EN 10374 - DIN 11852
The EN 10374 standard outlines the technical specifications for hygienic stainless steel welded fittings such as bends, tees, and adapters. These fittings are essential in process installations within the food and pharmaceutical industries. Production is based on the requirements set out in EN 10357, ensuring guaranteed quality and compatibility.
Other components, such as Y-pieces, crosses, or end caps, are not explicitly covered in EN 10374. However, these parts are manufactured from tube material that does fall under EN 10357. As a result, the dimensions and specifications of these products may vary by manufacturer, depending on their production process and design choices.
