Black steel pipe made from low-carbon steel, which is strong and durable. The pipe has a dark color due to the iron oxide formed during the manufacturing process. Unlike galvanized steel, black steel pipe does not have a zinc coating. The black color comes from the iron oxide that forms during the heat treatment process. Black steel pipes from black pipe fittings manufacturer JIANZHI are vailable in various sizes and wall thicknesses to accommodate different applications and pressure requirements.
Manufacturing Process of Black Steel Pipe
- Forming: The steel is heated and stretched to form a pipe.
- Heat Treatment: The pipe is treated with high heat, which forms a dark iron oxide layer on the surface, giving it its distinctive black color.
