Negative deviation in SW6 steel pipe thickness

2020-04-09View Original

Thread Content

Today, when using SW6 to calculate the reinforcement for openings, it was found that the negative deviation in the thickness of S30408 fittings is as follows: for S≤12, the negative deviation is 10%S; for 12＜S≤14, the negative deviation is 1.4%; and for S≥14, the negative deviation is 10%S. S is the wall thickness. I feel very confused; is it the same for you guys?

What does that mean? Is a thickness between 12 and 14 considered as 14? I really hadn’t noticed this…

The thicknesses are different, as are the negative deviations; refer to the specifications in HG/T20581
