ASTM A312 Carbon/Galvanized/Seamless Steel Pipe

1.PRODUCT DESCRIPTIONGalvanized Steel PipeGalvanized steel pipes are dipped into a protective zinc coating to protect the pipes from corrosion in wet environments. In addition, galvanized pipes are a lower cost alternative to  steel to achieve rust free protection for up to 30 years, while maintaining comparable strength with a durable surface coating.Galvanized Steel Pipe ApplicationsGalvanized steel pipe is used in numerous types of industrial applications, including:· General fabrication· Manufacturing· Repairs· Frames· Trailers· And moreGalvanized Steel Pipe vs. Black Steel PipeGalvanized steel pipe features a protective zinc coating that helps prevent corrosion, rust, and the buildup of mineral deposits, thereby extending the pipe's lifespan. Galvanized steel pipe is most commonly used in plumbing and other water-supply applications.Black steel pipe features an all-over black finish. It is commonly used in fire sprinkler systems thanks to its high heat resistance. Black steel pipe is also popular for other water transfer applications, including potable water, as well as in gas lines.Galvanized steel pipeWelding MethodERW for galvanized steel pipeApplicationStructural, Constructions, Machinery etcGradescarbon steel Q235, Q345, SS400, SS490, ST37.
