A Subject to change without prior notice 8 March 2021 Food technique Since the company was founded, LINNEMANN has placed special value on plant construction with parts that are easy to clean for the food industry. Because special requirements are placed on components that are used in the field of food production, e.g.: the seals used are tested for compliance with the FDA regulations. Corresponding declarations of conformity ensure safety for users. Originally developed for the dairy industry, pipe screwed connections in accordance with DIN 11851 have since become standard in many areas of the food industry as well as the beverages and brewing industry. Clamp connections according to DIN 32676 for the food sector are also offered. The required pipes are manufactured according to DIN EN 10357 (formerly DIN 11850), and butt weld fittings according to DIN 11852. LINNEMANN stocks a comprehensive range of sizes in DIN, ASME and ISO dimensions, from DN1/4“ up to DN300, in order to connect to pipe diameters that are often different within plants. Clamp pipe connections DIN 32676, flange Ø 25 The clamp pipe connections with flange Ø 25 mm are TÜV certified and proved in Europe and Overseas since many years and are used especially with laboratory and production lines for liquid media. Preferential fields of application are research institutes, laboratories, bio-engineering, medical technology, food, beverage, pharmaceutical, cosmetics, and chemical industry. MINI-clamp connection: Clamp connections DIN-Norm 32676 with flange diameters 25 mm as well as 34 to 319 mm are used in plants in which liquid media or fine-grained bulk materials are processed. The mini-flanges are used especially in test systems in research areas and the larger flange diameters from Ø 25 mm are normal in industrial production processes. Typical fields are the food and beverage industry as well as dairies, breweries, wineries or in fruit juice production. The clamp connections are also used in water treatment plants and bulk materials systems in the chemical, pharmaceutical and cosmetic industries and in biotechnology. The gasket is inserted into the groove of a clamping ferrule in assembly. DIN, ISO and ASME clamping ferrules are available for this. The second clamping ferrule is placed against it and is therefore coaxially force-centred together with the gasket. The connection is positively locked with the clamping ring. If safety closures are required because of high pressure, protected clamps are available optionally.
