DIN11864 defines stainless steel aseptic connection systems for hygienic and sterile process piping. The standard family covers different joint designs, while DIN 11864-2 focuses on flange connections using an O-ring and welded pipe interface. This structure is suited to process lines where cleanability, sealing integrity and controlled internal geometry are required.
How DIN11864 parts differ
The DIN11864 family is divided according to connection type. DIN 11864-1 covers screwed pipe connections, DIN 11864-2 covers flange connections, and DIN 11864-3 covers clamp connections. This distinction matters when replacing a fitting because the three connection systems are not interchangeable simply because they share the same nominal pipe size.
A search for din 11864 1 form a generally refers to the aseptic screwed connection design with an O-ring sealing arrangement. The flange version follows the same aseptic principle but uses a dedicated flange interface.
Why DIN 11864-2 uses a liner flange
The DIN 11864-2 liner flange creates a compact welded connection between the process tube and the flange component. An O-ring is positioned within the sealing geometry so that the joint can maintain a controlled seal with reduced dead space. Proper tube alignment and clean sealing surfaces are essential for reliable operation.
The stainless steel construction is suited to sanitary process environments where corrosion resistance and surface quality matter. The product specification identifies SS316L construction, flange-weld connection, a 0–10 bar working-pressure range and sizes from DN11 to DN100.
| Selection factor | What should be checked |
|---|---|
| Connection type | Flange, screw or clamp arrangement |
| Tube compatibility | Tube dimensions and welding requirements |
| Seal | O-ring material and dimensional fit |
| Surface condition | Internal finish and cleanability |
| Process conditions | Pressure, temperature and process medium |
DIN 11864-3 Form A and system selection
The phrase din 11864 3 form a refers to the clamp-connection section of the DIN11864 family. It is useful when a removable aseptic joint is preferred, while the DIN 11864-2 flange design is more suited to a bolted flange connection.
Selecting the correct DIN11864 component requires more than matching DN size. The connection type, tube standard, sealing profile, material and process conditions should all correspond. For an aseptic line, that complete match provides a sound basis for welding, sealing, cleaning and future maintenance.
