About Din Union

Din Union is a special structure which allows connection & disconnection without disturbing other piping arrangements. It is also admired for assuring tight & leak proof fitting and help in easy dismantling for cleaning purpose. This union is made of high grade steel alloy with zinc coated surface finish. It is chemically inert and finds application for food processing, pharmaceutical, & dairy industries. This union is said to be completely suitable for both high & low pressure conditions with superior reliability. Din Union is available at highly competitive rates in bulk & different dimensional configurations for our respected clients.

Versatile Applications Across Industries

The DIN Union is tailored for sectors where hygiene, reliability, and chemical resistance are essentialincluding dairy, food processing, beverages, pharmaceuticals, and chemicals. Its stainless steel construction and multiple sealing options ensure compatibility with a variety of fluids and cleaning regimes, making it a trusted solution for both new installations and retrofits.

Engineered for Durability and Performance

Constructed from forged SS304/SS316 with polished surfaces and conforming to DIN 11851, the unions provide exceptional mechanical strength (tensile strength up to 520 MPa) and high corrosion resistance. The union is designed for user convenience, offering male/female threaded, plain end, butt weld, or flanged options to suit different piping setups.

FAQs of Din Union:

Q: How is the DIN Union installed in piping systems?

A: The DIN Union can be installed using male or female threads, butt weld, or flanged connections. This flexibility allows easy integration into a range of piping layouts by simply matching the desired end connectionplain end or threaded endwith existing system requirements.

Q: What benefits does the DIN Union offer for hygienic industries?

A: With a polished stainless steel finish, chemical-resistant seals (EPDM, NBR, PTFE), and compliance with DIN 11851 standards, the DIN Union ensures contamination-free flow, durability, and quick disassembly for cleaning, making it ideal for dairy, beverage, and pharmaceutical applications.

Q: When should I choose EPDM, NBR, or PTFE sealing material?

A: Select EPDM for general food-grade applications, NBR for oil or fat resistance, and PTFE when demanding chemical resistance and higher temperature tolerance are required. The choice depends on your specific process fluids and operating conditions.

Q: Where are these DIN Unions typically used?

A: These unions are commonly utilized in production lines, transfer piping, and process equipment across the dairy, food, beverage, pharmaceutical, and chemical manufacturing industries, especially where frequent cleaning and hygienic operation are mandated.

Q: What is the process for selecting the correct DIN Union size and connection type?

A: To choose the right DIN Union, consider your systems inside diameter (1" to 4"), pressure (up to 16 Bar), temperature range (-20C to 180C), and required connection type (threaded, butt weld, flanged, plain end). Consulting process specifications ensures optimum fit and performance.

Q: How does the DIN Union ensure long-term corrosion resistance?

A: Manufactured with high-grade SS304 or SS316 stainless steel and a polished surface treatment, the DIN Union resists corrosion effectively, even under harsh process conditions, thereby extending service life and reducing maintenance.

Q: What packaging options are available when ordering DIN Unions?

A: To ensure safe delivery, DIN Unions are shipped in durable packagingusually carton boxes or wooden casestailored according to the size and quantity of items. This minimizes the risk of damage during transit.
