About Sms Union

SMS union offered by DPL refers to a type of hygienic pipe fitting commonly used in industries like food processing, pharmaceuticals, and biotechnology. The term SMS stands for Swedish Manufacturing Standard, which defines the design and dimensions of these fittings.

Key Features of SMS Unions

Components: Typically include a union nut, welding male, welding liner, and a gasket.

Design:

Crevice-free and smooth internal bore for hygienic flow.

Round slotted nut and square section joint ring for secure sealing.

Materials: Usually made from stainless steel grades like SS 304, 316, or 316L.

Seal Types: Common gasket materials include EPDM, PTFE, Silicone, and Buna-N.

Sizes: Available in sizes ranging from 1 to 4.

Applications

SMS unions are widely used in:

Food and beverage production

Dairy and brewery systems

Pharmaceutical and biotech industries

Chemical and petrochemical plants

Their hygienic design makes them ideal for systems requiring frequent cleaning or sterile conditions, and they allow easy disassembly without disturbing adjacent piping.

Versatile and Hygienic Design

With its round shape, forged technique, and polished finish, the SMS Union is tailored for industries demanding stringent hygiene standards. Its exceptional corrosion resistance makes it especially valuable in processes requiring prolonged contact with chemicals or dairy products. Connections are available in tri-clamp, threaded, or butt weld ends, providing flexibility for new setups or system upgrades.

Customizable Fit and Strength

Offered in a range of sizes from 1/2 inch to 4 inch with wall thicknesses between 1.2 mm to 3 mm, SMS Union can be tailored to specific application requirements. The use of high-grade stainless steel (304/316L) ensures both mechanical strength and longevity, making the union suitable for demanding environments. Its high tensile strength of 550 MPa supports robust industrial operations.

FAQs of Sms Union:

Q: How is the SMS Union installed in processing lines?

A: SMS Union can be installed using tri-clamp, threaded, or butt weld connections depending on the system configuration. Tri-clamp unions offer quick assembly and disassembly, while threaded and butt weld options provide secure, leak-proof joints ideal for high-pressure or permanent installations.

Q: What industries benefit most from using SMS Union?

A: This product is primarily used in dairy, pharmaceutical, and food & beverage processes where hygiene, corrosion resistance, and robust pressure handling are essential. Its stainless steel construction ensures compliance with industry safety regulations and sanitary requirements.

Q: When should I select grade 304 versus 316L for my SMS Union?

A: Grade 304 is suitable for general purposes with moderate corrosion risk, while 316L provides enhanced resistance to chemicals and chlorides. Opt for 316L in pharmaceutical and saline-rich environments for longer durability.

Q: Where is SMS Union typically used within a system?

A: SMS Unions are commonly installed at pipe or tube intersections, allowing easy disconnection for cleaning, inspection, or maintenance in pipelines that transport dairy, food, beverages, or pharmaceutical products.

Q: What is the process involved in manufacturing SMS Union?

A: SMS Unions are manufactured through a forging process followed by precision machining and surface polishing to meet SMS 1145 standards. Each unit undergoes strict quality checks to ensure uniformity, tensile strength, and hygienic finishes.

Q: How does the excellent corrosion resistance benefit my operations?

A: High corrosion resistance reduces equipment downtime due to leaks or contamination, prolongs the unions lifespan, and maintains the purity of transported substances, especially in critical sanitary applications.

Q: What packaging options are available for SMS Union shipments?

A: Shipping is available in sturdy corrugated boxes for standard protection or wooden cases for added safety during transit, especially for bulk orders or international exports.
