What Is Class K9?<\/h2>\n

Class K9 is a wall-thickness class<\/strong> defined in the ISO 2531 standard for ductile iron pipes, where \u201cK\u201d classes categorize pipes by nominal wall thickness rather than by allowable pressure. The K9 designation specifies a particular series of nominal thicknesses that increase with pipe diameter, ensuring consistent mechanical and hydraulic performance across sizes.<\/p>\n
