The full form of ISO in the context of ISO pipe is International Organization for Standardization.
The International Organization for Standardization (ISO) develops and publishes international standards. When we talk about "ISO pipe," we're generally referring to pipes and pipe threads that adhere to ISO standards, ensuring interchangeability and quality. This is particularly relevant for pipe threads used in plumbing, hydraulic, and pneumatic systems, among other applications. These standards define specifications like dimensions, tolerances, and materials.
For example, ISO has established metric pipe thread sizes used for screwing pipes together or into ISO pipe ports on components like valves, cylinders, and pumps. These standards help ensure compatibility across different manufacturers and regions.
