Overview
Product overview
Forged Boss fittings are crucial components in piping systems, used to connect pipes of different sizes or change the direction of flow. At Fortune Fittings Private Limited, we specialize in manufacturing high-quality ASME B16.11 Boss fittings, both threaded and socket weld types, suitable for various industrial applications.
What is a Forged Boss Fitting?
ASME B16.11 Boss fittings are standardized by the American Society of Mechanical Engineers (ASME), ensuring uniformity in dimensions and specifications. These fittings are forged, a process involving heating and shaping metal using compressive force, resulting in superior strength and durability.
Types of Forged Boss Fittings
- Threaded (Screwed) Boss:Description: This type features threaded ends that can be screwed onto pipes or other fittings with compatible threads.
- Applications: Commonly used in low-pressure applications where ease of installation and removal is important.
- Socket Weld Boss:Description: This type has socket weld ends, allowing the boss to be welded directly to pipes or other fittings with compatible socket weld ends.
- Applications: Ideal for high-pressure applications requiring a strong and permanent connection.
Conclusion
Our dedication to quality, a wide range of material options, and adherence to international standards ensure that our forged Boss fittings meet the highest industrial requirements. Contact us today to learn more about our products and how we can fulfill your piping system needs.
