TUBE MANUFACTURER ETHEN
DEFENCE
For maximum safety in safety-critical applications.
CAPILLARY AND PRECISION TUBES FOR YOUR APPLICATION
With our capillary and precision tubes, we make a reliable contribution to resilience and industrial value creation in the defence sector. Our components are used wherever precision, durability and reliability are essential, for example in vehicle and armoured vehicle systems, radar, sensor and surveillance technologies, as well as in test and inspection equipment. Whether used as structurally relevant components, in hydraulic control systems or for precise cooling, our tubes withstand extreme vibrations, pressure and temperature fluctuations.
Our mission for more than 65 years
Our capillary and precision tubes are part of machinery and plant manufacturing processes throughout the world. They are used to pressurise, regulate and control in the fields of medical engineering, raw material extraction and energy generation. We feel at home in all areas of application where maximum precision and heavy-duty characteristics are required. Therefore we manufacture our products on precision machinery developed in-house. Therefore precision regarding diameters only starts with the decimal places. That is why we have been a paragon of quality for more than 65 years. The importance of our products for our customers’ value creation spurs on our team.
That makes us a partner whose products made in Germany guarantee reliability throughout the world. That keeps inspiring us to more and more new investments in machinery and our know-how to keep pushing the limits of what is possible in the manufacturing of capillary and precision tubes. We turn tubes into forward-looking technologies – piece by piece, metre by metre. We just can’t help it. After all, precision is our passion.
OUTER DIAMETERS OF 0.7 MM TO 19.05 MM FOR ALL MATERIALS
On in-house developed tubes drawing machines, to which all the experience of our manufacturing experts was contributed, we manufacture capillary and precision tubes with an extraordinary range of outside and inside diameters.
The ETHEN tolerance standard is +/- 0.05 mm for outside diameters and +/- 10% for wall thicknesses. Tolerances DIN EN ISO 1127 D4/T4. Narrower tolerance ranges on request.
LENGTHS UP TO 6,400 MM OR AS SHORT AS YOUR REQUIRED BY YOUR APPLICATION.
On our advanced cutting machines, we also cut your capillary and precision tubes to length accurately down to decimal places – ranging from the ETHEN ROHRE maximum length of 6,400 mm to sleeves of minimum length. A service we offer to customers who value our standard of quality for tubes not drawn in our works as well.
SLEEVES FROM 2 MM LENGTH AND A OUTER DIAMETER OF UP TO 19.05 MM
Based on our capillary and precision tubes manufactured in-house, sleeves are made within very narrow tolerances for diameter and length in the ETHEN manufacturing centre. The latter are made with absolute precision on our advanced automatic sawing machines. Thanks to the standard barrel finishing procedure, we can offer them with a low-burr finish. ETHEN ROHRE produces sleeves from all materials ranging from titanium to Hastelloy, nickel and stainless steel.
