Zimno - walcowane- produkowane w długościach 5-12
m.
Tolerancja na długości dla rur zimno –
walcowanych:
Ø < 50.8 mm - +3/-0 mm; Ø
≥ 50.8 mm - +5/-0 mm;
(W przypadku rur o długości większej
niż 7.3 m, tolerancja wzrasta o +3 mm/3m).

Twardość: 192 HB, 200 HV (90 HRB)
Wymagania zgodne z ASTM A 450
Uwagi:
1. Tubes shall pass tensile
test, flattening test and non-destructive test, they shall be tested for
hardness, and grain size.
2. On special request tubes
shall be submitted to intergranular corrosion test.
3. Tubes of other dimensions
and lengths can be manufactured upon agreement of the customer and the
manufacturer.
Application:
The tubes are used in
presence of high temperature, for example in superheaters
and reheaters.
