Precision and capillary tubes “Made in Germany”

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.

TYPES OF TUBES

Instrumention tubes Hydraulic — capillary High-pressure tubes Canula Pyrometer tubes Protective tubes

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.

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.

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.

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.

ETHEN ROHRE lying

ETHEN ROHRE horizontal capillary tubes

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.
