MST Edelstahlrohr GmbH carries an extensive stock of seamless precision tubes for the use in instrumentation (e.g. flow controls, measuring and analyze application) with smooth bright annealed surfaces and strict requirements to deviation in diameter as well as wall thickness. This reduces the risk of leakages when connecting tubes with single or twin ferrule couplings. Our tubes are suitable for use with couplings from all well known fitting producers in the world.
Instrumentation tubes are stainless, duplex, nickel or titanium tubes, mostly with relatively thin walls. The majority of diameters for instrumentation tubing vary between 1.5 mm OD and 60 mm OD in random lengths of abt. 6 meters or on coils up to 1000 meter long without welds.
The standard tolerance specifications for stainless steel are according to ASTM A 269/A 213/A 632 & EN 10216-5 TC1, ISO 1127 D4/T3 and for duplex, nickel & titanium alloys according to ASTM A 789/B 163/B 165/B 407/B 423/B 444/B 622/B 677 & B338. Our Instrumentation tubes are high quality tubes with EU, US or Japan origin and all kinds of specifications such as: ASTM , ASME, DIN, ISO, EN, NACE, PED, Norsok, AD 2000 W2, TÜV and Lloyd’s Register.
