Item specifics


Oversize or call dimension beyond the standard tolerances. Here's "size" mainly refers to the outside diameter and wall thickness of steel pipe. The size tolerance is usually someone used to call "tolerance outrageous" that the bias and tolerance equate imprecise, it is called, should be called "deviation outrageous." Deviations here may be "positive", it may be "negative" and rarely "positive and negative" deviation outrageous phenomenon in the same batch of steel pipe.

Note: The calculation formula used to calculate the theoretical weight profiles:

m = F * L *

m- quality Kg; F- off area m2 / m; L- length m; - density * Kg / m3

Where: F-off area calculation methods:

1, square steel F = a2

2, pipe F = 3.1416 * $ (D- $) D- Diameter $ - Thickness

3, steel, flat steel F = a * $ a- width
