pipes or sections of piping. They come in different forms such as elbows, tees, reducers, and caps, allowing for changes in pipe direction, diameter, or branch connections.
2. Hastelloy B3 Socket Weld Fittings: Socket weld fittings made from Hastelloy B2 are used for smaller pipe sizes. They feature a socket or recess into which the pipe is inserted and are welded around the pipe perimeter to create a strong and leak-free joint. Socket weld fittings include elbows, tees, couplings, and unions.
3. Hastelloy B3 Threaded Fittings: Threaded fittings made from Hastelloy B3 have internal or external threads that allow for easy installation onto pipes or other fittings without welding. They are commonly used for low-pressure applications and smaller pipe sizes. Threaded fittings include elbows, tees, unions, and couplings.
4. Hastelloy B3 Flanges: Flanges made from Hastelloy B3 are used to connect pipes or fittings, typically with bolts, creating a secure and leak-free joint. They are available in various types such as slip-on, weld neck, blind, and socket weld flanges. Hastelloy B3 flanges are used for joining pipes or attaching valves and other equipment to the piping system.
