A Complete Threaded Fittings Solution by Prime Steel Corporation: An In-Depth Q&A Guide
At Prime Steel Corporation, we specialize in delivering high-quality ASME B16.11 forged threaded fittings to industries across the globe. This comprehensive Q&A blog dives deep into the technical, material, dimensional, and application aspects of threaded fittings — making it a one-stop solution for engineers, procurement heads, and industry professionals.
What are Threaded Fittings and how do they work?
Threaded fittings are forged pipe fittings used to connect piping systems in low-pressure and non-critical applications. These fittings feature internal threads (female) or external threads (male) and are screwed together to form a leak-tight joint.
Key Features:
- Conforms to ASME B16.11 standards.
- Commonly used for ≤6000 PSI pressure ratings.
- Installation does not require welding.
- Ideal for small bore piping (NPS 1/8″ to 4″).
What are the different types of Threaded Fittings offered by Prime Steel Corporation?
We offer a complete range of ASME B16.11 forged threaded fittings, including:
- Threaded Elbow (90°, 45°)
- Threaded Tee (Equal, Reducing)
- Threaded Cross
- Threaded Coupling (Full, Half, Reducing)
- Threaded Union
- Threaded Cap
- Threaded Plug (Square/Hex Head)
- Threaded Bushing (Hex Head, Concentric)
