    Ductile Iron Pipe Markings: What Do They Mean?

    By Jeff Houser   07/24/2018  In Products Technical What is

    All Ductile iron pipe manufacturers use similar markings to help customers select the right material for the project. This includes verifying the material is suitable for the intended application (i.e., water or sewer) and meeting project requirements stipulated by the owner/engineer for pipe class, lining, and exterior coating. 

    Because each manufacturer's colors may vary, we will explain how McWane Ductile applies these markings and describe their purpose and locations.
