A Complete Guide to Sanitary Fittings & Unions

As the name suggests, sanitary fittings are crucial to any food processing or pharmaceutical plant. These fittings are used to maintain the purity of fluids that flow through the pipelines and prevent microbial contamination. Sanitary fittings are also required to ensure the efficient transfer of fluid by reducing turbulence and enhancing flow rate. On the other hand, sanitary unions connect different sections of a pipeline, allowing for easy assembly and disassembly. This blog post will explore the different types of Sanitary Fittings and Unions available and their applications in various industries.

What are Sanitary Fittings and Unions?

Sanitary fittings and unions are components used in the plumbing of bathrooms, kitchens, and other areas where sanitation is essential. They create a safe and reliable connection between pipes to ensure proper flow without contact with contaminants. Sanitary unions come in several sizes to accommodate all types of piping needs. Depending on the desired durability requirements, they can be made from stainless steel or brass. These components are designed for maximum performance even at extreme temperatures while supporting high-pressure water applications and low-pressure drainage systems. With reliable connections and excellent corrosion resistance properties, these fittings provide an effective long-term solution for any commercial or residential sanitary piping needs.

Understanding Sanitary Fittings and Unions

Types of Sanitary Fittings:

Sanitary fittings can be classified into three categories – threaded, clamped, and welded. Threaded fittings are screwed onto the pipeline, while clamped fittings use tri-clamp connections that use gaskets and clamps. Welded fittings, as the name suggests, are welded onto the pipeline. The fitting type choice depends on the project’s specific requirements and budget.

Applications of Sanitary Fittings: 

Sanitary fittings are widely used in the food, beverage, pharmaceutical, and cosmetics industries, where hygiene is paramount. Sanitary fittings are used in various applications, from dairy processing to chemical transfer. Some common applications of sanitary fittings include pipe fittings, valves, pumps, and expansion joints.

Types of Sanitary Unions: 

Sanitary unions, also known as pipe unions, connect two or more sections of a pipeline. There are three types of sanitary unions – threaded, clamped, and flanged. Threaded unions are screwed onto the pipeline, while clamped unions use gaskets and clamps. Flanged unions are bolted onto the pipeline and are used for high-pressure applications. Sanitary unions are essential components that allow for quick assembly and disassembly of pipelines.

Applications of Sanitary Unions: 

Sanitary unions are used in industries that require frequent assembly and disassembly of pipelines. From cleaning and maintenance to replacing worn-out components, sanitary unions play a crucial role in ensuring the smooth functioning of a pipeline. Sanitary unions are used in various applications, including dairy processing, brewing, pharmaceuticals, and cosmetics.

Considerations for Choosing Sanitary Fittings and Unions: 

When choosing sanitary fittings and unions, it is essential to consider the material of construction, pressure rating, temperature range, and compatibility with the fluid being transported. Stainless steel is the most commonly used material for sanitary fittings and unions due to its corrosion resistance and durability. The fitting’s pressure rating and temperature range should be matched with the specific application. Compatibility with the fluid being transported is also essential, as certain fluids can corrode or degrade the construction material.

Conclusion:

Sanitary fittings and unions play a crucial role in maintaining the purity of fluids and preventing microbial contamination in pharmaceutical and food processing plants. The type of fitting or union chosen depends on the specific requirements and budget of the project. Sanitary fittings and unions are essential components that allow for quick assembly and disassembly of pipelines, making them a critical factor in the smooth functioning of a plant. When choosing sanitary fittings and unions, it is essential to consider the material of construction, pressure rating, temperature range, and compatibility with the fluid being transported. Understanding the different types and applications of sanitary fittings and unions can ensure a safe and efficient fluid transfer in your plant.
