Tolerances
Characteristic Circular wear tube
Tolerances based on the requirements of EN 10219
Outside diameter (D) ±1%, with a minimum of ±0.5 mm and a maximum of ±10 mm
Out-of-roundness 2%, when D/T ≤ 100
Thickness (T) ±10% when T ≤ 5 mm and ±0.5 mm when T > 5 mm
Straightness 0.20% of total length and 3 mm over any 1 m length
Mass per unit length Individual tube: ±6%
Standard length ≥ 6000 mm: 0/+50 mm
Exact length Agreed at the time of enquiry and order

All external dimensions are measured with a minimum distance from the end of the section. The distance must be a minimum of 100 mm.
