The SMS 1145 couplings
The SMS 1145 standard is a specification developed specifically for hygienic piping components and connections used in the food and pharmaceutical industries. Originating from Sweden, this standard is internationally recognized, particularly in environments that require a high degree of cleanability and reliability. SMS 1145 connections are designed for easy disassembly, which is crucial for processes that involve regular cleaning and inspection.
What sets the SMS 1145 standard apart is the combination of a smooth internal surface, a solid seal and simple assembly. This minimizes the risk of product residues and microbial contamination. As a result, this standard is highly suitable for installations where hygiene, process reliability and traceability are key. In addition, the uniform dimensions and tolerances ensure seamless integration with other standardized components. At SKS, we supply these connections in high-quality SS 304 / 304L and SS 316 / 316L.
