At home in many industries.
Capillary and precision tubes from ETHEN ROHRE are used in all industries where a combination of delicate structural components and maximum quality is required. Whether for use in mass production or large facilities, in safety-critical or system-relevant applications, ETHEN ROHRE disposes of all certifications that officially acknowledge the necessary quality in writing as well. Furthermore customised advisory services and reliable logistics supplying worldwide make sure that you get the right tube delivered at the right time to the right place.
The largest customer industries of ETHEN ROHRE include:
ETHEN ROHRE for apparatus engineering
As far as apparatus construction is concerned, precise details are important. Especially when the dimensions get small and minute, there are demanding requirements regarding accurate manufacturing within narrow tolerance ranges. Capillary and precision tubes fulfil critical functions in many apparatuses and devices. With them the level of system quality as well as customers’ and users’ satisfaction increases or decreases. We offer you complete “capillary tube solutions” for your products, covering everything ranging from comprehensive technology and material advice to precise manufacturing monitored with end-to-end quality management and reliable logistics.
ETHEN tubes for the automotive industry
In the automotive industry, ETHEN tubes are used by external suppliers as well as car manufacturers. Before a component is approved by them for mass production, the components themselves and the producing company have to fulfil the comprehensive list of quality criteria.
ETHEN tubes for the chemical industry
In the chemical industry, it is a question of great resistance in sometimes aggressive environments, maximum precision for complex processes. Capillary and precision tubes from ETHEN function properly and durably inside the tube labyrinths of chemical plants. Operators of chemical plants are aware that safety on a large scale is only ensured by way of the most exacting quality criteria applied down to the most delicate components.
Precision and capillary tubes made from alloy B3/2.4600
ETHEN ROHRE produces customised precision and capillary tubes from the nickel-molybdenum alloy 2.4600 (alloy B3) with diameters from 1 to 19.05 mm for you. You can purchase B3 capillary tubes with the dimensions 8 x 1, 10 x 2 and 12 x 1 mm (outside diameter x wall thickness) from our distribution partner ZAPP Materials Engineering, for whom we exclusively manufactures tubes with these dimensions for stock.
The tubes made from the nickel-molybdenum alloy 2.4600 provide for very good resistance to aggressive and reducing media such as hydrochloric acid and sulphuric acid across wide concentration and temperature ranges. That makes it particularly suitable for use in the chemical industry and for users who want to use capillary and precision tubes in extreme environments.
The precision and capillary tubes were developed from B3/2.4600 in cooperation with ZAPP Materials Engineering. ZAPP Materials Engineering operates one of the largest service centres for special materials in Europe and closely cooperates as a Europe distributor with Haynes Int. Inc., Kokomo/USA. Haynes is one of the leading manufacturers of high-performance materials. Thanks to its melting and re-melt technology, the US-based company is able to adjust alloy contents such as chromium, molybdenum, cobalt, yttrium and titanium so precisely that extremely demanding material properties can be achieved as well.
“For an addition to our portfolio, we need a partner for the manufacturing of capillary tubes who can guarantee proper processing for standard alloys as well as for our original Hastelloy ® re-drawers with his experience and competence. We have found this partner in ETHEN ROHRE.”
Elmar Küpper, Robert Zapp Werkstofftechnik GmbH
Oil and gas industry
ETHEN tubes for the oil and gas industry
At least failing components in oil and gas supply systems cost a lot of money and in the worst case they destroy the environment with an effect lasting over years. For that reason, precision tubes do not only have to be manufactured with dimensional stability, but also have to be designed to maximum reliability in harsh environments. ETHEN tubes are among the finest structural parts on tankers, oil and gas platforms which ultimately ensure the stable, safe operation of the large systems.
ETHEN tubes for medical engineering
As regards medical devices, a diameter of a capillary tube that is a few millimetres too large or too little can result in misdiagnosis. For that reason, the manufacturers of medical devices thoroughly check their suppliers for the capacity to deliver components with absolute dimensional stability across many batches. The customers of ETHEN ROHRE comprise several of the largest companies in the German medical engineering industry.
Measurement and control technology
ETHEN ROHRE for measurement and control technology
High sensitivity, sensitive response to minimal changes and calibrated accuracy are the qualities demanded in measurement and control technology. For that reason system components have to be manufactured, especially with a view to small dimensions, in such a way that they are guaranteed to be free of defects and accurate – that also applies to precision and capillary tubes.
Quality-tested precision and capillary tubes manufactured within the narrowest of tolerance ranges for your measurement and control systems are offered to you by ETHEN ROHRE. They keep the promise that you give your customers.
“Measurement and control technology requires absolutely fail-safe systems. For that reason we have exclusively been using absolutely high-quality components in our products, among them also capillary tubes from ETHEN ROHRE.”
Duo Kohllöffel, Heinrichs Messtechnik GmbH
Energy and nuclear technology
ETHEN tubes for energy and nuclear technology
Power companies only allow exclusively certified precision tubes to be integrated into their systems. The processes and products of ETHEN ROHRE are inspected continuously by independent agencies. In particular, ETHEN manufacturing and tubes are approved for use in nuclear power plants.The certificate of the Nuclear Safety Standards Commission (KTA) necessary for that is one of the most exacting quality requirements.
ETHEN ROHRE for research and science
Research and science are most important for smallest dimensions. Only a grain of dust in the wrong place can ruin the result of measurement series in which researchers invested months of work. Therefore, analysers for research and science have to fulfil the most exacting precision standards – and that also applies to the components that are built into them.
Precise manufacturing down to the smallest dimensions is the strong point of ETHEN ROHRE. Therefore, a whole range of leading analyser and measuring device manufacturers producing worldwide for research institutes rely on capillary and precision tubes from ETHEN.
