Stainless Steel Sanitary Union

Stainless Steel Sanitary Union

Stainless crescent wrench unions are fittings used to ensure that pipelines can be disconnected in a practical way without being cut. Stainless Steel Sanitary Union are so named because they are loosened and tightened with a half-moon shaped wrench called a crescent wrench. Stainless crescent wrench fittings, which are generally used in the food industry, are provided with a sealing gasket and are produced from 304 and 316 quality stainless steel.

Stainless steel unions are designed for maintenance or replacement of pipes. They consist of three parts and make it possible to remove and install only the union parts without dismantling the pipes in the piping system. Stainless steel unions are available in three types: stainless threaded tapered unions, stainless welded unions, and stainless crescent key unions. Stainless crescent key unions are plumbing materials that are welded on both sides and are often used in the food industry. Crescent key fittings are fasteners that can be removed and installed with the crescent key on their names.

Stainless Sanitary Union

Stainless Steel Wrench Fittings are particularly preferred in areas where dismantling and reassembly of piping installations is required and where pipes can be easily cleaned. They can also be used in corrosive environments, for example in acid, chemical, salty and aqueous environments. As with other products in the hygienic products category, quality standards are determined by the quality certificates AISI304/304L, AISI316/316L, EN1.4307 and 1.4404.

Stainless steel keyed unions and stainless steel unions are important fittings for the maintenance and replacement of pipelines. They are used both in the food industry and in other industrial areas and stand out with their easy disassembly and assembly features.
