TUBE MANUFACTURER ETHEN

Precision and capillary tubes “Made in Germany”

You are here: Home1 /​ Precision and capillary tubes

ETHEN ROHRE is your part­ner for the pro­duc­tion of capillary tubes with out­er diameters from 0.7 mm to 19.05 mm. We have been pro­duc­ing our precision tubes “made in Germany” in Aachen on machines that were devel­oped in-house and can be retro­fit­ted quick­ly. Take advan­tage of these ben­e­fits and have your precision tubes made faster and more flex­i­bly in any quan­ti­ty from a wide range of materials – like innu­mer­able cus­tomers since 1959.

Guar­an­teed reliability

Instru­men­ta­tion tubes are mis­sion-crit­i­cal com­po­nents of many appli­ca­tions and sys­tems. With capillary and precision tubes from ETHEN ROHRE, you are guar­an­teed that your instru­men­ta­tion tubes will func­tion reliably; also in nuclear pow­er sys­tems, for which our tubes are cer­ti­fied →.

Our capillary and precision tubes are avail­able in an extra­or­di­nary range of out­side and inside diameters.
We man­u­fac­ture your tubes with out­side diameters of 0.7 mm to 19.05 mm and wall thick­ness­es of 0.1 mm to 2.5 mm.

Our tol­er­ance stan­dard is +/- 0.05 mm for out­side diameters and +/- 10% for wall thick­ness­es, as well as tolerances accord­ing to DIN EN ISO 1127 D4/​T4.

Dif­fer­ent dimen­sions and tolerances on request.

With­stand­ing per­ma­nent stress

Hydraulic tubes are exposed to extreme­ly high stress dur­ing oper­a­tion. When they fail, this may have seri­ous con­se­quences not only for the sys­tem itself, but also for the environment where they are oper­at­ed. The capillary and precision tubes for these areas of appli­ca­tion have to be select­ed, designed and produced all the more care­ful­ly. ETHEN ROHRE makes your hydraulic tubes to mea­sure from a large range of materials.

Our capillary and precision tubes are avail­able in an extra­or­di­nary range of inside and out­side diameters.
We man­u­fac­ture your tubes with out­side diameters of 0.7 mm to 19.05 mm and wall thick­ness­es of 0.1 mm to 2.5 mm.

Our tol­er­ance stan­dard is +/- 0.05 mm for out­side diameters and +/- 10% for wall thick­ness­es, as well as tolerances accord­ing to DIN EN ISO 1127 D4/​T4.

With­stand­ing max­i­mum stress

When a medi­um flows through a capillary or precision tube under high pres­sure extreme­ly high stress is produced. Wall thick­ness­es and materials have to be tared pre­cise­ly in very small dimen­sions, in order to achieve an opti­mum result. With ETHEN ROHRE as your manufacturing part­ner, you get high-pres­sure tubes that are as del­i­cate as pos­si­ble and as robust as necessary.

The med­ical vari­ant of capillary and precision tubes

ETHEN ROHRE owes part of its growth his­to­ry to med­ical tech­nol­o­gy. This clus­ter also requires a sig­nif­i­cant por­tion of tube pro­duc­tion. In that con­text, capillary and precision tubes are often referred to as “cannula tubes”.

Our capillary and precision tubes are avail­able in an extra­or­di­nary range of inside and out­side diameters.
We man­u­fac­ture your tubes with out­side diameters of 0.7 mm to 19.05 mm and wall thick­ness­es of 0.1 mm to 2.5 mm.

Our tol­er­ance stan­dard is +/- 0.05 mm for out­side diameters and +/- 10% for wall thick­ness­es as well as tolerances accord­ing to DIN EN ISO 1127 D4/​T4.

Heat-resis­tant capillary and precision tubes

Pyrom­e­ter tubes are often used in measurement and con­trol technology.

Our capillary and precision tubes are avail­able in an extra­or­di­nary range of inside and out­side diameters.
We man­u­fac­ture your tubes with out­side diameters of 0.7 mm to 19.05 mm and wall thick­ness­es of 0.1 mm to 2.5 mm.

Resis­tant to car­buris­ing and nitrid­ing atmospheres

ETHEN ROHRE makes ther­mo­cou­ple pro­tec­tive tubes from alloy 600, a nick­el-chrome-iron alloy char­ac­terised by good mechan­i­cal prop­er­ties in all tem­per­a­ture zones. Capillary and precision tubes made of Alloy 600 are man­u­fac­tured by ETHEN ROHRE to the tight­est tolerances and, in addi­tion to their tem­per­a­ture resis­tance, are also char­ac­terised by their sta­bil­i­ty against chlo­rine, hydro­gen chlo­ride, oxi­da­tion, car­buri­sa­tion and stick­ing. Alloy 600 pipes from ETHEN ROHRE are also char­ac­terised by their mechan­i­cal resis­tance to stress cracks.

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.

MATERIALS FOR ALL CAPILLARY AND PRECISION TUBES

ETHEN ROHRE pro­duces sleeves from all materials rang­ing from tita­ni­um to Hastel­loy, nick­el and stainless steel. In order to meet the lat­est standards of your indus­try, we also pro­vide high-performance alloys.

In order to meet the lat­est standards in your indus­try, we offer you high-performance materials made of nick­el alloys in addi­tion to materials such as tita­ni­um or stainless steel. The mate­r­i­al prop­er­ties of these high-performance alloys have been improved by fur­ther addi­tives or by special pro­cess­ing, so that these tubes have improved cor­ro­sion resis­tance, heat resis­tance, weld­abil­i­ty and machinability for a wide range of appli­ca­tions.
