This welded reducer is used for smooth transitions between pipes of different diameters. Manufactured according to ISO/IDF international standards, it ensures high compatibility across different regional equipment. The optimized conical angle maintains stable flow velocity and reduces material impact or turbulence. The welded connection offers high strength, making it suitable for sanitary systems involving high-temperature cleaning and frequent operation. Widely used for pump inlet reduction, process line end closures, and connections between equipment of varying sizes, it is a commonly used basic transition component in international food production lines.
