Advantages of A182 F316L Reducing Threaded Flange
Using a reducing threaded flange made from high-grade stainless steel provides several benefits for pipeline systems.
Excellent Corrosion Resistance
The ASTM A182 F316L material contains molybdenum, providing strong resistance to corrosion in chemical, marine, and industrial environments.
Flexible Pipeline Connection
A reducing threaded flange allows a transition from a larger flanged pipeline to a smaller threaded connection, simplifying pipeline installation.
Reliable Pressure Performance
With a Class 300 pressure rating, the reducing threaded flange ensures safe and stable operation in medium- to high-pressure piping systems.
Compliance with International Standards
Manufactured according to ASME B16.5, this reducing threaded flange meets widely recognized international engineering requirements.
Applications of Reducing Threaded Flanges
The reducing threaded flange supplied to the Indonesian customer is widely used in industries that require reliable and corrosion-resistant piping components.
Typical applications include:
- Oil and gas pipeline systems
- Chemical processing plants
- Offshore and marine engineering
- Water treatment facilities
- Industrial instrumentation connections
Because of their adaptability and corrosion resistance, A182 F316L reducing threaded flanges are commonly used in pipelines where flanged and threaded connections must be combined.
