Our flanges are designed to connect different sized pipes seamlessly, ensuring no restriction in product flow and minimizing turbulence and erosion at the joints.
As a leading ASTM A105 flange manufacturer offering products for your flange needs, with products that deliver superior performance and long-lasting reliability.
What is ASTM A105 Flange?
ASTM A105 flanges range from class 150 to 2500 and PN6 to PN64, with lower classes not needing heat treatment. Flanges above Class 300 may undergo annealing, normalizing, or quenching for sizes over 4 inches. They are weldable and meet ASME standards for pressure applications.
These carbon steel flanges connect pipes in high-temperature and high-pressure settings, meeting stringent industry standards. After normalization, ASTM A105n Blind Flanges offer superior performance in critical conditions. Welding neck flanges(A105 Wnrf Flanges) ensure secure pipe connections, while normalizing enhances their durability and strength.
