ISOflange

ISOflange is a term that refers to a type of flange connection standardized by the International Organization for Standardization (ISO). These flanges are designed to ensure interchangeability and compatibility between components manufactured by different companies, adhering to specific international standards. The primary purpose of ISO standards for flanges is to facilitate reliable and secure joining of pipes, valves, and other equipment in various industrial applications, including chemical processing, oil and gas, and power generation.

ISO flanges are characterized by their dimensions, pressure ratings, and material specifications, which are clearly defined in the relevant ISO standards. Common ISO flange standards include those for pipe flanges, such as ISO 7005 series, which covers a range of flange types like weld-neck, slip-on, blind, and threaded flanges. These standards dictate critical features like bolt hole patterns, flange face types (e.g., raised face, flat face), and the overall geometry of the flange to ensure a proper seal when used with mating components. The adherence to ISO standards promotes safety, efficiency, and ease of maintenance in systems where these flanges are employed.
