Product Description

DIN11850 SMS Pipe Fittings Union Stainless Steel Union Fitting 

Our sanitary unions are engineered for secure pipeline connection, hygienic safety, and long-term reliability in fluid transfer and process control systems. Designed to meet strict sanitary standards, these unions ensure leak-free sealing, smooth flow transitions, and easy disassembly, making them ideal for food & beverage, dairy, pharmaceutical, biotechnology, brewing, water treatment, and chemical industries.

We provide a specialized range of hygienic union fittings to meet diverse pipeline requirements:

• Quick-Release Connection - Enables fast assembly and disassembly for cleaning, inspection, or maintenance.

• Precision Alignment - Ensures stable, tight sealing and reduces risk of leakage at pipe joints.

• Sanitary Construction - Mirror-polished, crevice-free surfaces prevent residue buildup and contamination.

Working Principle

The stainless steel sanitary union functions as a removable pipe joint, connecting two sections of pipeline through a threaded or clamp-based locking system. When assembled, the gasket provides a tight, hygienic seal; when disassembled, it allows rapid access for system maintenance, cleaning, or replacement without disturbing the rest of the line.

Specifications

• Size range: DN65 (other sizes available on request)

• Connection types: Tri-Clamp, Welded, Threaded, Flanged (DIN, ISO, SMS, 3A standards)

• Working pressure: Up to 10 bar

• Working temperature: -20°C ~ 200°C

• Surface finish: Mirror polished inside & outside, Ra ≤ 0.8μm

• Installation: Inline pipeline joints

• Applicable media: Food, beverages, dairy, biopharma, pure water, chemicals

Advantages

• OEM customization available for special projects

• ISO 9001, FDA, 3A, SGS compliant materials for global quality standards

• Leak-free hygienic sealing ensures pipeline integrity

• Tool-free maintenance with quick disassembly design

•  20+ years of export experience for reliable global cooperation
