A review of 2025

2025 has been a year shaped by precision, respon­si­bil­i­ty and strong partnerships.

From expand­ing our activ­i­ties in the defence sec­tor to strength­en­ing our lead­er­ship team and devel­op­ing our inter­nal process­es, this year has shown how much can be achieved when expe­ri­ence and com­mit­ment come togeth­er. Our capillary and precision tubes have once again proven their val­ue in med­ical engi­neer­ing, ener­gy tech­nol­o­gy, mechan­i­cal engi­neer­ing and increas­ing­ly in defence appli­ca­tions – espe­cial­ly in sen­sor sys­tems, where reli­a­bil­i­ty and resilience are crucial.

At the same time, we have invest­ed in our teams and structures

With the launch of the Coach2Change pro­gramme for our pro­duc­tion lead­er­ship, with a suc­cess­ful­ly com­plet­ed resource-effi­cien­cy project sup­port­ed by EFRE and with important impuls­es from exchanges on dig­i­tal transformation.

Mile­stones that matter

The appoint­ment of Kirsten Von­der­ha­gen as autho­rized sig­na­to­ry, 40 years of ded­i­ca­tion from a val­ued col­league in pro­duc­tion, and the steady growth of our com­mu­ni­ty – includ­ing reach­ing more than 1,000 fol­low­ers on LinkedIn!

Behind every tube stands a team.

A team of ded­i­cat­ed employ­ees who think ahead, take respon­si­bil­i­ty and turn met­al into mil­lime­tre-per­fect precision. Their work shapes ETHEN ROHRE every sin­gle day.And of course: None of this would be pos­si­ble with­out you – our cus­tomers and part­ners.Your trust gives us the con­fi­dence to work with precision, trans­paren­cy and reli­a­bil­i­ty, year after year.

We wish you a peace­ful hol­i­day sea­son and a strong start to the new year.

Please note: We will be on hol­i­day from Decem­ber 23, 2025 to Jan­u­ary 04,2026.In the new year we return recharged and ready to sup­port you with the same com­mit­ment and precision you rely on.

High-performance alloys in capillary and precision tubes

Our mate­r­i­al for the most demand­ing requirements

At ETHEN ROHRE, we have been manufacturing capillary and precision tubes from high-performance alloys for many years. These high-performance alloys are made for extreme con­di­tions. Wher­ev­er stan­dard materials reach their lim­its, they ensure safe­ty, sta­bil­i­ty and func­tion­al­i­ty. No two appli­ca­tions are alike. That is why we do not sup­ply stan­dard solu­tions, but pre­cise­ly man­u­fac­tured tubes that can be adapt­ed exact­ly to the respec­tive application.

High-performance alloys are used wher­ev­er materials are under con­stant pres­sure. In med­ical engi­neer­ing, chem­i­cal indus­try, ener­gy pro­duc­tion or avi­a­tion, dimensional accu­ra­cy, cor­ro­sion resis­tance and heat sta­bil­i­ty are cru­cial every­where. That is exact­ly what our materials are made for. And that is exact­ly why we at ETHEN devel­op solu­tions you can rely on.

Why ETHEN relies on high-performance alloys

Many of our cus­tomers’ appli­ca­tions place extreme demands on mate­r­i­al prop­er­ties. Chem­i­cal process­es require per­ma­nent cor­ro­sion resis­tance, in ener­gy tech­nol­o­gy tubes must remain dimen­sion­al­ly sta­ble under high tem­per­a­tures and high pres­sure, and in med­ical engi­neer­ing micro­scop­ic precision and absolute mate­r­i­al puri­ty are essential.

Materials such as nick­el alloys, tita­ni­um and stainless steels offer pre­cise­ly these prop­er­ties. They are mechan­i­cal­ly resilient, heat-sta­ble and reli­able in their func­tion – even under long and inten­sive stress. At the same time, they enable the pro­duc­tion of extreme­ly thin-walled tubes with tight tolerances. This is a key fac­tor in the man­u­fac­ture of capillary tubes and one of our core competencies.

Precision pro­cess­ing tai­lored to the material

These materials require the high­est precision in pro­cess­ing. And that is pre­cise­ly our strength. ETHEN process­es a wide range of high-performance alloys, includ­ing nick­el and tita­ni­um alloys as well as special materials for spe­cif­ic applications.

The man­u­fac­ture of precision tubes from high-performance alloys requires special form­ing process­es, con­trolled heat treat­ments and state-of-the-art draw­ing and smooth­ing tech­nolo­gies. Many of these materials are sensitive to devi­a­tions in the process, whether in tem­per­a­ture con­trol, lubri­ca­tion or fin­ish­ing. At ETHEN, we have decades of expe­ri­ence in the mate­r­i­al-spe­cif­ic pro­cess­ing and man­u­fac­ture of tubes, which means they always meet the high­est quality and documentation require­ments.

Tai­lor-made solu­tions for demand­ing applications

ETHEN TUBES stands for tech­ni­cal precision, reli­able process­es and part­ner­ship-based coop­er­a­tion. Our cus­tomers know that high-performance appli­ca­tions require not only the right mate­r­i­al, but also a part­ner who knows how to work with it.

We do not sup­ply off-the-shelf tubes, but rather cus­tomised solu­tions, with special dimen­sions or spe­cial­ly tai­lored alloys on request. We always keep the big pic­ture in mind: func­tion­al­i­ty, cost-effec­tive­ness and durability.

High-performance alloys are the key to safe, resilient prod­ucts in com­plex tech­ni­cal envi­ron­ments. With our capillary and precision tubes made of high-performance alloys, we are mak­ing an important con­tri­bu­tion to the future of mod­ern technologies.

Talk to us about your appli­ca­tion. Togeth­er we will find the right material.

Increased exper­tise in the defence sector

Stand­ing still is not an option for us. As a tube manufacturer with over 100 years of expe­ri­ence, it is our aim to con­stant­ly devel­op our­selves fur­ther, tech­ni­cal­ly, organ­i­sa­tion­al­ly and also in the areas of appli­ca­tion that we serve. After all, precision and reli­a­bil­i­ty are char­ac­ter­is­tics that are in demand in many indus­tries and that we pro­vide with our capillary and precision tubes. We are cur­rent­ly focus­ing on build­ing on our exist­ing activ­i­ties in the defence sec­tor → and strength­en­ing them in a tar­get­ed manner.

For years, we have been sup­ply­ing tubes for appli­ca­tions that require max­i­mum precision and resilience — includ­ing for sen­sor com­po­nents in the defence sec­tor. We want to use this expe­ri­ence to make our exper­tise even more vis­i­ble in demand­ing applications.

Our capillary and precision tubes are used where the high­est require­ments pre­vail: in sen­sor sys­tems, test and inspec­tion sys­tems or oth­er com­plex appli­ca­tions. They can with­stand extreme con­di­tions: from strong vibra­tions to high pres­sure and tem­per­a­ture fluctuations.

In this way, we make a reli­able con­tri­bu­tion to resilience and sta­ble indus­tri­al val­ue cre­ation on site.

At home in many indus­tries. In yours too.

Our capillary and precision tubes come into play as soon as fil­i­gree struc­tur­al com­po­nents and the high­est quality are required. The mil­lime­tre-pre­cise tubes and sleeves have to be able to with­stand a lot, and this requires sen­si­tiv­i­ty and expertise.

Our prod­ucts are used wher­ev­er absolute reli­a­bil­i­ty is required: in large series, safe­ty-crit­i­cal appli­ca­tions and sys­tem-relevant instal­la­tions. Our cer­ti­fi­ca­tions pro­vide the for­mal basis, but the deci­sive fac­tor is our aspi­ra­tion to always go that lit­tle bit further.

This is where we are at home:

Appa­ra­tus engi­neer­ing: In com­plex sys­tems, every component must func­tion — with­out com­pro­mise. Our tubes ensure a pre­cise fit and thus con­tribute to smooth performance. Read more

Auto­mo­tive indus­try: Whether high-pres­sure sys­tems or con­trol lines, tubes in vehi­cles are exposed to extreme tem­per­a­tures, vibra­tions and high loads. We sup­ply dimen­sion­al­ly accu­rate, robust solu­tions that meet the industry’s strict safe­ty standards. Read more

Chem­i­cal indus­try: Dura­bil­i­ty is cru­cial here. Our stainless steel, nick­el or tita­ni­um tubes with­stand aggres­sive media and offer max­i­mum process reli­a­bil­i­ty, even in the most demand­ing appli­ca­tions. Read more

Your tubes: man­u­fac­tured in Aachen, test­ed for quality.

For us at ETHEN ROHRE, ‘Made in Germany’ is far more than just a label. It stands for a promise of quality that you can rely on at all times and for the val­ues that have char­ac­terised our work for over 100 years: Safe­ty, trust and reliability.

All steps from a sin­gle source in Aachen

Our capillary and precision tubes are man­u­fac­tured entire­ly in Germany. From pro­duc­tion and fin­ish­ing to the final quality inspec­tion, every­thing takes place at our plant in Aachen. This high degree of in-house pro­duc­tion ensures that we have com­plete con­trol over our process­es and that you receive prod­ucts that meet the exact spec­i­fi­ca­tions you require.

Safe­ty through test­ed quality

Our tubes are man­u­fac­tured under strict quality standards. TÜV cer­ti­fi­ca­tions, state-of-the-art test­ing pro­ce­dures and close mon­i­tor­ing of each indi­vid­ual pro­duc­tion step give you the cer­tain­ty that our prod­ucts will func­tion reliably even in the most sensitive appli­ca­tions. For us, safe­ty means not only tech­ni­cal precision, but also the knowl­edge that you can rely on us.

Trust through trans­paren­cy and experience

Trust is cru­cial, espe­cial­ly in a chal­leng­ing mar­ket environment. That’s why we rely on open com­mu­ni­ca­tion: if there are any bot­tle­necks or delays, we will let you know in good time so that you can plan reliably. Our many years of expe­ri­ence in pipe pro­duc­tion form the basis for this secu­ri­ty — com­bined with the con­tin­u­ous devel­op­ment of our process­es and technologies.

Not all tubes are the same. What char­ac­teris­es our capillary and precision tubes.

From the mate­r­i­al and pro­cess­ing to the cut length, every­thing has to be just right for us. Because every sin­gle detail counts in the end. We not only offer stan­dard solu­tions, but also the right answer to com­plex requirements.

Our prod­uct range includes a vari­ety of tube types that are used in dif­fer­ent areas of appli­ca­tion. From appa­ra­tus and equip­ment engi­neer­ing to med­ical tech­nol­o­gy and the sci­en­tif­ic sector.

For exam­ple, we manufacture

  • instru­men­ta­tion tubes for high-precision measurement and con­trol processes,
  • hydraulic and high-pres­sure tubes for robust, pres­sure-resis­tant sys­tems or
  • par­tic­u­lar­ly fine cannula tubes for the med­ical sector,
  • pyrom­e­ter tubes for tem­per­a­ture measurement appli­ca­tions or
  • pro­tec­tive tubes for sensitive components

are all part of our programme.

Precision down to the small­est detail, because size matters.

What sets us apart is not only the vari­ety of tube types, but also the precision of our workmanship:
We man­u­fac­ture with exter­nal diameters from 0.7 mm to 19.05 mm, with wall thick­ness­es between 0.10 mm and 2.50 mm — even out­side this range on request. Our ETHEN tol­er­ance stan­dard is OD ± 0.05 mm and WD ± 10 %, although we can also realise tighter tolerances on request.

We also offer par­tic­u­lar flex­i­bil­i­ty in terms of length: whether it’s min­i­mal­ly short sleeves from 2 mm or pre­cise­ly cut tubes up to 6,400 mm, our pro­duc­tion cen­tre allows cus­tomised work with precision — even to dec­i­mal places.

Our materials

And because every project requires its own mate­r­i­al, our mate­r­i­al port­fo­lio includes, among others:
Tita­ni­um (light, strong, bio­com­pat­i­ble), nick­el and nick­el alloys (tem­per­a­ture and cor­ro­sion resis­tant), stainless steel (proven, sta­ble) as well as special materials and high-performance alloys for the high­est requirements.

Our tubes are produced exact­ly accord­ing to your spec­i­fi­ca­tions and ideas — sim­ply let us advise you.

Because one thing is cer­tain for us: the best solu­tion is always the one that fits.

Reli­able con­sul­ta­tion that thinks along with you. Because trust is no coincidence.

In a dynam­ic environment with com­plex require­ments, you need a part­ner you can rely on. For us at ETHEN ROHRE, this not only means quality in pro­duc­tion, but also in communication.

Because one thing is clear to us:

Resilient process­es start with a reli­able dialogue.

Our advice is more than just a rec­om­men­da­tion as to which capillary or precision tube or mate­r­i­al is best for your appli­ca­tion. With over 100 years of expe­ri­ence in the man­u­fac­ture of capillary and precision tubes, we can help you find the right com­bi­na­tion of tube, mate­r­i­al, dimen­sion and ver­ti­cal range of man­u­fac­ture for your application.

Important to us:

Com­mit­ment: A per­son­al con­tact per­son accom­pa­nies you through­out the order process
Trans­paren­cy: Do you have a few changes or queries? We talk to you clear­ly and in good time?
Flex­i­bil­i­ty: If some­thing needs to be adjust­ed at a lat­er date, we will work with you to find a solu­tion. Prag­mat­ic and solution-orientated.

Trust is only created where you can rely on the process­es, peo­ple and state­ments. For us, this is a cen­tral part of resilience.

Let us advise you!

We will dis­cuss with you what your project needs from us: From the pro­duc­tion of capillary and precision tubes in 0.7 to 19.05 mm out­er diam­e­ter or our ETHEN Tub­ing Plus service.

Materials with an effect for pre­cise applications

Not every mate­r­i­al is the same, and not every area of appli­ca­tion has the same require­ments. We at ETHEN ROHRE are aware of this and there­fore rely on a tar­get­ed selec­tion of high-quality materials. Nat­u­ral­ly, always tai­lored to your area of appli­ca­tion and with you as the customer.

Our materials at a glance:

Tita­ni­um — strong, light and corrosion-resistant

Tita­ni­um is an incred­i­bly light yet extreme­ly strong mate­r­i­al; per­fect for devices that have to with­stand high loads. Tita­ni­um also has an excep­tion­al­ly low sus­cep­ti­bil­i­ty to aller­gies, which makes it the ide­al choice for direct use on patients with sensitive reac­tions or met­al intol­er­ances. Tita­ni­um is there­fore often indis­pens­able in med­ical tech­nol­o­gy in particular.

Nick­el and nick­el alloys — resis­tant under extreme conditions

Nick­el and nick­el alloys are used when things get par­tic­u­lar­ly chal­leng­ing: for exam­ple, in high tem­per­a­tures, aggres­sive media or cor­ro­sive envi­ron­ments — such as in the chem­i­cal indus­try, measurement tech­nol­o­gy or pow­er generation.

Stainless steel — proven, ver­sa­tile, pre­cise processing

Stainless steel impress­es with max­i­mum cor­ro­sion resis­tance, out­stand­ing sta­bil­i­ty and excel­lent process­abil­i­ty. It is used in med­ical tech­nol­o­gy due to its hypoal­ler­genic prop­er­ties. The mate­r­i­al is kind to the skin and reduces the risk of unwant­ed reac­tions — espe­cial­ly in direct patient con­tact or in the area of implants.

Special and high-performance materials — for that cer­tain ‘extra’

Special and high-performance materials offer max­i­mum resis­tance with min­i­mum tol­er­ance — ide­al for appli­ca­tions where stan­dard solu­tions reach their lim­its. Here we rely on high-performance nick­el-based alloys that are char­ac­terised by tem­per­a­ture sta­bil­i­ty, cor­ro­sion resis­tance and durability.

Why do we take this so seriously?

Because the right mate­r­i­al makes all the dif­fer­ence. For the performance, service life and safe­ty of your appli­ca­tions. That’s why we are hap­py to advise you indi­vid­u­al­ly on your selec­tion and cus­tomise the mate­r­i­al, dimen­sions and pro­cess­ing pre­cise­ly to your requirements.
