Black Painted Carbon Steel Flange

This black painted slip-on raised face flange is a robust piping connection component, primarily crafted from carbon steel and finished with a protective black paint coating to resist corrosion and rust in general-purpose environments.

Its slip-on design allows the flange to slide directly over the end of a pipe, which is then secured by fillet welding at both the inner and outer edges for a stable, pressure-resistant bond. The raised face on its sealing surface, when paired with a compatible gasket, creates a tight, leak-proof seal suitable for low to medium pressure fluid systems, including water supply, HVAC, and industrial process piping.

The pre-drilled bolt holes ensure precise alignment with mating flanges, enabling quick and straightforward installation. The black paint coating provides an extra layer of protection against moisture and minor chemical exposure, extending the flange’s service life in indoor and outdoor applications. This type of flange is a cost-effective choice for projects where reliable performance and ease of assembly are priorities.
