Incoloy 825 threaded fittings are corrosion-resistant alloy components designed for use in high-stress and chemically aggressive environments. Manufactured from a nickel-iron-chromium alloy with molybdenum, copper, and titanium, these fittings offer excellent resistance to acid attack, pitting, and chloride-induced corrosion. Threaded fittings are commonly used in low-pressure pipelines, chemical injection systems, offshore platforms, and marine installations. This article introduces the types of Incoloy 825 threaded fittings, key manufacturers, and their certifications.
Types of Incoloy 825 Threaded Fittings
Threaded fittings come in various shapes and sizes to support pipe connections, direction changes, and terminations.
Fitting Type | Description | Thread Standard |
---|---|---|
Threaded Elbow (45° / 90°) | Changes direction of flow | NPT / BSPT / BSPP |
Threaded Tee | Branches flow into two directions | NPT / BSP |
Threaded Coupling / Half Coupling | Connects two male threaded pipes | NPT |
Threaded Plug / Cap | Closes end of threaded pipe | NPT / BSP |
Threaded Union | Allows disconnection of pipelines | NPT / BSP |

FAQs About Incoloy 825 Threaded Fittings Manufacturers
Do manufacturers offer both NPT and BSP thread types?
Yes, most Incoloy 825 fitting manufacturers support both NPT (American) and BSP (British) thread standards upon request.
Can Incoloy 825 fittings be used in high-pressure systems?
Threaded fittings are suitable for low- to medium-pressure applications; for high-pressure use, socket weld or butt weld fittings are preferred.
Are MTC and third-party inspections available?
Reputable manufacturers provide Mill Test Certificates and offer third-party inspections (like SGS or BV) as per customer requirements.
