Black Paint Flanges are a key component widely used in industrial piping systems and equipment connections.

1. Appearance and Materials

Appearance

As the name suggests, they are coated with black paint. This black appearance not only gives the flange a simple and calming visual effect, but the black paint also provides protection and identification.

Material

Flanges are typically made of metal, such as carbon steel or stainless steel. Black Paint Flanges made of carbon steel offer excellent strength and toughness, capable of withstanding high pressures. They are suitable for connecting common industrial pipes with high strength requirements, such as water supply and drainage pipes and heating pipes. Black Paint Flanges made of stainless steel offer improved corrosion resistance and excel in pipe connections in industries such as chemical and food processing, where hygiene and corrosion resistance are paramount.

2. Functional Features

Connection Function

The main function of a Black Paint Flange is to connect pipes or equipment. Using bolts, nuts, and other fasteners, it securely connects two pipes or a pipe to equipment. Its design ensures a strong seal, effectively preventing leakage of fluids within the pipes.

Sealing Performance

The precision-machined flange connection surfaces, combined with high-quality sealing gaskets, ensure a secure seal under varying pressures and temperatures. Black Paint Flanges prevent steam leakage in high-temperature environments, such as steam piping systems in thermal power plants, and operate reliably in high-pressure environments, such as those in petrochemical transmission pipelines.

Protection and Identification

The black paint coating not only serves a decorative purpose but also protects the flange's metal material from environmental aggressors, such as rust and chemical corrosion. Furthermore, the black appearance helps identify and distinguish piping systems in complex industrial environments, facilitating maintenance and management.

With its unique appearance, reliable connection, and sealing performance, Black Paint Flanges play an irreplaceable role in numerous industrial fields.
