TCC/TCC.1 Surfaces

Inner surfaces

TCC/ TCC.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 TCC/TCC.1 Innenoberflächen

Bright finish

Cleaned in accordance with ASTM A632, S3,

Ra ≤ 1.00 µm/40 µin, and not defined

Anodic clean

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

Ra ≤ 0.80 µm/32 µin

Ra ≤ 1.00 µm/40 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

Ra ≤ 1.00µm/40 µin
