Stainless Steel SMS Union – Neza

Technical Specifications: SS SMS Union

Introduction to Stainless Steel SMS Unions

Stainless steel SMS unions are critical components in sanitary piping systems where hygienic, leak-proof connections are essential. At Neza Engineering Co., our Neza brand SMS Unions are designed for precision, durability, and strict hygiene compliance. These unions are widely used in the dairy, food, beverage, pharmaceutical, and chemical industries.

Manufactured as per Swedish Standard SMS 1145, our SMS Unions ensure compatibility, easy assembly, and disassembly for cleaning and maintenance. The union consists of four key parts: the male part, liner (welding ferrule), nut, and gasket. Together, they form a tight and secure connection suitable for both static and dynamic applications.

Why Choose Stainless Steel SMS Unions?

Using stainless steel SMS Unions provides several benefits in process systems:

1. Hygienic Design: Smooth interior surface eliminates crevices where bacteria can grow.

2. Robust Construction: High-quality SS 304, 316, or 316L ensures corrosion resistance and strength.

3. Tool-Free Maintenance: SMS unions can be quickly opened and reassembled without special tools.

4. Versatility: Ideal for CIP (clean-in-place) and SIP (sterilization-in-place) applications.

5. Seal Integrity: High-grade elastomer gaskets maintain leak-proof operation even under pressure.

Components of Neza SMS Unions

Our SMS unions are manufactured with precise tolerances to ensure a perfect fit:

1. Male Part

• Welded to one end of the pipe.

• Machined to ensure accurate dimensions.

2. Liner (Welding Ferrule)

• Fitted to the adjoining pipe or valve.

• Designed to provide a smooth internal bore.

3. Nut

• Heavy-duty threading for secure tightening.

• CNC machined for durability and consistent grip.

4. Gasket

• Made of EPDM, Silicone, NBR, or Viton.
