Sanitary SMS union is a widely used type of sanitary fitting, mostly employed in pharmaceutical, food, and beverage industries. This union type offers hygienic sealing and is easily dismantled, making it an ideal sanitary connection for cleaning and maintenance purposes. In this article, we will be discussing 10 things you need to know about sanitary SMS union.
1. What is a Sanitary SMS Union?
A Sanitary SMS (Short for Swedish Metric Standard) Union is a type of coupling used to join two pipes in a hygienic process system. It is designed to connect the system without crevices or spaces where bacteria can grow, ensuring that the system remains sterile and uncontaminated.
2. Types of Sanitary SMS Union.
There are two types of SMS unions, namely the threaded or ‘male’ SMS union and the slip-on or ‘female’ SMS union. Threaded SMS unions require a threaded pipe connection, whereas slip-on SMS unions slide over a pipe end and are secured with a clamp.
3. SMS Union Sizes.
Sanitary SMS unions are available in a range of sizes from 12.7mm (½ inch) to 101.6mm (4 inches), making them suitable for a variety of process systems.
4. Materials Used.
SMS unions are constructed from a range of materials, including stainless steel, brass, and PVC, depending on the application. Stainless steel SMS unions are the most common type used in pharmaceutical, food and beverage industries, due to their corrosion resistance and durability.
5. Ease of Dismantling.
One of the key benefits of sanitary SMS unions is their ability to be easily dismantled. This feature allows for easy cleaning and maintenance of the system, making them a hygienic solution for use in industries where cleanliness is critical.
6. Compatibility.
SMS unions are compatible with a wide range of sanitary fittings, including Tri-Clamp and DIN union types. This compatibility allows for easy integration into the process system and simplifies the installation process.
7. Sealing Principles.
Sanitary SMS unions employ a gasket seal, which ensures a leak-proof connection between two pipes. The tightness of the seal is dependent on the pressure exerted by the clamp holding the union together.
8. Pressure Ratings.
Sanitary SMS unions are rated to handle different pressures depending on the material and size. Stainless steel SMS unions can handle pressures up to 10 bar, making them suitable for use in high-pressure process systems.
9. Quality Standards.
The quality of sanitary SMS unions is critical in ensuring that the process system remains hygienic. These unions adhere to strict quality standards, such as ASTM A270 and ASME BPE standards, ensuring that they meet the required hygienic standards.
10. Applications.
Sanitary SMS unions find widespread application in hygienic process systems found in pharmaceutical, food and beverage, and biotechnology industries, where maintaining a sterile environment is of utmost importance.
In conclusion, the use of sanitary SMS unions in hygienic process systems ensures that the process remains free from contamination and easy to maintain. These unions are readily available in a range of sizes, materials, and pressure ratings, making them a versatile solution for use in various applications. With strict adherence to quality standards, sanitary SMS unions are a reliable and trusted component in critical process systems.
