ISO 65 Carbon Steel Tube

china spiral welded pipe manufacturer and supplier

ISO 65 Carbon Steel Pipe

ISO 65 refers to the standard for carbon steel pipe suitable for threaded connections, specifically designed to comply with ISO 7-1, which outlines the requirements for pipe threads. Suitable for tightening, ISO 65 carbon steel pipe is widely used in the pipeline and construction sectors, where reliable connections are required.

We offer ISO 65 carbon steel pipes, sizes DN 6 to DN 150. They are available as seamless or welded, in heavy, medium, light 1, and light 2 series.

ISO 65 pipes come in many forms. They include galvanized pipes, which are coated to prevent corrosion. They also include black pipes, which are often used in gas lines.

We have a solution for every need. Our steel grades range from high-strength, hard steels for heavy uses, to tough, ductile steels for bending and forming.
