Ultron Surfaces

Inner surfaces

Ultron is a seamless/welded (depending on outer diameter) stainless steel tube system supplied in the alloys TP316L/TP316/1.4404/1.4435. Ultron is electropolished, quality controlled and packed in our cleanroom and is available with surfaces Ra ≤ 0,13 µm/5 µin, Ra ≤ 0,18 µm/7 µin and Ra ≤ 0,25 µm/10 µin.

Ultron Abbildung Innenoberfläche elektropoliert

Elektropolished:

In accordance to specification HE 175 8VN Rohre/HE 111 8 VN

Characteristics/Advantages:
Minimization of the real surface, closed chromiumoxide layer increases the corrosion resistance, optimized orbital welding behaviour, no catalytic influences on the transported medium.

Outer surface

Ra ≤ 0,80µm
