finetron/finetron.1 Surfaces

Inner surfaces

finetron/finetron.1 – a seamless/welded (depending on outer diameter) stainless steel tube system supplied in the alloys TP316L/TP316/1.4404/1.4435 and available in the surface qualities bright finish and anodic clean.

Abbildung Finetron/Finetron.1 Innenoberflächen

Bright finish

Cleaned in accordance with ASTM A632, S3,

OD ≤ 63.50 mm Ra ≤ 0.40 µm/16 µin

OD > 63,50 mm Ra ≤ 0.60 µm/24 µin

Anodic clean

Anodic cleaned in accordance with specification HE 175 3VNS (tubes) and HE 111 3VNS (fittings)

OD ≤ 63.50 mm Ra ≤ 0.40 µm/16 µin

OD > 63,50 mm Ra ≤ 0.60 µm/24 µin

Anodic cleaning does not alter the roughness of the inner surface

Characteristics/Advantages:
The specially developed cleaning process removes 3-5µm from the surface – and with it any remnants of the annealing process and other potential contamination. For the user this means a surface free of particles including the welds.

Outer surface

Outer surface: Ra ≤ 0.80 µm/32 µin
