Description
LSAW steel pipe mill China yuantaiderun EN10210-2006
Diameter and roundness deviation (for LSAW straight seam submerged arc welded steel pipes):
Outer diameter tolerance ≤ ± 1%, minimum ± 0.5mm, maximum ± 10mm
The outer diameter measurement method is the circumference method, where the outer diameter is measured as circumference/pi
Ovality: 2% when outer diameter/thickness ≤ 100
Tolerance calculation method=(maximum outer diameter - minimum outer diameter)/standard outer diameter X100%
Wall thickness deviation (for LSAW straight seam submerged arc welded steel pipes):
Outer diameter ≥ 406mm, wall thickness tolerance ≤ ± 10%, maximum ± 2mm
Straightness deviation (for LSAW straight seam submerged arc welded steel pipes, L is the length unit of the steel pipe in mm):
Full length straightness deviation ≤ 0.002L
Quality deviation: ± 6% (per unit length)
Height tolerance of inner and outer weld seams of submerged arc pipes
Thickness (T) ≤ 14.2, maximum weld height 3.5mm
Thickness (T) ＞ 14.2, maximum weld height 4.8mm
Length tolerance:
Any length: 4000-16000mm, with a single floating range of 2000mm. The supplied products can have a 10% lower than the minimum value specified in the order, but cannot be lower than 75% of the minimum value
Approximate length: tolerance range from 0 to+50mm for ≥ 4000mm
Length:
The tolerance range is 0 to 5mm when the length is less than 6000mm
Tolerance range 0 to 15mm when 6000mm ≤ length ≤ 10000mm
When the length is>10000mm, the tolerance is 0 to 5mm+1mm/meter

FAQ
does black steel pipe rust？
Yes,normally, black carbon steel pipes will rust. However, customers do not need to worry too much, as we usually apply oil to the surface of the steel pipe.
