Designed for High-Pressure and Corrosive Environments
ASTM A182 F51 duplex stainless steel offers an excellent balance of high mechanical strength and superior corrosion resistance, making it ideal for offshore platforms, oil & gas pipelines, chemical processing units, and marine environments. The material’s compliance with NACE MR0175 ensures safe performance in sour service conditions containing hydrogen sulfide (H₂S).
The reducing threaded flange design allows seamless transition between different pipe sizes while maintaining a secure threaded connection, especially suitable for systems where welding is not preferred or space is limited.
