Swivel Joints

ATN swivel joints are ball track controlled swivel elements with a medium channel, in order to ensure safe transport of liquids and gases. ATN swivel joints feature either 1 or 2 ball tracks, enabling swivel movements such as for example a 360° rotation without any problems, despite simultaneous external loading through force and torque.

ATN swivel joints are standardly produced in carbon steel (St52-3, 42CrMo4), stainless steel (1.4571), and also aluminium. Further stainless steels (1.4301, 1.4404) and materials such as Duplex, Superduplex and Hastelloy are available on request at all times.

Axial PTFE groove seal rings which are pretensioned with stainless steel springs are used as process seals. In special applications (e.g. FDA in the field of food and hygiene) particular compounds are used. All seals are extremely easy to replace, and available from stock as a seal kit.

The modular principle and 8 basic construction shapes mean that all spatial movements and connection parameters are possible without problems.

 

All ATN swivel joints up to a nominal width of DN1200 (48″) are manufactured completely at our plant in Herdecke. However, many types are available directly from stock, and welded models are available at short notice.
